The 429-hp 4.6-liter V-8 combines twin turbos and numerous advances to deliver more torque from less fuel, with cleaner emissions. Rapid-multispark ignition can fire up to four times per millisecond, while high-pressure Direct Injection can fine-tune fuel spray in 0.1 millisecond, reducing emissions, fuel consumption and noise. A lightweight diecast-alloy block, widely variable valve timing, reduced friction, and clever "on-demand'' ancillary components further boost efficiency.
The industry's first 7-speed automatic is smooth, responsive and efficient. A wide range of closely spaced ratios delivers the ideal response in virtually every driving situation, for relaxed cruising, quick acceleration, and thanks to two overdrive ratios, better highway fuel efficiency. Adaptive logic adjusts the shift points to match your driving style, while shift paddles on the steering wheel let you enjoy manual-style control anytime.
For more nimble, precise handling, virtually all components of the 4-wheel multilink suspension are made of rigid, lightweight aluminum. The semi-active Adaptive Damping System continually adjusts to driving inputs and the road surface, and can respond at each wheel in just 10 milliseconds to sharpen handling while the ride stays silky. Comfort and Sport modes let you tailor handling response and ride firmness to your present driving style.
Standard Torque Vectoring Brake technology provides additional control and precision in turns via targeted rear-wheel braking. If the vehicle's Electronic Stability Program (ESP®) detects understeer while cornering, the system applies the brake to the inside rear wheel, temporarily shifting torque distribution in favor of the outside wheel. This causes the vehicle to gently pivot in compensation, putting it on a line of travel, or vector, better suited to the turn.
A fuel-saving ECO Start/Stop system automatically shuts off the engine at stoplights and other idle situations. As soon as the driver lifts off the brake, the engine instantly restarts, for immediate acceleration response. The ECO Start/Stop system can also be shut off by the driver at any time.
A pair of paddles strategically positioned behind the upper steering-wheel spokes allows you to manually upshift and downshift the 7-speed automatic transmission with just a flick of your fingers.
Advanced, lightweight and highly efficient electromechanical power steering allows for more precise control of steering effort and feedback. Direct-steer automatically varies the steering ratio based on how far you turn the steering wheel. It provides quicker steering and lighter effort while parking while maintaining excellent directional stability and crisp feel at higher speeds.
Perforated and internally ventilated front brake discs help maintain maximum braking performance by better dissipating the heat of hard or repeated braking that can cause brake fade. The perforations are cast in place when the rotor is made, to prevent the creation of stress points that can occur during conventional cross-drilling. For more even and powerful braking force, the front discs feature large 4-piston calipers. Disclaimer
As gifted aesthetically as it is athletically, the SL draws an unmistakable line from history to the future. From the upright grille and central Star, the powerful contours of the long hood sweep past the cockpit into the an aggressively contoured tail. Advanced aerodynamics and LED lighting harmonize with elegant chrome-accented vents in the hood and fenders. And with its signature retractable hardtop, it's perfectly proportioned as both a sleek closed coupe or classic open roadster.
The Panorama roof opens up a whole new look, inside and out. Occupants enjoy an expansive view of the sky through a heat-reflecting transparent panel. A manual mesh sunshade helps limit the amount of sunlight entering the cabin.
Staggered-width alloy wheels and tires are wider at the rear for greater launch grip, and narrower up front for crisper steering feedback. The SL550's standard 18-inch wheels feature an alluring twin 5-spoke design with a bright silver finish, and they're fitted with high-performance tires. Disclaimer
Aggressively styled lower bodywork includes a deep front air dam with mesh intakes, along with aerodynamic sculpting of the side sills and rear valance.
Transform your SL from closed coupe to open roadster in about 16 seconds, the quickest hardtop in its class and perhaps the entire industry. With a single button on the console, the top folds into the trunk. The rear window pivots 180 degrees as the hardtop lowers, to help preserve cargo space with the top stowed.
Lavished in supple leather, hand-polished wood and a bounty of user-friendly technology, the SL550 cabin keeps its two occupants feeling coddled, connected and captivated. Classic round air vents and advanced controls and displays reflect two longstanding SL traditions: timeless style and ahead-of-its-time technology.
