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.
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 SL400'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.
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.
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.
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.
All new Mercedes-Benz vehicles are protected by our New Vehicle Limited Warranty, covering defects in material or workmanship for 48-months or 50,000 miles, whichever comes first. For added protection, the Mercedes-Benz Extended Limited Warranty offers continued peace of mind with prolonged coverage tailored to your needs.
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.
