The instantly legendary AMG biturbo V8 heart beats even stronger in the SL 63. Output reaches a breathtaking 577 hp, 590 lb-ft of torque, and a 196-mph top track speed. Twin-scroll turbos with low-friction bearings are located in the engine's "hot V" for virtually-lag-free boost. SL-specific enhancements include active crankcase ventilation, repositioned intercoolers and higher boost. Yet even with its advanced technologies, each AMG engine is still hand-built and signed by its own craftsman.
The 9-speed multiclutch transmission's AMG SPEEDSHIFT® MCT technology shortens shift times and offers quick multi-gear downshifts. A wet startup clutch eliminates the torque converter, improving performance and, along with a magnesium casing, saving weight. The AMG DYNAMIC SELECT Sport, Sport+ and RACE programs, as well as a selectable Manual mode, progressively quicken upshifts and rev-match downshifts, while Comfort mode can decouple the driveline to save fuel when coasting.
The first SL with all-wheel drive, its 4MATIC® system can instantly vary the front-to-rear torque split in precise response to driving conditions and driver inputs, including 100% rear-wheel drive. An electromechanical coupling between the front and rear axles is controlled based on an elaborate matrix of driving mode, lateral and longitudinal acceleration, and available grip to optimize handling and acceleration right up to the physical limits, on virtually any road or track surface.
AMG DYNAMICS expands the functions of the 3-stage ESP® with the AMG Performance 4MATIC+ all-wheel drive for enhanced agility in a variety of driving modes and situations. In addition to "Basic" damping and stability settings in the Slippery and Comfort modes of AMG DYNAMIC SELECT, Sport mode selects "Advanced" settings for yaw, damping and steering response. In Sport+, "Pro" further sharpens agility and feedback, while models with the RACE mode can specially activate track-focused "Master" settings.
In keeping with the SL's sportier direction, a finely tailored 3-layer acoustic soft top is nearly 50 lbs lighter than the previous model's retractable hardtop. At driving speeds up to 37 mph, the top powers up or down in via its own switch panel or the central touchscreen, which animates the 15-second process. The clever Z-fold design lets the lowered top form its own flush rear deck, further saving the weight, complexity and visible seams of a conventional cover.
Pioneered by Mercedes-Benz, active LED headlamps can generate light that's perceived much like natural daylight. Active Curve Illumination and Adaptive Highbeam Assist adjust the LEDs in each headlamp to help maximize the illumination of corners and straightaways, without creating glare for other drivers.
Virtually every body detail benefits from extensive wind-tunnel refinement. The AIRPANEL system includes active louvers in the lower grille that can close to help cut drag and reduce front-axle lift. Or they can open to channel cooling air to the running gear based on the temperature of key components.
A network of LEDs can create not just a soothing ambience in the cabin, but one you can alter to suit your mood, or even create one. The 64 selectable colors and adjustable brightness let you control the atmosphere like never before. Edge-lighting glows from numerous cabin areas, while the front door sills welcome you with AMG logos backlit in soft white.
Brushed metal pedals with rubber studs offer confident footwork with high-performance style.
A breakthrough in automobile cockpit control, the Mercedes-Benz User Experience is further enhanced in the SL. MBUX integrates digital in-dash displays including a touchscreen, touch-sensitive controls, Bluetooth® hands-free and audio streaming, and an industry-advancing voice control system that responds to your everyday speaking voice and phrasing of commands. You can set up multiple user profiles of favored settings, and groups of settings can be saved as themes or moods.
Innovative Touch Controls elevate the multifunction steering wheel to an unparalleled level of user-friendliness. Finger-sensitive buttons access features like audio, Bluetooth® and cruise control. Four smartphone-like pads offer direct control of countless cockpit features. The upper touchpads operate the menu screen in the gauge cluster or the central multimedia display. Larger, lower touchpads let you vary your cruising speed or adjust the audio volume, all with your hands on the wheel.
One of the most respected makers of handcrafted high-end home audio, Germany's Burmester® has developed a surround-sound system that's specifically tailored to the SL. With 10 high-quality speakers plus a subwoofer and a 650-watt, 12-channel digital amplifier, the system can fill the cabin with pure surround sound while seamlessly compensating for ambient noise. Exquisitely detailed aluminum speaker grilles are as rewarding to the eyes as the system's output is to the most discerning ears.
Near-Field Communication (NFC) technology allows wireless charging of a compatible phone or other device that supports the Qi standard. An inductive charging tray in the console lets you charge your device's battery while you drive without plugging it in.
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.
The first system of its kind, ATTENTION ASSIST® 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.
Interpreting information that is continually supplied by the car's Electronic Stability Program (ESP®), electric power steering and suspension sensors, Crosswind Assist can help detect the effects of strong side winds on the vehicle's handling stability at highway speeds. Whether caused by lateral gusts or even a passing truck, the system can help keep the car on course via strategic braking of the wheels on one side of the vehicle.
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 you start to brake, it can automatically provide an appropriate level of braking to help prevent a collision or reduce its severity. If you fail to respond, it can also initiate braking automatically at a range of driving speeds. The system can also detect and react to crossing pedestrians at typical city speeds.
When traveling above approximately 20 mph, radar technology can help sense when a vehicle enters the blind-spot area. Blind Spot Assist can then alert the driver via an illuminated red icon in the appropriate side mirror. An audible warning sounds if the driver activates a turn signal while a vehicle is detected in the blind spot. After parking, Exit Warning Assist can alert the driver or passenger to vehicles, cyclists or pedestrians that could be at risk if the door is opened.
