BERLIN -- Mercedes-AMG unveiled the C 63, the new top model of the automaker's C-Class, with a hybrid drivetrain that replace the performance sedan's traditional V-8.
The hybrid powertrain produces 670 hp (680 PS, 500 kW) from a 469-hp, 2.0-liter, four-cylinder engine with a 201-hp electric motor on the rear axle. The combined maximum system torque is 1020 newton meters (752 pound-feet).
The electric turbocharger is integrated directly on the shaft of the turbocharger between the turbine wheel on the exhaust side and the compressor wheel on the fresh air side.
This electronically controlled motor drives the turbocharger shaft directly, accelerating the compressor wheel before the exhaust gas flow takes over the conventional drive.
The high-performance battery in the C 63 offers a capacity of 6.1 kWh, 70 kW continuous power and 150 kW peak power for ten seconds.
The 400-volt battery's lithium ion energy storage system was developed in cooperation between the High Performance Powertrains (HPP) Formula 1 engine shop in Brixworth, England, and Mercedes-AMG in Affalterbach, Germany.
