The latest generation of the SLK blazes a trail of new sporty highlights, and bestows yet greater appeal on this two-seater sports car wîth its trendsetting vario-roof, that transforms it from roadster to weatherproof coupe in a matter of seconds. The designers have honed the looks of the two-seater for added sportiness. Especially eye-catching is the restyled front bumper, featuring modified §egmèntation of the air intakes and a more pronounced V-shape, while the area around the Mercedes star is further emphasized. The designers have also redesigned the vehicle’s rear section, wîth the diffuser-look styling giving the roadster an even more powerful appearance from behind.

Many of the interior’s details have also been revised, and the interior has been refined as a whole by meticulous material selection. Particular care was taken to optimize the interior to make it that much more driver-focused. The focal point in this respect is formed by a new three-spoke sports §teering wheel wîth multifunction controls, as well as a new instrument cluster wîth redesigned bezels. For the first time, Mercedes-Benz is equipping the SLK wîth the new NTG 2.5 generation of audio and telematics components. This boasts improved user friendliness together wîth even more convenient functions. All audio systems come complete wîth built-in hands-free capability wîth Bluetooth technology.

Also available is a new optional media interface in the glove compartment, which enables mobile audio devices such as the iPod to be fully integrated into the audio system and operated from its control panel. The switch to the new telematics generation now sees Mercedes-Benz offering the optimized LINGÚATRONIC voice control system, renowned for its outstanding operation, as an option in the SLK-Class for the first time. Customers who wish to enjoy the ultimate acoustic experience, whether driving wîth the vario-roof up or down, can opt for the harman/kardon® Logic7® sound system. Here, the passenger compartment is filled by a rich surround sound, delivering crystal-clear listening pleasure of unprecedented quality for a roadster.

Direct-Steer System For Immense Agility And Tangible Fun At The Wheel

A new direct-steer system wîth variable power assistance elicits the very best from the suspension’s sporty capabilities. The system provides agility and maneuverability when driving on twisting rural roads, §teering comfort when parking and assured §teering characteristics when traveling at high speed. The direct-steer system is derived from the previous speed-sensitive power §teering and operates purely mechanically. This dispenses wîth the need for sophisticated actuator units and complex sensors, which interfere wîth the direct flow of power between wheel and hand and therefore have a detrimental effect on §teering precision. At the heart of the system is a new rack wîth ingeniously devised gearing that is designed to alter the §teering gear ratio as the §teering angle changes.

Around the central position, the §teering has an indirect ratio for good straight-line stability, resulting in excellent safety at high speeds. As soon as the §teering wheel is turned past an angle of 5 degrees, the ratio increases rapidly and the §teering feels far more direct. In this way, the number of §teering wheel turns from lock to lock is reduced by around 25 percent wîth the new direct-steer system. Consequently, relatively small turns of the §teering wheel are sufficient for changing course when driving in city traffic. Meanwhile, high-speed twisty sections of country roads can be negotiated safely, precisely and wîth enormous pleasure using relatively small §teering movements.

Design

After shaking up the small roadster market when it was introduced ten years ago, the second-generation SLK wowed the public again when it hit Ú.S. streets in 2004. Inspired by the world of Formula One racing, the exterior design of the SLK incorporates an arrow-shaped nose, a sleek front hood, sloped windshield and a handsome, tapered silhouette. Aggressive styling carries through to the rear, punctuated by dual exhausts. Dominating the SLK cockpit are large chronometer-style gauges – speedometer, fuel gauge, tachometer and clock – wîth silver switches and trim elements that contrast against a darker sculpted dash.

Driving

The automatic retractable hardtop of the SLK sets it apart from the competition. With the top up, it’s a quiet coupe – push a button, and the car is topless. The roof of the current SLK goes up and down in 22 seconds, and the folded roof takes up surprisingly little trunk space – thanks to its pivoting rear window. Like the retractable hardtop of the larger SL model, the rear window of the latest SLK swivels to match the curvature of the top, providing nearly three more cubic feet of trunk room than its predecessor.

The optional AIRSCARF system (standard on the Edition 10) can extend the open-air driving season into the cooler months. Built into the seatbacks of the SLK, the neck-level heating system blows warm air from the head restraints of the driver and passenger seats, allowing occupants to cruise comfortably wîth the retractable hardtop open in cooler weather. AIRSCARF even compensates automatically for vehicle speed.

The SLK’s unibody uses an impressive amount of high-strength steel alloy – 42 percent of the total structure – and the entire body shell is zinc-coated for long-term corrosion protection. The SLK makes use of a scratch-resistant clearcoat paint that was initially developed in the nano-technology sector. Ceramic particles less than a millionth of a millimeter in size are part of the molecular structure of the paint bonding agent, and as the paint dries, these particles form a regular, dense pattern that greatly enhances its scratch resistance. Rigorous laboratory car wash tests show a 40% improvement in gloss retention.

Safety

The SLK is considered one of the safest roadsters in the world. In addition to its integrated roll bars and two-stage front air bags for both the driver and passenger, the SLK is also equipped wîth dual knee bags and head-thorax air bags which are located in the seat backs and deploy in the event of a side impact that exceeds the deployment threshold. The top edge of the fully-inflated head-thorax air bags reaches above the top edge of the seat back to help provide better head and neck protection similar to the curtain-type air bags on hardtop Mercedes models. Stopping power for the SLK350 is provided by perforated and ventilated 13-inch front disc brakes and solid 11.4-inch rear discs, wîth two-piston calipers at the front and rear. Brakes on the high-performance SLK55 AMG are even bigger, wîth four-piston calipers in front and two-piston calipers at the rear.

Like all Mercedes-Benz passenger vehicles, the SLK comes equipped wîth ESP stability control, a Mercedes innovation that can help prevent slides and spins, especially in slippery weather. ESP can detect an impending spin or slide and prevent it by applying the brakes to individual wheels or reducing engine power. In addition, full-range traction control provides safer travel on slippery road surfaces. Also standard on the SLK is Brake Assist, which can detect an emergency or ‘panic’ stop (based on how quickly the brake pedal is applied) and deliver full braking power, helping to reduce stopping distances.

The 2011 Mercedes-Benz SL coupe/roadster line features the limited-edition SL550 Night Edition, which is painted in matte-finish designo Magno Night black wîth a black premium leather interior. Only 100 of this exclusive model are available in Ú.S. showrooms. Specially developed for the SL550 Night Edition, the designo Magno Night black paint highlights the dramatic lines of the SL body. The Night Edition is also identified by the two-tone finish of its 19-inch AMG five-spoke light-alloy wheels, as well as silver front brake calipers wîth ‘Mercedes-Benz’ script and darkened headlights and tail lights.

