Additional Description: Transform your SL from closed coupe to open roadster in under 20 seconds, even as you accelerate up to 25 mph. With a single button on the console, the top folds into the trunk. An electric trunk partition moves into place automatically as you operate the top, while the rear window pivots 180 degrees to help preserve cargo space with the top stowed. The Panorama roof brings occupants 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. From its expressive headlamps to its boldly angular taillamps, long-lasting and energy-efficient LEDs accomplish every exterior lighting function with distinctive style. LEDs also offer quicker illumination, offering other drivers more time to react to your brake lamps and other signals.Generating 449 hp, the 4.7-liter V8 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. 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. With a greater range of ratios and shorter steps between gears, the 9-speed automatic changes gears more quickly but nearly imperceptibly. Along with more seamless delivery of power, the lighter, more versatile transmission enhances comfort and fuel-efficiency. A sleek electronic selector and sporty shift paddles let you change gears without taking a hand from the steering wheel. A multimode drive program selector on the console lets you transform the car's character with the push of a console button. Four modes (ECO, Comfort, Sport and Sport+) alter the throttle response, shift points, steering effort, ECO Start/Stop and more. A fifth "Individual" mode allows you to create a mode of your own, even letting you set the transmission for purely manual shifting. With the available Active Body Control (ABC) suspension, a CURVE mode enhances cornering comfort.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. Featuring a high-resolution color display and a central controller on the console, the Cockpit Management and Data (COMAND(R)) system gives you convenient control of audio, video, hands-free calling and navigation functions. Many features can also be accessed via the integrated steering-wheel controls. A leap forward in audio quality, FrontBass(R) takes advantage of the rigid bodyshell by utilizing the front frame members as resonance chambers for twin under-dash subwoofers. In addition to providing rich, precise bass throughout the interior, the design saves weight and frees up space in the cabin and doors. An expertly engineered harman/kardon LOGIC7(R) premium digital surround system fills the cabin with 600 watts of beautifully balanced audio. No fewer than nine strategically placed speakers plus two subwoofers deliver a wholly immersive listening experience through Dolby Digital 5.1 surround sound technology. Digital Dynamic Volume Control impeccably and imperceptibly maintains the sound spectrum for consistent listening pleasure in varying driving conditions.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. Radar-based technology can alert you if you're approaching a vehicle ahead, or even some stationary objects, at a speed and distance that suggest a collision is likely. As soon as the driver starts to brake, Active Brake Assist can automatically provide the ideal level of braking, to help prevent a collision or reduce its severity. The system can also provide autonomous braking at a range of driving speeds, and can activate the features of PRE-SAFE(R). If an air bag deploys, your car can automatically initiate a call to Mercedes-Benz Emergency Services, transmitting your GPS-determined location and helpful vehicle information on your behalf. Trained experts are on call 24/7 to help summon local emergency responders to your location. You can also press the SOS button in the vehicle anytime you need emergency assistance, or see someone else who does. This vital service is provided for as long as you own the vehicle, no matter who's driving. The first system of its kind, ATTENTION ASSIST(R) continuously monitors up to 70 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. With enhanced sensitivity, the system can also help detect drivers who begin their trip drowsy, and offer more useful information to drivers along their journey via a dashboard display.Let us show you all of the new features of the 2020 Mercedes-Benz SL 550 Roadster in person today at Walter's Mercedes-Benz of Riverside located at 3213 Adams St. Riverside, CA 92504.WOOD/LEATHER STEERING WHEEL,WHEEL LOCKING BOLTS,FLOORMATS,HIGH-GLOSS BLACK ASH WOOD TRIM,SOFT CLOSE DOORS,PANORAMA ROOF,GREY HEADLINER,WHEELS: 19" AMG MULTI-SPOKE ALLOY,DRIVER ASSISTANCE PACKAGE -inc: PRE-SAFE PLUS Active Distance Assist DISTRONIC Active Steering Assist Cross-Traffic Assist PRE-SAFE Brake BAS PLUS Active Brake Assist w/Cross-Traffic Function Active Blind Spot Assist Active Lane Keeping Assist Speed Limit Assist,ILLUMINATED DOOR SILLS,Turbocharged,Rear Wheel Drive,Active Suspension,Power Steering,ABS,4-Wheel Disc Brakes,Brake Assist,Brake Actuated Limited Slip Differential,Aluminum Wheels,Tires - Front Performance,Tires - Rear Performance,Tires - Front All-Season,Tires - Rear All-Season,Tires - Front All-Season,Tires - Rear All-Season,Sun/Moonroof,Generic Sun/Moonroof,Panoramic Roof,Heated Mirrors,Power Mirror(s),Integrated Turn Signal Mirrors,Power Folding Mirrors,Rear Defrost,Intermittent Wipers,Variable Speed Intermittent Wipers,Rain Sensing Wipers,Convertible Hardtop,Rollover Protection Bars,Power Door Locks,Daytime Running Lights,Automatic Headlights,Headlights-Auto-Leveling,AM/FM Stereo,Satellite Radio,Bluetooth Connection,HD Radio,Requires Subscription,CD Changer,CD Player,MP3 Player,Steering Wheel Audio Controls,Auxiliary Audio Input,Hard Disk Drive Media Storage,Smart Device Integration,Smart Device Integration,Smart Device Integration,Satellite Radio,HD Radio,Requires Subscription,Premium Sound System,Power Driver Seat,Power Passenger Seat,Seat Memory,Heated Front Seat(s),Cooled Front Seat(s),Adjustable Steering Wheel,Trip Computer,Power Windows,Telematics,Requires Subscription,Leather Steering Wheel,Keyless Entry,Power Door Locks,Keyless Start,Keyless Entry,Power Door Locks,Hands-Free Liftgate,Universal Garage Door Opener,Cruise Control,Climate Control,Multi-Zone A/C,A/C,Leather Seats,Auto-Dimming Rearview Mirror,Driver Vanity Mirror,Passenger Vanity Mirror,Driver Illuminated Vanity Mirror,Passenger Illuminated Visor Mirror,Floor Mats,Mirror Memory,Keyless Start,Remote Engine Start,Navigation System,Power Windows,Power Door Locks,Trip Computer,Bucket Seats,Seat-Massage,Mirror Memory,Security System,Engine Immobilizer,Traction Control,Stability Control,Traction Control,Front Side Air Bag,Telematics,Requires Subscription,Automatic Parking,Tire Pressure Monitor,Driver Air Bag,Passenger Air Bag,Front Head Air Bag,Passenger Air Bag Sensor,Knee Air Bag,Back-Up Camera