The sporty steering wheel features pronounced contours, thick padding and a Nappa leather-wrapped rim, putting the delights of precise handling literally in the driver's hands. Convenient multifunction controls do likewise while operating the most frequently used vehicle functions and the illustrated color menu display in the gauge cluster. Raised thumbrests are placed at the ideal "10 and 2 o'clock" positions, near the shift paddles.
A precise timepiece with timeless appeal, the optional analog clock is situated atop the finely stitched dashboard beneath its own sporty, arched hood.
Hand-polished Burl Walnut wood trim graces the console, dash and doors with its intricate grain, lending the cockpit a further air of refinement and exclusivity.
Hand-polished Black Ash wood trim adorns the console, dash and doors with its deep, dark grain, adding a dramatically modern aura to the cockpit.
The distinctively mottled grain of this hand-polished hardwood trim evokes a grand tradition of craftsmanship. Fitted to the console, dash and doors, its low-sheen finish brings a modern luster to its timeless warmth.
Genuine aluminum brings a sleek, high-tech feel to the console, dash and doors of the SL. Its crisp elegance reflects both the precision and advanced technology the cockpit brings to the driver's hands.
Engineered from road to roof not just as a convertible but as a Mercedes-Benz, the SL body structure enhances both occupant protection and handling precision. Composed virtually entirely from stamped, cast, chilled-cast, thermoformed and extruded aluminum, the body shell is nearly 300 lbs lighter than before yet 20% more torsionally rigid. The only structural steel in the body is the windshield frame, whose "tube-in-tube" pillars offer high strength with minimal vision obstruction.
Another Mercedes-Benz safety breakthrough, PRE-SAFE® can detect instability during certain vehicle maneuvers that suggest a collision or rollover is imminent. It can then tighten the seat belts, adjust the occupied passenger seat, and close the front side windows, all in an effort to better prepare the occupants in the moments before a collision. If no accident occurs, you simply readjust your seat, reopen the windows, and continue on your way. Disclaimer

The sophisticated restraint system includes front air bags with dual deployment thresholds, as well as innovative head air bags, plus thorax side-impact air bags and knee bags for both driver and passenger. Disclaimer
The first system of its kind, ATTENTION ASSIST® continuously monitors up to 70 different parameters of driving behavior, and can automatically alert the driver with both visual and audible warnings if it detects signs of drowsiness on long trips. Disclaimer
In 1989, Mercedes-Benz pioneered the pop-up roll bar, a significant advancement in convertible safety. When sensors detect an impending rollover, the dual roll bars of the new SL deploy in a third of a second to help preserve and protect occupant space. Disclaimer
Active Parking Assist helps you size up parallel-parking spaces as you drive by, using sensors in the bumper to determine if a spot can fit your car. It then expertly steers the car into the space while you control the brakes and gear selection. In any low-speed maneuver, PARKTRONIC's ultrasonic sensors in the front and rear bumpers help detect nearby objects within the system's field of view. Audible signals and illuminated displays in the cabin help you navigate tight spaces with confidence.
For added safety when backing up, the rear view camera shows a live view of the area behind your vehicle on the in-dash screen. Disclaimer
Bi-Xenon headlamps help deliver greater visibility than halogen headlamps because their brighter, whiter light is much closer to natural daylight. Active Curve Illumination swivels the beams as you steer, to help you see better into corners at night by increasing usable illumination by up to 90% over conventional fixed headlamps.
Adaptive Highbeam Assist uses continuous input from a camera to automatically vary the range of your headlamps, based on the distance to oncoming vehicles and to those ahead of you. It's engineered to maximize road illumination without creating glare for other drivers.
To help you negotiate tight turns, corner-illuminating front lamps shine toward the inside of the turn. Activated by turning the steering wheel or using the turn signals at low speeds, they're particularly useful in parking structures, suburban neighborhoods or when turning into driveways.