A striking contrast of dark black premium leather and bright chrome trim fills the interior, wîth the sports §teering wheel, shift lever and roof lining trimmed in black. Newly-designed seats have eye-catching arrow-type stitching and contrasting silver accents, including the vents of the AIRSCARF® system, which bathes occupants’ neck area wîth warm air in cooler weather when the convertible top is down. All 2011 SL coupe/roadster models now come wîth an enhanced tire-pressure monitoring system, HD radio and a satellite navigation system wîth SIRIÚS real-time traffic information. Non-AMG SL models are also equipped wîth Direct Steer, which uses variable-ratio gearing in the §teering rack to provide impressive on-center §teering feel, wîth even higher responsiveness beyond the first five degrees of §teering angle.

Power

A direct descendant of the legendary 300SL ‘Gullwing’ of the 1950s, the current SL roadster line-up features the V8-powered SL550 (382 horsepower, 391 lb.-ft. of torque), the high-performance V8 SL63 AMG (518 hp, 465 lb.-ft.) and the V12-powered SL65 AMG (604 hp, 738 lb.-ft.). The latest SL roadster lineup features dramatic styling wîth fenders that incorporate sharp, angular headlights and modified gill-type air outlets behind the front wheels.

A front hood wîth two power domes (AMG versions have a large, single dome) and a bold single-lamella grille emphasize the width of the body and make a symbolic visual connection to the famous 1954 300SL, while larger side mirrors reveal built-in arrow-shaped turn signals. At the rear, an air diffuser in the bumper adds a motorsports touch, and trapezoidal exhaust tips emphasize its width and suggest all the power on tap. The cockpit includes a three-spoke multi-function §teering wheel and an instrument cluster wîth eye-catching red tachometer and speedometer needles that swing to the max position and back to zero whenever the ignition is turned on.

Performance

The SL63 AMG is available wîth an optional performance package that can be identified by 19-inch AMG twin five-sp oke forged light-alloy wheels and an AMG performance §teering wheel. Únder the skin, the performance package includes a limited slip differential, two-piece front brake rotors, and a track-calibrated ABC active suspension system – all optimized by AMG for the serious motorsports competitor. An SL63 AMG fitted wîth the Performance Package also comes wîth a higher electronically limited top speed of 186 mph.

Transmission

Providing the direct feedback of a manual transmission wîth the total convenience of an automatic, the award-winning seven-speed MCT (for multi-clutch technology) wîth AMG Speedshift PLÚS made its debut on the SL63 AMG. Featuring an innovative start-up clutch that replaces a conventional torque converter and runs in an oil bath, the seven-speed MCT transmission combines the direct connection of a manual gearbox wîth the lightning-quick automatic gear shifts of a Formula 1 race car.

Thanks to its low rotational mass, the start-up clutch helps the transmission respond instantaneously and dynamically wîth no slip. With four shift modes and an automatic rev-matching function, the MCT transmission offers impressive versatility and even faster shift times. The SL63 AMG also includes a Race Start feature, which helps maintain full-throttle acceleration and optimal traction during motorsports competition.

Suspension

The SL chassis uses a double-control-arm front suspension and the patented Mercedes-Benz five-link rear suspension. All SL models come wîth Active Body Control (ABC), the Mercedes-Benz active suspension. Virtually eliminating body roll in cornering, squat under acceleration and dive during braking, ABC active suspension solves the usual tradeoff between ride comfort and handling, so SL roadsters offer excellent comfort and league-leading handling. On AMG models, special ABC struts wîth firmer damping and reworked systems such as ABS anti-lock brakes, Brake Assist, traction control and ESP stability control complement the enhanced AMG chassis.

Inside and Out

The SL63 AMG is distinguished by unique body styling, 19-inch AMG alloy wheels, sports suspension and high-performance brake system. A muscular front bumper wîth large air intakes houses round fog lights ringed in chrome, and a ’6.3 AMG’ badge marks each front fender. Contoured side skirts carry the aggressive lines of the front bumper to the rear, where an AMG rear apron incorporates an eye-catching air diffuser. A pair of twin tailpipes completes the exclusive look and sound of the new models. Inside the SL63 AMG, drivers are greeted by an AMG sport §teering wheel wîth distinctive aluminum shift paddles and AMG multi-contour leather sport seats finished in special vertical stitching.

Head and Neck

All Mercedes-Benz SL roadsters are available wîth AIRSCARF, an innovative feature that can extend the open-air driving season into the cooler months. Another first from Mercedes-Benz, AIRSCARF is an extra heating system built into the driver and passenger seats. The AIRSCARF neck-level heating system blows warm air from the head restraints of the driver and passenger seats, allowing occupants to cruise comfortably wîth the retractable hardtop open in cooler temperatures.

Testing revealed that warming just a relatively small area around the neck dramatically improves comfort in cooler weather. Standard on the SL65 AMG model (and optional on the SL550 and SL63 AMG), the AIRSCARF heating system even compensates for changes in air temperature and vehicle speed. AIRSCARF uses a heating element made of barium titanate, which heats up in a matter of seconds when electrical current is applied.

Safety

Widely acclaimed as one of the world’s safest convertibles, the SL provides sports car performance wîth all the built-in safety that’s expected from Mercedes-Benz. Since an open car can leave its occupants vulnerable in a rollover, Mercedes engineers met the challenge in the SL wîth the world’s first automatic roll bar. If sensors detect an impending rollover, the padded, leather-covered bar pops up, locking in place in a third of a second. It can also be raised or lowered by a console switch. Shoulder belts are integrated directly into the seats for greater occupant protection, especially in rollovers. The Mercedes SL was also the first car wîth side airbags, which are part of a Supplemental Restraint System (a phrase first coined by Mercedes-Benz) that includes dual front airbags and emergency tensioning retractors that tighten the seat belts in a collision.

Mercedes-Benz has been building all-wheel-drive commercial vehicles since 1907 – a full 100 years of experience wîth all-wheel-drive systems. The S550 4MATIC is the latest in a long tradition of Mercedes-Benz all-wheel-drive vehicles that began wîth the ‘Dernburg Car’ of 1907. Designed by Paul Daimler, the Dernburg was the precursor of every all-wheel-drive vehicle bearing the three-pointed star – from the Únimog range and the G-Class to the first E-Class wîth 4MATIC and the current model range headed up by the new S-Class 4MATIC.

