Drivetrain
The Mercedes-Benz C-Class uses a Petrol producing 150kW and 300Nm of torque, sent through a automatic to a RWD layout. It covers the 0-100km/h sprint in 7.3 seconds.

The Mercedes-Benz C-Class has the clear power advantage at 150kW vs 127kW. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