Bright white LED Daytime Running Lamps help increase the visibility of your vehicle to oncoming traffic by illuminating front lamps whenever the car is switched on. With long life and low energy consumption, the light-emitting diode (LED) technology is also used for the taillamps, including quicker-illuminating brake lamps. By offering drivers behind you more time to react, their stopping distance may be reduced by several feet, which could make a critical difference in a panic stop.
In the case of a rear impact exceeding a preset threshold, NECK-PRO® front head restraints move forward and slightly upward, reducing the distance between the head restraints and the heads of front-seat occupants. This action helps to reduce the possibility or severity of whiplash-type neck injuries.
Equipped with Emergency Tensioning Devices (ETDs) and belt force limiters, 3-point seat belts are arguably our most important passive safety feature. If a collision exceeds a preset threshold, the ETDs instantly remove slack from the seat belts. Belt force limiters allow a slight amount of give in the seat belts and reduce the peak seat-belt forces on the occupant.
The Tire Pressure Monitoring System (TPMS) can automatically detect a substantial loss of tire pressure in any wheel and alert the driver via a warning message in the multifunction display. The advanced TPMS can also display the numeric tire pressure for each mounted wheel.
Adaptive braking technology integrates a suite of advances. If you lift off the accelerator quickly, Predictive Brake Priming sets the pads closer to the discs for more immediate response when you apply the brakes. In the rain, Automatic Brake Drying periodically applies the brakes just enough to sweep water build-up from the discs. During uphill starts, Hill-Start Assist helps prevent unwanted rollback. And a brake HOLD feature can make long red lights or stopped traffic a little easier. Disclaimer
BAS® senses emergency braking via the speed at which the driver presses the brake pedal, and immediately applies maximum available power boost. By eliminating the delay caused by a common human tendency not to brake hard enough, soon enough, Brake Assist can potentially reduce the overall stopping distance. Letting up on the brake pedal releases BAS. Disclaimer
The Antilock Braking System (ABS) senses impending wheel lockup under heavy braking, and pumps the front brakes individually or the rear brakes together up to 30 times per second. By preventing wheel lockup, ABS helps preserve the driver's steering ability during hard braking. Disclaimer
This safety breakthrough first introduced by Mercedes-Benz continually monitors your driving inputs and the vehicle's motion to help keep it going in your intended direction, especially in corners and during evasive maneuvers. If it detects wheelspin, severe understeer (plowing), or oversteer (fishtailing), ESP® can brake individual wheels and reduce engine power to help bring the vehicle under control. Disclaimer
The SmartKey remote control integrates remote door locks and trunk opener, a removable valet key, and a remote panic alarm. Selective unlocking lets you unlock only the driver's door and fuel filler, or both doors plus the trunk and fuel filler.
Program your Mercedes-Benz to illuminate its exterior lights when you unlock it in darkness, to help illuminate a path to your vehicle.
MAGIC VISION CONTROL® features wiper blades with laser-cut holes that emit a highly precise spray of washer fluid directly in front of the moving wipers. The system eliminates the brief, vision-obscuring spray across the full windshield, and minimizes the overspray and runoff that can reach the passengers during top-down driving. And since the washer fluid reservoir, lines and even the wiper blades are heated, it's also extremely effective in cold weather.
Rain-sensing windshield wipers automatically adjust the intermittent wiper frequency based on the amount of rainfall.
The standard antitheft alarm system is armed automatically when you lock your Mercedes from the outside. It sounds the horn and flashes the exterior lights if a door, the trunk or the hood is opened without first unlocking the vehicle. You can also sound the alarm by pressing the red "panic" button on your SmartKey remote when you´re within range of your vehicle.
Supple, full-grain leather is hand-fitted to the seat surfaces and head restraints. Tradition meets technology in an innovative treatment that helps the leather reflect heat and better resist the sun's damaging rays.
Intuitive, seat-shaped controls help you and your passenger find your ideal seating positions with 12-way power adjustment, including cushion length, plus 4-way power lumbar support. A memory system for each seat recalls three stored seat positions with the touch of a button. The driver-seat memory also includes the power steering column and side mirror positions.