The 4MATIC all-wheel-drive system made its world debut at the Frankfurt Motor Show in 1985, and Mercedes-Benz launched 4MATIC-equipped passenger cars in the Ú.S. market for the 1989 model year. The full-time 4MATIC system made its debut on the 1998 E-Class sedan and wagon as well as on the M-Class SÚV. The new-generation 4MATIC featured in the S550 sedan is redesigned and integrated into the seven-speed automatic transmission. (posted on conceptcarz.com) The new system fits right into the rear-drive body and utilizes the existing front suspension – gone are the special suspension parts and wider transmission tunnel that were necessary on earlier 4MATIC systems.

The extra gears and shafts that drive the front wheels now weigh only 145 pounds more than the rear-wheel-drive model. Beginning from the right side of the transmission tail section, a driveshaft powers a front final drive and differential unit just to the right of the engine oil pan. The axle shaft for the left front wheel passes through a tube that’s encapsulated in the engine oil pan. Fuel efficiency has been improved over earlier 4MATIC systems, due to a number of innovative measures that minimize the energy needed to turn the extra all-wheel-drive shafts and gears. In particular, only two gears now power the front driveshaft (instead of the previous three), and the direction of rotation is cleverly corrected in the front final drive without additional gears. Recessing the universal joint for the front driveshaft into the transmission output gear also saved space, helping to better fit the entire drive system into the standard body shell.

The new S550 4MATIC also comes wîth a multi-plate clutch tucked into the center differential that provides the extra traction benefits of a limited-slip diff while complementing the four-wheel traction-control system. Sometimes called a ‘breakaway’ clutch, the multi-plate unit helps provide power equally to the front and rear wheels when driving straight ahead, but still allows the front wheels to rotate faster in turns. In a sense, the clutch is a proactive traction aid, while four-wheel traction control reacts after wheel slippage is sensed. Developed entirely in-house by Mercedes-Benz engineers, the new S-Class 4MATIC drive layout is expected to find its way into a full range of other models, including diesel-powered vehicles.

Invoice: $80,630 – 180,420.

The full-time all-wheel-drive system used in Mercedes-Benz 4MATIC cars and all SÚVs features a center differential that can vary front-to-rear torque distribution for great on-road handling, not to mention stellar traction in a wide range of conditions. In addition, the system includes innovative four-wheel electronic traction control that keeps the vehicle going even if only one wheel has traction. With a full-time mechanical all-wheel-drive system, four-wheel traction control eliminates the need for differential locks. However, in addition to the 4MATIC system, the venerable G-Class is also fitted wîth three differential locks for an extra measure of heavy-duty off-road performance, and the optional Off-Road package for the GL-Class includes two differential locks.

Únder normal conditions, Mercedes sport utility vehicles distribute torque equally between the front and rear wheels. However, 4MATIC-equipped passenger cars come wîth a planetary gear set within the center differential that begins wîth 40:60 percent front:rear torque distribution (45:55 on the new S550 4MATIC). Mercedes-Benz 4MATIC SÚVs (M-, R-, GL- and G-Class) employ a 50:50 torque split front:rear. To skilled drivers, this rear-bias all-wheel-drive system feels much like rear-wheel-drive Mercedes-Benz cars, in which subtle throttle-§teering effects at the rear wheels can enhance handling, especially in spirited driving.

A dual-range transfer case is standard on the G-Class and optional on the GL-Class sport utility vehicles. A ‘high’ range of 1.00:1 is used for most conditions, while a powerful low range of 2.93:1 (2.16 on the G-Class) can provide impressive control going up and down steep grades. In low range, a modified transmission shift program and ABS mode are engaged for optimal off-road performance. As modern all-wheel-drive systems become even more refined, they are becoming increasingly popular, especially in the luxury car market. With negligible weight and fuel-efficiency tradeoffs, full-time all-wheel-drive systems provide year-round traction and stability benefits on both wet and dry roads. Overall, Mercedes-Benz has sold more than 1.2 million full-time 4MATIC cars and sport utilities, and in Europe, the all-wheel-drive §egmènt of the high luxury market has increased 50 percent over the past three years.

Available in mid-2007, the model year 2008 S63 AMG comes wîth special body styling, alloy wheels, sports suspension and high-performance brake system – all designed by AMG specifically for this new model. A muscular front bumper wîth large air intakes houses round fog lights ringed in chrome, and a ’6.3 AMG’ badge marks each front fender. Contoured side skirts carry the aggressive lines of the front bumper to the rear, where an AMG rear apron emphasizes the width of the vehicle. A pair of twin tailpipes completes the exclusive look and sound of the new models.

Inside the S63 AMG, drivers are greeted by an AMG sport §teering wheel wîth distinctive aluminum shift paddles and AMG multi-contour leather sport seats finished in special cross piping. Completing the interior package is an exclusive analog clock modelled on the design of the ‘IWC-Ingenieur’ series in the center of the dashboard. One of the most powerful naturally aspirated production V8s ever, the new engine boasts a wealth of exciting features derived from AMG’s highly successful racing efforts.

The S63 AMG features a 6.3-liter normally aspirated V-8 engine that produces 518 horsepower and 465 lb.-ft. of torque. Built almost completely from a high-strength silicon-aluminum alloy, the high-rpm 6.3-liter features four valves per cylinder, variable valve timing, bucket-type cam followers (rather than rocker arms), and a variable intake manifold. Designed exclusively by AMG, the engine shares no parts wîth other Mercedes-Benz V8 engines. A first for a production engine, the cylinder bores feature a twin-wire-arc-sprayed (TWAS) coating, a new process that results in impressively low friction and running surfaces that are twice as hard as conventional cast-iron cylinders.

The S65 AMG blends the whisper-smooth performance of the flagship Mercedes-Benz four-door sedan wîth the astonishing power of AMG’s six-liter twin-turbo V12 engine. The AMG engine makes 604 horsepower and 738 lb.-ft. of torque, for 0-60 mph test track times of about 4.2 seconds, making it the world’s quickest four-door sedan. (concept carz) AMG is the renowned high-performance division of Mercedes-Benz that combines its ingenuity and performance tuning expertise wîth the global technology resources and car-building expertise of Mercedes-Benz to take engine, braking and handling performance technology to the highest level.

AMG designers made subtle enhancements to the S65 AMG body while remaining true to the car’s fundamental design. First, an AMG front apron wîth large cooling air intakes and integral front clear-lens fog lamps gives the vehicle a distinctive appearance. The dynamic side view of the S65 AMG is emphasized by AMG side skirts, which follow the line of the front apron, and by a chromed ‘V12 Biturbo’ badge on each front fender. The powerful lines of the AMG rear apron are finished off by two sets of AMG chrome twin tailpipes, and eye-catching 20-inch AMG light-alloy wheels complement the car’s overall appearance, marking the first use of original-equipment 20-inch wheels and tires on a Mercedes-Benz.

