Mercedes-Benz Unveils Facelifted SL ROADSTER for 2009

Mercedes-Benz released the first official photographs today of its facelifted 2009-model SL roadster, the iconic sports car that's a direct descendant of the legendary 300SL 'Gullwing' of the 1950s. Planned for a public debut in March at the International Motor Show in Geneva, the new SL features dramatic new styling with fenders that incorporate bold new headlamps and modified gill-type air outlets behind the front wheels. A redesigned hood with twin power domes and a wider, single-bar grille emphasizes the width of the body and makes a symbolic visual connection to the famous 1954 300SL. Standard AMG body styling further enhances the aggressive new appearance. The 2009 model year SL line-up is scheduled to make its showroom debut this Spring.

Larger side mirrors reveal built-in arrow-shaped turn signals. At the rear, the SL looks sportier than ever, with a new air diffuser in the bumper that adds a motorsports touch, as well as trapezoidal exhaust tips that emphasize its width and suggest all the power that's on tap.

Center-stage in the cockpit are a new-design three-spoke steering wheel and a restyled instrument cluster with eye-catching red tachometer and speedometer needles that swing to the max position and back to zero whenever the ignition is turned on.

AIRSCARF Around the Head and Neck
The 2009 Mercedes-Benz SL roadster is now available with AIRSCARF, an innovative feature that can extend the open-air driving season into the cooler months. Another technological first from Mercedes, AIRSCARF is an extra heating system built into the driver and passenger seats. At the touch of a button, warm air flows from vents in the head restraints, acting as an invisible scarf around the head and neck.

Testing revealed that warming just a relatively small area around the neck dramatically improves comfort in cooler weather. The AIRSCARF neck-level heating system blows warm air from the head restraints of the driver and passenger seats, allowing occupants to cruise comfortably with the retractable hardtop open in colder weather. AIRSCARF uses a heating element made primarily of barium titanate, which heats up in a matter of seconds when an electrical current is applied.

Its electrical resistance jumps once it's heated, reducing power use – engineers call this balance 'Positive Temperature Coefficient' or PTC for short. The PTC heater is only a few inches in size, allowing it to hide inside the SL seatback. Aluminum fins on the heater help transfer the heat to the air, and a small fan pushes the heated air through the vents in the head restraint.

Optional on the SL550 and standard on the SL600 and SL65 AMG models, the AIRSCARF neck-level heating system even compensates automatically for changes in air temperature and vehicle speed. AIRSCARF comes with a three-speed switch and an electronic control module that monitors data from the speedometer as well as from inside and outside temperature sensors. AIRSCARF automatically adjusts the fan speed based on this information, and at the same time, the switch can override the automatic settings.

New Audio Technology


Bluetooth-enabled cell phones will work hands-free – even with the phone in a pocket or purse, the audio is automatically muted when a call is made or received, and callers are heard over the audio system speakers. In addition, phone address book info can be displayed by the COMAND system.

From Coupe to Roadster in 16 Seconds


At the push of a button, the SL's retractable hardtop can be fully opened or closed in just 16 seconds, transforming the car from a quiet, weather-tight coupe to a top-down, open-air convertible. A hydraulic pump and 11 computer-controlled hydraulic cylinders power the system, and roof operation is controlled by a switch on the center console. A clever folding design allows for a surprisingly large cargo area of 7.2 cubic feet when the top is down. With the top up, the trunk holds 10.2 cubic feet.

The World's Safest Convertible


Widely acclaimed as one of the world's safest convertibles, the SL provides sports car performance with 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 with the world's first automatic roll bar. Normally part of the interior's rear-compartment surround structure, the padded, leather-covered bar pops up, locking in place in a third of a second if sensors detect an impending rollover. The driver can also raise and lower the bar by a switch on the console.

Major Stopping Power for All SL Models

ABC Active Suspension Gives Cat-Like Agility

The SL chassis uses a fully independent, double-control-arm front suspension and the patented Mercedes-Benz five-link rear suspension. All SL models come with second-generation Active Body Control (ABC), the Mercedes-Benz active-suspension technology that virtually eliminates body roll in cornering, squat under acceleration and dive during braking.