Extend your top-down driving enjoyment further into a cool evening or later into the season with the AIRSCARF® neck-level heating system. Vents beneath each head restraint deliver warmed airflow to your neck, head and shoulders, like a virtual scarf. With individual 3-stage temperature controls and airflow automatically adjusted to your driving speed, AIRSCARF means you don't have to put the top up just because the sun, or thermometer, has gone down.
For added convenience in the rain or with an armful of packages, you can fully open the trunk via a switch on the driver's interior door panel or a button on the SmartKey remote. Press a button on the driver's door or the underside of the trunk lid and it powers itself closed. A sensor automatically stops the lid if it detects an obstruction. A new, even easier feature, HANDS-FREE ACCESS, opens or closes the trunk with a wave of your foot under the rear bumper.
Electrically heated seats quickly take the chill out of even the coldest day. Three levels of warming automatically step down after several minutes to the lowest setting.
Separate left and right temperature controls allow the driver and passenger to enjoy personalized comfort. In addition to fully automatic or manual control of blower speed and airflow distribution, the system includes sun and humidity sensors, a dust/pollen filter, and an activated charcoal filter that automatically recirculates cabin air upon detecting a significant increase in smog. It also automatically adjusts to whether the retractable hardtop is open or closed.
Active multicontour seats offer adjustable lumbar supports, side bolsters and shoulder supports, for custom-tailored support. A massage feature helps prevent fatigue on longer drives, and offers settings ranging from gentle to more vigorous. Active side bolsters can be set to automatically increase lateral support in cornering maneuvers, or even in the event of a potential accident.
Active Ventilated seats are a luxury you'll soon consider a necessity. Three levels of heating and cooling ventilation are offered. By gently circulating air through perforations in the seat and backrest, Active Ventilated seats help keep you cooler and your clothes dryer during warmer months. On cold or damp days, using both the ventilation and heating features together can circulate the seat heating more quickly, to help keep you warm and dry.
At the touch of a button, a mesh screen rises from the rear cabin wall, helping to calm drafts and buffeting in the cabin for more comfortable and quiet top-down motoring. When not needed, it retracts elegantly into the rear cabin wall, out of sight and without taking up trunk space.
A leap in ease and efficiency pioneered by Mercedes-Benz, KEYLESS-GO® lets you unlock, start and drive away without removing the SmartKey from your pocket or purse. You can lock and unlock the doors with a touch of the exterior handles, and start the engine by stepping on the brake pedal and pushing the Start/Stop button on the dash. You can also start the vehicle in the conventional way by removing the Start/Stop button and inserting the SmartKey into the ignition.
As sensors on the inside mirror detect the headlights of vehicles behind you, both the inside and driver-side mirrors gradually darken to reduce reflected glare. To help maintain your rear vision, dimming is automatically cancelled when you shift to Reverse or if an interior light is switched on. The side mirrors are also automatically heated to help disperse mist and fog.
Program your Mercedes-Benz to illuminate its exterior lights when you unlock it in darkness, to help illuminate a path to your vehicle.
Three buttons on the rear view mirror can be programmed to operate many types of garage door openers, security gates and other HomeLink-compatible features. Disclaimer
Whether you're stuck in traffic or stopped on a hill, the HOLD feature lets you keep the brakes applied without your foot on the brake pedal. After bringing the vehicle to a stop, an additional press of the brake pedal activates the feature and illuminates a "HOLD" icon in the instrument cluster, letting you know you can relax your foot. The brake lamps stay illuminated while the car remains braked. When you're ready to move, just press the accelerator to release the feature and go. Disclaimer
You can raise the hardtop and open windows from outside the vehicle, simply by holding down the "lock" button on the SmartKey remote while aiming it at the infrared sensor in the driver's door handle You can also open the windows, and put the top down, by holding the "unlock" button in a simlar manner.
For convenient loading and unloading of the luggage when the hardtop is retracted, the Easy-pack system tilts the folded roof up when you press a button inside the trunk. With the optional HANDS-FREE ACCESS, it tilts up automatically when the trunk opens.