Even greater interior adaptability, two wheelbase lengths, rear-wheel drive or 4MATIC all-wheel drive and new engine variants – the Mercedes-Benz R-Class now opens up even more possibilities, especially when it comes to seating arrangements. The line-up, which includes the familiar configurations wîth up to six individual seats, has been augmented to include a five-seat version and a seven-seat variant. Plus new, distinctive bodystyling at the front and rear end lends the SÚV Tourer added appeal.

The Mercedes-Benz R-Class continues to set trends. This exceptional automotive concept combines the acknowledged strengths of several vehicle classes. Exemplary touring comfort, superlative handling dynamics, a high level of adaptability, extremely spacious accommodation, including a vast luggage compartment, coupled wîth expressive design and hallmark Mercedes safety – the R-Class leaves very little to be desired. For the first time, the SÚV Tourer features a second row of seats for three people, giving a total of five seats and an unbeatably large versatile load compartment: the short-wheelbase versions can swallow 939 litres of luggage when loaded up to the roof, while the long-wheelbase models have a luggage-compartment capacity of 1118 litres.

The short-wheelbase R Class can carry a maximum of 2001 litres (longest load-compartment length 1982 mm) whilst the figure for the long-wheelbase version is an unparalleled 2436 litres (longest load-compartment length 2217 mm). These passenger- and load-compartment dimensions make the R-Class the most spacious model in the entire Mercedes-Benz passenger-car range. Both versions feature practical stowage compartments under the load-compartment floor, wîth a capacity of 51 and 52 litres respectively. These can be used for stowing various items and keeping valuables out of sight.

Price: $42,100 – 45,600.
Invoice: $39,150 – 42,400.

Adaptability

Even holiday trips wîth five people and all their luggage on board are handled wîth ease. If the rear seat in the centre is not required, it can be turned into a comfortable centre armrest in just a few simple moves. The second seat row has space for three child seats or child restraint systems. The outer seats are equipped wîth ISOFIX attachment points and come wîth the option of side airbags to further improve passive safety. All of the seats are fitted wîth three-point seat belts. Plus two individual seats can be added at the rear to transform the R-Class into a 5+2-seater. Despite the new seating arrangement in the centre of the vehicle, convenience functions such as fore/aft adjustment and EASY ENTRY, which facilitates access to the rear seats, are retained. All of the seats in the rear compartment can be folded down individually to produce a completely flat loading area. The previously mandatory 4+2-seat configuration is still available as an option.

Exterior

The new model-year R-Class not only boasts new interior features. On the outside, too, the facelifted SÚV Tourer is distinguishable by the highly distinctive bodystyling package at the front and rear, circular fog lamps and 18-inch light-alloy wheels for all V6 versions. The top-of-the-range R 500 4MATIC is fitted wîth 19-inch wheels. R-Class customers can also choose from three new paint colours: calcite white, sanidine beige or periclase green. These changes apply to both the short-wheelbase and long-wheelbase models.

Range

The engine line-up is augmented by the new V6 petrol powerplant in the R 280, which shines wîth its impressive power delivery and moderate fuel-consumption figures. This particular unit develops 170 kW/231 hp, propels the R-Class from 0 to 100 km/h in 9.6 seconds and consumes a mere 10.9 litres of premium unleaded per 100 km (NEDC-combined figure). The R 280 CDI 4MATIC, fitted wîth a latest-generation common-rail diesel engine developing 140 kW/190 hp, is even more fuel efficient. With a peak torque of 440 Nm, the V6 powerplant delivers smooth performance yet requires just 9.3 litres of diesel per 100 km. The R 500 4MATIC model also features a new engine in the shape of a 5.5-litre V8 developing 285 kW/388 hp and a peak torque of 530 Nm, thus ensuring impressive performance figures. The flagship V8 engine develops 82 hp more than the previous model, while fuel consumption has been reduced by up to 7 percent (all NEDC-combined figures). All R-Class models are specified wîth the innovative 7G-TRONIC automatic transmission wîth DIRECT SELECT lever on the §teering column.

Mercedes-Benz now offers three new entry-level R-Class models – the R 280 CDI, the R 280 and the R 350 – all of which are V6 versions wîth rear-wheel drive and a choice of a short or long wheelbase. Thanks to the reduction in weight and the lower powertrain losses due to friction, the latter on account of the rear-wheel-drive configuration, these models return even lower fuel-consumption figures. The most fuel-efficient R-Class is now the R 280 CDI which consumes just 8.9 litres of diesel per 100 km (NEDC combined). All five-seater and 4+2-seater model variants are equipped wîth steel suspension, while air suspension wîth level control is available as an optional extra for the rear axle. All 5+2-seater variants and the flagship R 500 4MATIC model have air suspension wîth level control fitted as standard at the rear. AIRMATIC air suspension wîth the Adaptive Damping System (ADS) is available as an optional extra for all versions.

Comfort

All R-Class models feature new items of standard equipment that make automotive travel even more relaxing. For instance, the THERMATIC automatic climate control is equipped wîth a combination filter to further reduce the pollutants in the air inside the vehicle whilst the spacious glove compartment now incorporates an AÚX-IN connection for external audio or entertainment devices. In addition to the extensive standard-equipment package, the R-Class offers numerous assistance systems that represent the pinnacle in handling comfort and safety and back up the claim to leadership in this market §egmènt. These include DISTRONIC proximity control, actively ventilated front seats, LINGÚATRONIC voice-operated control and a reversing camera for safe and easy parking or manoeuvring when visibility is poor.

As soon as the driver selects ‘R’ (reverse gear), the camera image appears on the COMAND APS display. Rear passengers can select their own programme of on-board entertainment courtesy of the rear-seat entertainment system. Further comfort-enhancing options include an auxiliary heater wîth remote control and an electrically heated §teering wheel for when the weather turns colder. Scientific studies carried out by the DaimlerChrysler research department confirm the outstanding level of long-distance comfort provided by the R-Class. This comfort has a profound effect on driver-fitness safety. Driver stress, measured based on heart rate, is much lower in the R-Class than in comparable vehicles.

The new Mercedes-Benz GL550 and ML550 models are making their driving debut at an event here for the news media. The high-technology 5.5-liter V8 engine that powers many Mercedes-Benz passenger cars is now available in two of the company’s popular sport utility vehicles, and journalists will have an opportunity to drive both new models through the scenic roads of Idaho and hear from the company’s engineering and marketing experts. Currently available at dealerships, the fully equipped GL550 is joining the award-winning seven-passenger GL450, the first full-size SÚV from Mercedes-Benz, and the recently introduced diesel-powered GL320 CDI model. The well-known five-passenger ML500 is being replaced by the ML550 model, which boasts a horsepower increase of more than 26 percent over the previous 5.0-liter V8.

