Porsche has gone big on power with the new Cayenne Turbo Electric, with 1,140 horsepower to play with in boost mode. This newly developed drivetrain utilises two e-motors positioned on each axle and delivers 845 hp to all four wheels. In order to unlock the full amount of power on offer, the Cayenne features a steering wheel mounted push-to-pass button that will give the driver ten seconds of peak power. Capable of going from 0 to 62mph in 2.5 seconds and 124 mph in 7.4 seconds, the Cayenne Turbo Electric maxes out at 162 mph as its top speed.
