2013 Mercedes Benz S550

The 2013 Mercedes-Benz S550 is the final and most technologically polished model year of the fifth-generation W221 flagship chassis. Representing the pinnacle of full-size German luxury sedans from its era, the S550 balances ultra-quiet cabin isolation, high-speed highway cruising stability, and twin-turbocharged V8 performance. Under the long bonnet, the 2013 model utilizes the 4.7-liter M278 Biturbo V8 engine, outputting 429 horsepower and 516 lb-ft of torque available from just 1,800 rpm. Engine power flows through a 7G-TRONIC 7-speed automatic transmission to either a Rear-Wheel Drive (RWD) setup or Mercedes' 4MATIC Permanent All-Wheel Drive system. An adaptive AIRMATIC air suspension setup absorbs road imperfections, maintaining a flat ride height regardless of load. The interior features premium hand-stitched leather upholstery, hand-polished Burl Walnut or Black Ash wood veneers, 14-way power-adjustable active multicontour seats with heating and ventilation, dual-zone automatic climate control, soft-close doors, and a 15-speaker Harman Kardon LOGIC7 surround sound system. High-end safety technologies—such as DISTRONIC PLUS adaptive cruise control, Night View Assist PLUS with pedestrian detection, Active Blind Spot Assist, and Active Lane Keeping Assist—make the W221 chassis a technological benchmark for its generation.