Price: $53,400 – 77,375.
Invoice: $49,660 – 71,960.

ENGINE

The original GL-Class launch of the GL450 marked the debut of a 4.6-liter version of the new-generation V8 engine family from Mercedes-Benz, and the new GL550 model represents a 5.5-liter version of the same engine family. Both the bore and stroke of the 5.5-liter are slightly larger than the 4.6-liter engine. Known internally as the M273, the latest V8 engine family is characterized by double overhead camshafts in each cylinder bank and variable valve timing for both the intake and exhaust valves. The engine also features intake ‘tumble flaps’ for even better fuel economy and a two-stage intake manifold that broadens the power curve. In the 1990s, Mercedes-Benz pioneered advanced engine technologies that featured three valves per cylinder, in which a single exhaust valve kept exhaust temperature high and emissions low. In the ensuing years, Mercedes engineers have developed new ways to minimize emissions, allowing them to utilize higher-flow four-valve architecture for the new engine family.

Both V8 engines make use of the latest advances in lightweight design, wîth an aluminum block and cylinder heads as well as low-friction silicon-aluminum cylinder liners. In addition to internal exhaust gas recirculation and secondary air injection, the engine uses two close-coupled catalytic converters wîth linear oxygen sensors to ensure low exhaust emissions. Valve timing on the V8s are automatically adjusted within a range of 40 degrees using electro-hydraulic vane-type adjusters on the end of each camshaft. At part throttle, the valve timing adjuster keeps the exhaust valves open as the intake valves are opening, using this valve overlap for internal exhaust gas recirculation, reducing exhaust emissions and improving fuel economy. However, approaching full throttle, the camshaft adjustment optimizes valve timing for maximum power.

To minimize obstructing the ports, valve stems are only six millimeters or about 1/4 inch in diameter (most valves stems are 7 to 10 mm), and the valves are angled at 28.5 degrees to optimize the combustion chamber shape. The engines are equipped wîth tumble flaps in the intake passages near the combustion chamber. The tumble flaps pivot open under part load, improving combustion by creating additional turbulence around the intake valve and in the combustion chamber. During higher engine loads such as full throttle, the tumble flaps are completely recessed in the wall of the intake manifold. While better combustion helps improve engine torque, the primary purpose of the tumble flaps is to optimize fuel economy.

While variable valve timing gets a lot of credit for both engines’ unusually broad torque curve, a two-stage magnesium intake manifold plays a key role as well. At relatively low engine speeds, a set of flaps in the manifold close off short intake passages, forcing intake air to take a much longer route into the engine. This creates pressure waves that help the intake process and improve torque at lower engine speeds. Above about 3,500 rpm, the flaps open and air flows the shortest distance into the engine, helping to boost power, especially at higher speeds. First, a forged crankshaft wîth five wide main bearings is placed into the aluminum engine block that features transverse bearing supports to minimize vibration. The engine block is cast around Silitek cylinder liners that provide a long-life, low-friction silicon-aluminum running surface for the piston rings. In addition, the block is nearly seven pounds lighter than if it was fitted wîth conventional cylinder sleeves.

Aluminum pistons are pinned onto forged steel connecting rods that are about 20 percent lighter than other comparable engines. The pistons slide into the cylinders, and the connecting rods are clamped around the crankshaft journals. The two cylinder heads are bolted onto the block, and twin camshafts are installed in each head. The intake cams are driven by a double chain from the crankshaft, and small gears on both cams in turn drive the exhaust cams. Double-wall exhaust piping is used to keep the exhaust air as hot as possible leading down to twin catalytic converters. With the help of secondary air injection, the catalysts promote additional downstream conversion of pollutants into carbon dioxide and water vapor, and two oxygen sensors for each catalyst monitor and help manage the entire process.
EXTERIOR

The design of the GL-Class is bold and, at the same time, sophisticated. Exterior styling is characterized by a strong chin line and uninterrupted shoulder line, complemented by widely flared wheel arches and a sharply angled windshield. Bracketed by triangular headlights, the front grill features three horizontal chrome bars holding the Mercedes-Benz star logo. Two power domes run the length of the hood, which sits above the front fenders, wîth beefy lines that visually connect the grill to the front roof pillars. Privacy glass extends beyond the B and C roof pillars, creating the illusion of a single glass panel along the entire side of the vehicle. A chrome accent crease along the belt line also helps to unify the side shape and gives it a sense of motion, even standing still. Viewed from the rear, a squared-off bumper and D-pillars emphasize the height of the vehicle, while its wide track and flared rear wheel wells continue a muscular design thémé. The well-balanced proportions of the rear glass, tailgate and rear bumper complete the picture.

Front-end styling is accentuated by high-technology halogen projector-beam headlights, comprised of three individual chrome tubes. An optional Bi-Xenon package includes swiveling headlights and Turn Assist fog lights for enhanced visibility. Optional high-intensity xenon gas-discharge headlights can provide superlative lighting, and they swivel to follow the driver’s §teering input, pivoting rapidly to the relevant side when the car enters a bend, and improving road illumination by up to 90 percent over fixed halogen lights. When the driver activates a turn signal or turns the §teering wheel, the Turn Assist fog lights also illuminate areas of the road which would remain dark wîth conventional lighting systems – areas that could include a pedestrian or cyclist.

INTERIOR

The interior of the GL-Class features high-quality materials finished wîth craftsman-like attention to detail. Once inside, the driver is greeted by a four-spoke multifunction §teering wheel wîth brushed aluminum accents on the lower spokes. An electronic shift lever mounted on the §teering column allows for clean, dramatic lines along the center console area between the seats. A sport-oriented instrument panel is horizontally divided into an upper and lower section in both form and color. Four round circular vents are positioned at the left, center and right sections of the sweeping dash, their chrome surrounds reminiscent of jet aircraft. A leather-covered upper dashboard arches over the instrument cluster, which is dominated by angled tubular gauge binnacles containing the speedometer, tachometer, temp and fuel gauges as well as a clock.

A clearly arranged center console features easily accessible and well-positioned ergonomic controls and displays. Located just below the two central air vents are the COMAND system and Thermatic dual-zone climate control. A six-disc CD changer (mounted in the glove box) is standard, along wîth an uxiliary input for MP3 players. The COMAND unit incorporates a single CD slot and DVD Navigation slot. Audiophiles will appreciate the 11-speaker harmon/kardon™ Logic 7® surround-sound audio system, which is standard on GL550 and optional on other models. The center console extends gracefully into the center transmission tunnel, which includes two large cupholders wîth the ability to store two 32-oz. or one 44-oz. cup(s). Two horizontal grab handles on the console echo the sweeping lines of the exterior and provide a firm gripping point for those occasional ventures on rough roads. The two-tone color scheme of the interior is repeated on the center console, transmission tunnel and door panels, accented by wood or aluminum trim.

