Engine and Performance: Under the Hood of the 2007 S550
Powertrain Specifications and Technical Foundations
The heart of the 2007 Mercedes-Benz S550 is its 5.5-liter V8 M279 engine, a culmination of Mercedes’ pursuit of balanced power and refinement. This engine generates a healthy 382 horsepower (at 6,000 rpm) and 391 lb-ft of torque (at 2,800 rpm). Such figures were notable at the time, offering rapid acceleration and highway stability. The engine’s design incorporates DOHC (Dual OverHead Camshaft) with four valves per cylinder, promoting efficient airflow and combustion efficiency.
Complemented by a seven-speed automatic transmission (7G-TRONIC), the drivetrain ensures smooth gear transitions, minimizing torque interruption while enhancing fuel economy relative to earlier V8 configurations. The vehicle’s all-wheel drive (4MATIC) system further enhances grip and handling, especially advantageous under adverse weather conditions.
Notably, the engine features variable valve timing and cylinder deactivation technology, which switch off some cylinders during light-load conditions to optimize fuel consumption—a feature that was an early indicator of industry trends towards efficiency within performance engines.
