A BMW M5 F10 goes head-to-head against the Porsche 911 Carrera 2S.

The Porsche 991 uses a direct injection 3.8-liter flat-six engine from the Carrera S model, with power increasing to 400 PS (294 kW; 395 hp). A Power Kit (option X51) is available for the Carrera S, increasing power to 430 hp, but the car raced here was stock.

New for the first time on a 911 model are electronic parking brakes (button selectable) and 20 inch diameter wheels. The car also features a new seven-speed manual gearbox, a first for a production car, along with an improved seven-speed Porsche Doppelkupplung (PDK) dual clutch transmission.

The F10 BMW M5 is powered by a high-revving 4.4-liter turbocharged unit that uses the BMW M TwinPower Turbo technology. The engine outputs 560 horsepower from 5,750-7,000 rpm and 680Nm (502 lb-ft) of torque from only 1500rpm. It comes in both manual and 7-speed DCT transmission.

Which one takes the win?