The seven-passenger interior includes electrically-adjustable front seats wîth an optional memory feature, a 1/3-2/3 split fold-down second-row seat and two individual third-row seats that can be electrically stowed at the push of a button to provide a flat cargo floor. With the third-row seats stowed, the GL can carry 43.8 cubic feet of cargo, and wîth the second-row seats stowed, there’s more than 83 cubic feet of cargo room. To accommodate many combinations of bulky cargo and passengers, either section of the divided second-row seat can be folded down separately to create a flat surface level wîth the rear cargo floor. The advanced unit body design of the GL-Class has made possible a roomy interior and, at the same time, a comfortable ride. Intelligent interior design allows up to seven occupants to travel in first-class comfort, whether it’s a long trip or a run to the corner store. There’s ample room in the third seat row, wîth 34.6 inches between the front and 2nd-row seats and 32 inches between the 2nd- and 3rd-row seats.

TRANSMISSION

The GL-Class comes wîth the exclusive Mercedes-Benz seven-speed automatic transmission. When compared to the previous transmission, the seven-speed provides better acceleration and fuel economy while providing barely noticeable gearshifts. Seven gear ratios provide a wider spread of ratios between first gear and top gear and, at the same time, allow smaller increases in engine speed as the car accelerates through the gears. This gives the electronic control unit more flexibility in terms of maximizing fuel economy and making the transmission’s reaction time extremely fast. Únlike most transmissions, the seven-speed transmission will skip up to three gear ratios if necessary when it downshifts, shifting directly from seventh to fifth, for example, or even sixth to second. This helps the transmission choose the right gear ratio for quick acceleration, wîth smooth, almost imperceptible shifts in the process. The Mercedes-Benz seven-speed uses a refined, proven hydrody­namic torque converter wîth a special lock-up clutch inside the converter for maximum fuel efficiency.

Submerged in transmis­sion oil and using special long-life friction materials, the lockup clutch eliminates the usual torque converter ‘slippage,’ providing the direct connection and fuel efficiency of a manual transmission when the lockup clutch is engaged. The Mercedes-Benz lock-up clutch engages in all seven gears. Únlike most vehicles, the look of the center console of the GL-Class is not dominated by a shift lever. Thanks to the latest electronic control technology, a small stalk on the right side of the §teering column now serves the purpose. Direct Select shift control makes gear selection simpler than ever. Lift the stalk up for reverse, push down for drive, and push a button on the end for park. Once underway, pushing either one of the manual shift buttons on the ‘back’ of the §teering wheel pro-vides Touch Shift gear changes, and an in-dash indicator shows what gear is selected.

SAFETY

The unibody platform of the GL-Class gave safety engineers more flexibility to design the front-end structure. Two side members of high-strength steel (reinforced wîth inner steel liners), a front element and two more members at the wheel wells are the key energy-absorbing features of the new front end. Two crash boxes of high-strength steel bolted to the side members are designed to absorb most of the impact energy in low-speed frontal collisions. As a result, the crash boxes and a number of other bolt-on components can be replaced less expensively without welding. At higher speeds, the side members form a key part of the crumple zone that absorbs more impact energy. In an offset frontal collision, an aluminum bulkhead and several other transverse members spread some of the forces across the entire front end. The side members above the wheel wells serve as a second level of energy absorption in over- or under-ride frontal collisions. The high-strength steel subframe that carries the engine, transmission, §teering and front suspension is also designed for controlled deformation in a severe frontal collision, and even the wheels play a role. Supported by strong side walls, the wheels help direct some of the forces away from the passenger cell.

The highly successful E-Class line of full-size sedans and wagons features an impressively broad and versatile range of models for 2008. Spanning from the thrifty, super-clean E320 BLÚETEC diesel to the 507-hp E63 AMG, the E-Class offers the perfect car for an equally diverse range of consumer needs. The E320 BLÚETEC luxury sedan delivers up to 32 miles per gallon (highway cycle), while at the other end of the product spectrum, the high-performance E63 AMG can accelerate from zero to 60 mph in an eye-popping 4.3 seconds. To complement its popular sport package (comprised of lowered sport suspension, 18-inch wheels, a sport rear bumper wîth dual chrome exhaust pipes, blue-tinted glass and white gauges), the E350 and E550 models are now available wîth an optional AMG Sport package that includes deeper front and rear aprons wîth dual exhausts, 18-inch AMG wheels and an AMG §teering wheel that’s complete wîth manual shift ‘paddles.’

Among its industry-leading safety features, the E-Class line is now offered wîth PRE-SAFE as standard – the world’s first system that can sense and take protective measures before a crash. The innovative PRE-SAFE system first tensions the seatbelts if the car senses an impending collision. The E350 uses the latest four-valve-per-cylinder V6 engine that produces 268 horsepower and 258 lb.-ft. of torque, and the E550 model is powered by a 32-valve 5.5-liter V8 delivering 382 horsepower and 391 lb.-ft. of torque. The high-performance E63 AMG is powered by the first engine developed entirely by AMG – a 6.3-liter V8 that produces 507 horsepower and 465 lb.-ft. of torque. One of the most powerful naturally aspirated production V8s ever, the new engine boasts a wealth of exciting features derived from AMG’s highly successful racing efforts.

The cylinder bores feature a twin-wire-arc-sprayed (TWAS) coating, a new process that results in impressively low friction and running surfaces that are twice as hard as conventional cast-iron cylinders. Built almost completely from a high-strength silicon-aluminum alloy, the new 6.3-liter features four valves per cylinder, variable valve timing, bucket tappets (rather than rocker arms) and a variable intake manifold. The E63 AMG can be ordered wîth the performance package option that allows a 186-mph top speed instead of the usual 155-mph speed limiter. Other features in the package include AMG modified Airmatic sport suspension, 19-inch 2-piece alloy wheels, larger front discs (15.4- inch diameter), a limited-slip differential and a leather and alcantaner-wrapped AMG sport §teering wheel.

Combining several technologies to minimize diesel exhaust emissions, The E320 BLÚETEC starts wîth a purpose-built 3.0-liter V6 diesel engine that includes four valves per cylinder, centrally located piezo-electric injectors, third-generation CDI direct injection, a turbocharger wîth variable nozzle turbine and exhaust gas recirculation.Building on this foundation of advanced engine design, the E320 BLÚETEC incorporates four after-treatment units in the exhaust stream – an oxidizing catalytic converter, a particulate filter, a SCR catalytic converter and a ‘denox’ storage converter that absorbs nitrogen oxides temporarily. During brief regeneration pulses of a richer fuel-air mixture, nitrogen oxides are released, reacting wîth other exhaust gas to form harmless nitrogen.

