Mercedes-Benz S550 PLUG-IN HYBRID

The new Mercedes-Benz S550 PLUG-IN HYBRID, based on the Mercedes-Benz parallel hybrid modular system, joins the new S-Class with 436 horsepower coming from an engine combination of a V6 biturbo and intelligent hybrid drive that goes from 0 to 62 mph in 5.2 seconds and drives electrically for up to 20 miles. The hybrid transmission is based on the 7-speed automatic transmission with an additional clutch integrated between combustion engine and electric motor. The S550 PLUG-IN HYBRID decouples the combustion engine during purely electric operation and, if the combustion engine is employed, it affords the possibility to move off drawing on the performance of a wet start-up clutch. The clutch then substitutes for the torque converter and requires no additional space owing to its complete integration in the torque converter housing. The high-voltage battery can be charged via external electricity mains using a 3.6 kW on-board charger.