Mercedes-Benz engineers use ABC's interplay of hydraulic, electronic and mechanical parts to reduce body roll by 68 percent (compared to the same vehicle with a conventional suspension), providing the driver with needed feedback through the vehicle chassis. A ‘Sport' switch on the center console can make it 95 percent reduced roll, along with tighter shock damping. Active suspension solves the usual tradeoff between ride comfort and handling precision, so SL roadsters offer excellent comfort and league-leading handling.

Seven-Speed Automatic for the SL550

While the V12-powered models use a modified five-speed automatic transmission, the SL550 features a seven-speed automatic. This transmission improves acceleration and enhances fuel efficiency, while gear changes are barely noticeable, especially in the higher gears. The seven-speed shortens 0-to-60 mph time and allows significantly quicker acceleration for highway passing. Úsing seven gears allows individual gears to be spaced closer together while providing a larger overall spread between the lowest and highest gear.

Mercedes-Benz will continue its long tradition of producing legendary sports cars when it launches the new-generation SL-Class in spring 2008. The world's most successful premium roadster in its class features a new design with the emphasis firmly on sportiness and effortless assurance. These traits are also reflected in the handling qualities of the two-seater model, which now delivers even more athletic performance thanks to the new direct-steer system as well as offering enhanced comfort and safety.

The SL 350 is powered by a newly developed, extremely high-revving sports engine boasting an impressive output of 232 kW/316 hp yet returns a fuel consumption figure that is 0.4 litres per 100 kilometres lower than that of its predecessor (NEDC). The SL range will now feature two six-cylinder models in the shape of the SL 350 and the new SL 280 (170 kW/231 hp) as well as the familiar SL 500 with a V8 engine and the top-of-the-range SL 600 with a V12 powerplant. The Mercedes sports car extends its lead in the safety stakes courtesy of bi-xenon headlamps, included as standard, and the Intelligent Light System whose light functions are designed specifically for typical driving situations. Further new features on board include AIRSCARF neck-level heating. This system - invented by Mercedes-Benz and available as an optional extra - enhances comfort when driving with the roof down, extending the roadster season until well into the winter months. SL passengers are kept informed and entertained by the standard-fit COMAND multimedia system, which has also been fully redeveloped and features additional functions.



When it came to developing a concept and design for the new-generation SL Class, the Mercedes-Benz engineers set out with the aim of accentuating the Roadster's sporty attributes even more strongly than before. This aspiration is reflected in the new front-end design featuring as its centrepiece a wide and, therefore, very dominant radiator grille whose V?shape symbolises sporty virtues such as forwards thrust and performance potential.

A horizontal louvre makes the radiator grille appear wider and, in doing so, emphasises the powerful aspect of the SL's front end, making it seem surprisingly new yet also very familiar. By using expressive stylistics in this way, the Mercedes designers are able to forge a link with the SL's history and create a front-end design that is reminiscent of the earlier SL Roadster models, which also expressed their poise and assurance through wide, very distinctive radiator grilles. Hence the front-end design of the new-generation SL shows Mercedes-Benz taking the styling of the legendary sports car to the next level.



These classic design features drawn from five decades of roadster tradition are in stylish harmony with new elements of the modern Mercedes design idiom, including the distinctive V-shape of the front section and, above all, the headlamps, which are drawn deeply into the flanks, thus further emphasising the impression of breadth at the front end. As well as giving the SL a highly contemporary look, this striking headlamp design also sees the Roadster continuing its traditional role as a trendsetter. Just like its predecessors, the new?generation SL features a front-end design that will serve as a template for future Mercedes passenger cars.

At the rear, too, the new-generation SL demonstrates its sporty nature even more clearly than before. This is achieved above all by a new, diffuser-look bumper which adds a motorsport touch. In conjunction with the equally new trapezoidal exhaust tailpipes this design element emphasises the width of the body, further symbolising the power just waiting to be unleashed by the roadster.