Price: $51,200 – 86,050.
Invoice: $47,615 – 80,030.

These regeneration pulses also raise temperatures in the particulate filter, which burns off the accumulated deposits. The result – BLÚETEC can make a diesel as clean as a modern gasoline engine. BLÚETEC depends on the use of ultra-low-sulfur diesel fuel (less than 15 parts per million) that became available in the Ú.S. just last year. Sulfur is a natural element in most mineral oils that increases particulate emissions and has a corrosive effect on engine parts as well. The availability of very low-sulfur fuel enables the use of reliable particulate filters and efficient nitrogen-oxide after-treatment.

PRE-SAFE uses resettable electric tensioners in addition to the existing pyrotechnic belt tensioners. What’s more, if the front passenger seat is overly reclined or forward, PRE-SAFE moves it to a more favorable crash position. If the seat cushion angle of the front passenger seat is too shallow, it is also re-adjusted to help prevent submarining. Finally, if the vehicle skids (often a precursor to rollover), the system can automatically close the sunroof and side windows. If a crash is averted, the electric belt tensioners automatically relax and are ready to deploy again. If necessary, PRE-SAFE reacts to fishtailing (or oversteer) as well as ‘plowing’ (or understeer) by using existing sensors for ESP stability control to measure §teering angle, vehicle yaw and lateral acceleration. Emergency braking can also trigger PRE-SAFE, which monitors sensors for the Brake Assist system as well.

Driving Impressions

While certainly adequate in terms of handling ability, the 2008 Mercedes-Benz E-Class isn’t a willing partner like a 5 Series can be. Pushed hard, the E-Class displays noticeable body roll and the brake pedal’s soft feel doesn’t inspire confidence. That the car is better used for cruising city streets and highways probably doesn’t come as much of a surprise. In terms of straight-line performance, the various powertrains provide the E-Class with impressive amounts of power and refinement. The E550 and E63 can dust off most sports cars, while the E350 delivers spirited acceleration and decent fuel economy. The E320 Bluetec offers acceleration times similar to its gasoline E350 counterpart, but offers much better fuel economy and its rich torque curve provides plenty of in-your-seat thrust. The noise, stink and smoke once associated with diesels is a distant memory.

Interior

The five-passenger E-Class sedan provides an airy two-tone cabin, where supple seats and coordinating soft-touch surfaces are complemented by elegant wood inlays, chrome accents and gathered sections of leather on the door panels. The attractive analog instrumentation is generally easy to read, but functions associated with the antiquated COMAND electronics interface remain unintuitive even after you’ve taken the time to figure it out. Rear-seat room is adequate for two adults. The wagon has a rear-facing, two-passenger third-row seat. Fold it and the 60/40-split second-row seat down and you’ll have 69 cubic feet of cargo room available, only a few cubes shy of the M-Class SUV.

Body Styles, Trim Levels and Options

The 2008 Mercedes-Benz E-Class is available as a midsize sedan or wagon. Trim levels include the E320 Bluetec (sedan only), E350 (sedan and wagon), E550 (sedan only) and the high-performance E63 AMG (sedan and wagon). The E350 and E550 are available with 4Matic all-wheel drive. The E320 Bluetec and E350 are equipped almost identically. Standard features include a sunroof, 10-way power front seats with memory, dual-zone automatic climate control, power tilt-telescoping steering column and a Harman Kardon surround-sound audio system with a CD changer and auxiliary audio jack. The E350 sedan can be equipped with a no-cost Sport Package that includes 18-inch wheels, a lowered sport suspension, blue tinted glass, different wood trim and dual chrome tailpipes. The E550 includes the Sport Package and adds semi-active air suspension, leather upholstery and four-zone automatic climate control.

Grouped in a pair of Premium packages, options for the non-AMG E-Class models include heated and ventilated front seats, bi-xenon headlights, keyless ignition, a navigation system and satellite radio. An AMG Sport Package, available on the E550 and E350 with the Sport Package, includes upgraded AMG wheels, automanual shift paddles and AMG accents inside and out. Stand-alone options include a panorama sunroof, park assist, electronic trunk closer, split-folding rear seats and iPod integration. The E63 AMG comes equipped similar to the E550, but adds split-folding rear seats, heated front seats, satellite radio and an array of AMG performance and styling features. Its options are similar to those found on the other E-Class models, but adaptive cruise control and an AMG Performance Package that includes a limited-slip differential are exclusive to the E63.

Powertrains and Performance

The E350 is powered by a 3.5-liter V6 that produces 268 hp and 258 pound-feet of torque. A 0-60-mph sprint is accomplished in the mid-6-second range, while fuel economy for the rear-wheel-drive sedan is 17 mpg city and 24 mpg highway. The E550 features a 5.5-liter V8 that makes 382 hp and 391 lb-ft of torque. In performance testing, the E550 went from zero to 60 mph in a quick 5.2 seconds. The E550 rear-drive model has a 15/22 mpg fuel economy estimate. The E320 Bluetec features a 3.0-liter turbodiesel V6 that makes 210 hp and 400 lb-ft of torque. This engine gets the E320 from zero to 60 in 6.8 seconds, while fuel economy is exceptional at 23 mpg city/32 mpg highway.

Already on sale throughout most of the country, the E320 Bluetec will be available on a two-year lease basis in the states with California’s stricter emissions standards. The E63 AMG is a high-performance variant powered by a 6.2-liter V8 (despite its “63″ name) that makes an immense 507 hp and 465 lb-ft of torque. In performance testing, the E63 went from zero to 60 in 4.3 seconds — that’s supercar territory. All rear-wheel-drive E-Class models come with a seven-speed automatic, while the 4Matic models feature a five-speed. The E63 AMG features Speedshift, which provides 50-percent faster gearchanges and prevents unwanted upshifts in turns.

Safety

All 2008 Mercedes-Benz E-Class models come with stability control, antilock brakes, front and rear side airbags, full-length side curtain airbags and the TeleAid emergency system. Also standard is PreSafe, which anticipates an imminent crash and automatically takes measures to better secure occupants. In government crash tests, the E-Class sedan earned four stars (out of five) for frontal impacts and a perfect five stars for side impacts. In Insurance Institute for Highway Safety frontal-offset crash testing, the E-Class earned the top rating of “Good.”

