Drivetrain
The Porsche 911 uses a Petrol producing 290kW and 450Nm of torque, sent through a 8-speed pdk to a RWD layout. It covers the 0-100km/h sprint in 4.1 seconds.
The Audi R8 responds with a 4.2-litre V8 petrol direct injection (FSI) making 309kW and 430Nm, paired to a 6-speed manual driving all four wheels. It gets to 100km/h in 4.6 seconds.
The Audi R8 has the clear power advantage at 309kW vs 290kW. In the 0-100 sprint (manufacturer-claimed), the Porsche 911 is 0.5s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
