Drivetrain
The BMW M6 uses a Petrol Turbo producing 412kW and 680Nm of torque, sent through a 7-speed m double clutch transmission with drivelogic to a RWD layout. It covers the 0-100km/h sprint in 4.2 seconds.
The Mercedes-Benz AMG GT responds with a Petrol making 430kW and 800Nm, paired to a 9-speed auto driving all four wheels. It gets to 100km/h in 3.2 seconds.
The Mercedes-Benz AMG GT has the clear power advantage at 430kW vs 412kW. In the 0-100 sprint (manufacturer-claimed), the Mercedes-Benz AMG GT is 1.0s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