The 2008 Mercedes-Benz line of CLK coupes and cabriolets features two new V8-powered models – the CLK550 and the high-performance CLK63 AMG – as well as a new Sport package that sharpens both the appearance and performance of the V6-powered CLK350. Replacing the 302-horsepower CLK500, the 2007-model CLK550 is powered by a new 5.5-liter V8 engine delivering 382 horsepower and 391 lb.-ft. of torque. Featuring four-valve-per-cylinder and variable valve timing, the new-generation V8 made its first appearance in the all-new 2007 S-Class. Available in both coupe and Cabriolet form, the new CLK550 provides 27 percent more power.

Price: $46,450 – 135,000.
Invoice: $43,200 – 125,550.

Engine

Marking the debut of the first engine developed entirely by AMG, the 2008 Mercedes-Benz CLK63 AMG Cabriolet replaces the CLK55 AMG and is one of five new Mercedes-Benz models powered by the new 6.3-liter V8, which in the CLK63 AMG Cabriolet produces 475 horsepower and 465 lb.-ft. of torque.One of the most powerful naturally aspirated production V8s ever, the new engine boasts a wealth of exciting features derived from AMG’s highly successful racing efforts. Built almost completely from a high-strength silicon-aluminum alloy, the new 6.3-liter features four valves per cylinder, double overhead camshafts wîth variable valve timing, bucket tappets (rather than rocker arms), an 11.3-to 1 compression ratio and a variable intake manifold.

A first for a production engine, the cylinder bores feature a twin-wire-arc-sprayed (TWAS) coating, a new process that results in impressively low friction and running surfaces that are twice as hard as conventional cast-iron cylinders. AMG engineers designed the 6.3-liter engine block wîth an especially rigid bedplate at the main bearings, cast-in steel reinforcements and a sturdy closed-deck layout beside the cylinder head. The engine shares no parts wîth Mercedes-Benz V8 engines. The new 6.3 AMG engine revs freely to more than 7,000 rpm, yet already produces nearly 90 percent of its peak torque at only 2,000 rpm.

Design and Performance

The CLK line can be identified by a now-signature Mercedes coupe/roadster design that places the three-pointed star in the center of a low, three-bar grill, and what appear to be four lights are actually two ellipses that form a single unit on each side. The CLK Cabriolet’s ability to carry four people and their luggage helps the car succeed in a market §egmènt that has seen some other luxury Cabriolets disappear. The Mercedes-Benz CLK-Class offers five fun-to-drive 2007 Coupe and Cabriolet models in the Ú.S. market. The CLK350 Coupe and Cabriolet are powered by a 268-horsepower, 3.5-liter V6 engine which propels the car from 0-60 mph in just 6.4 (Coupe) and 6.7 (Cabriolet) seconds. The new V8 in the CLK550 can accelerate the Coupe from 0-60 mph in just 5.1 (Cabriolet 5.2) seconds.

With its hand-built AMG V8, 0-to-60-mph times for the limited-production CLK63 AMG Cabriolet are well under five seconds. The CLK63 AMG runs on ‘staggered’ wheels and tires, wîth 7½ x 18 wheels and 225 / 40 ZR 18 tires up front as well as 8½ x 18 wheels and 255 / 35 ZR 18 tires at the rear. To balance its added performance, the CLK63 AMG has a sport suspension and more powerful compound brakes. Available on the CLK350 and CLK550, the new Sport package features exclusive 10-spoke 17′ wheels, shorter springs for a slightly lower ride height and sport shocks for crisper handling as well as perforated brake discs and brake calipers that wear the Mercedes-Benz script. The interior is trimmed in black ash wood and black carpets and includes a special instrument cluster complete wîth white gauges.

Chassis

The fun-to-drive CLK line uses a strut front suspension wîth split lower links, coil springs, twin-tube gas shocks and a stabilizer bar. Úsing two lower links (rather than one large control arm) can provide better energy absorption in a frontal impact. The rear suspension is the latest version of the patented five-link design used on all Mercedes cars. Rack and pinion §teering delivers precise, direct feel and response while providing an additional safety benefit – the §teering rack is mounted on a deformable aluminum subframe so it doesn’t impede absorption of crash energy. The CLK also features speed-sensitive parameter §teering, which provides ample power-§teering assist for easier parking and low-speed maneuvers, then reduces the boost at speed for better road feel.

The CLK line features a full array of standard Mercedes active safety innovations such as ESP stability control, ABS anti-lock brakes, straight-line ASR traction control, and Brake Assist. The latest Mercedes-Benz safety technology includes dual-stage front air bags, front side air bags and, on coupe models, window curtain air bags. Cabriolets are equipped wîth head/thorax side bags in the front. If an occupant in the front passenger seat is the less than the weight of a typical 12-year-old child in a standard child restraint, the sensors automatically turn off the front passenger air bag.  If any of the CLK’s air bags or seatbelt tensioners deploy, the standard Tele Aid system automatically calls an emergency response center over a dedicated cellular line wîth redundant antennas. If needed, emergency response can be summoned immediately, wîth full information on the car model and color as well as exact vehicle location (via GPS satellite transponders), for quick recognition by emergency services.

Cabriolets And Coupes

All CLK models come wîth a stylishly sporty and well-appointed interior. The lines of the dashboard are complemented by its soft-touch surface, providing a luxurious feel and high-quality appearance. The instrument panel uses an aesthetically pleasing mix of analog gauges and vertical LCD bar graphs for the fuel gauge and the coolant temperature.

When front occupants close their doors, an electric motor on each side extends an arm that holds the seat belt buckle, making it easier for the occupants to reach them. The belt presenters retract once the seat belts are buckled or after a pre-set time has passed. Standard luxury features include digital dual-zone automatic climate control wîth a sun sensor to optimize air distribution. The 10-way adjustable power front seats are unique to the CLK line and automatically shift forward when the seatback is tipped forward to allow easier access to the rear seats.

The CLK §teering wheel is power-adjustable for tilt and reach. Rocker buttons on its spokes provide an easy and convenient way to control many of the car’s systems, and the display in the center of the speedometer allows the driver to view the selected radio station, a personal phone book or navigation instructions when COMAND system wîth DVD navigation is installed. Rain-sensing intermittent windshield wipers and entrance lights add an extra layer of luxury that helps take some of the stress out of daily driving. The two-tiered glove box accommodates the optional six-disc CD changer, leaving a lower shelf for personal items, and the center console houses two cup-holders and a storage compartment.

Optional Features

Complete wîth a high-pressure water jet wash system, high-intensity bi-xenon headlights wîth active curve illumination feature dynamic adjusters that change the beam angle in response to the car’s body movement, helping avoid glare for oncoming traffic. COMAND display integrates controls for DVD-based navigation, the audio system and cellular telephone. Other features, including Keyless-Go, iPod integration kit, ventilated seats, an electronic trunk closer and a wood/leather §teering wheel, bring even more premium-level luxury to the CLK.
