The 2013 Mercedes-Benz SL 550 is a two-seat grand touring roadster from the R231 generation, factory-equipped to combine high-performance V8 propulsion with the convenience and refinement expected from a flagship convertible. It is powered by a 4.7-liter twin-turbocharged V8 mated to Mercedes-Benz’s 7-speed automatic transmission, delivering strong low-end torque and a smooth shift program optimized for both relaxed cruising and more energetic driving.
Powertrain and chassis
- 4.7-liter twin-turbo V8: A bi-turbo V8 providing the model’s standard power and torque characteristics, engineered for immediate response and broad torque delivery across the rev range.
- 7-speed automatic transmission (7G-Tronic): Electronically controlled automatic transmission with manual shift capability via steering-column paddle shifters; features adaptive shift logic to select gears according to throttle input and driving conditions.
- Rear-wheel drive layout with independent suspension front and rear: Designed to balance ride comfort and handling stability.
Exterior features
- Retractable hardtop roof: Three-piece power folding metal roof that stows in the trunk at the touch of a switch, converting the coupe into an open-top roadster while maintaining a sealed, insulated cabin when closed.
- Automatic lighting: Bi-xenon headlamps with adaptive/curve-illuminating functionality and integrated LED daytime running lights for improved visibility; LED tail lamps provide clearer signaling and longer life.
- Power exterior conveniences: Power-folding heated mirrors, rain-sensing windshield wipers, and a remote key fob for central locking and roof operation.
- Aerodynamic design elements and integrated trunk lid: Bodywork and roof mechanism engineered for low drag and a tidy stored-top profile.
Interior and comfort
- Leather seating and premium trim: Nappa leather upholstery on front seats and leather-wrapped steering wheel; interior trim options typically include wood or metal-look finishes as fitted from the factory.
- Heated and ventilated power front seats: Multi-way power adjustments with driver memory settings for seat and exterior mirrors; heating and ventilation functions are integrated for seasonal comfort.
- AIRSCARF neck-level heating (integrated into the headrests): A Mercedes-Benz feature that directs warm air around the neck area to extend comfortable open-top motoring in cooler conditions.
- Dual-zone automatic climate control: Maintains independent temperature zones for driver and passenger, with automatic recirculation and filtering modes.
- Convenience features: Keyless ignition (Keyless-Go), power windows, center console storage, and a multifunction steering wheel with audio and cruise controls.
Technology and infotainment
- COMAND system: Mercedes-Benz’s central control interface for audio, navigation and vehicle settings. Includes a color display screen and a central controller (rotary knob and buttons) for operation.
- Integrated navigation system: Factory navigation with map display and route guidance (where equipped as standard or part of a package).
- Bluetooth hands-free and audio streaming: Allows for voice-activated calling and wireless media playback.
- Media ports: Auxiliary and USB inputs for connecting portable audio devices; iPod integration capability.
- Premium audio system: A factory-fitted premium sound system calibrated for the SL cabin; higher-grade audio packages were available as options.
Safety and driver assistance
- Multiple airbags: Front, side-impact, and head airbags for front occupants, along with knee airbag protection for the driver.
- Antilock Braking System (ABS) and Electronic Stability Program (ESP): Standard electronic aids to help maintain vehicle control under braking and in low-traction situations.
- Brake Assist and traction control: Syste
