PorscheThat big red button sitting on the left side, is the boost button, capable of giving this Porsche 911 GT3 R Hybrid racer an extra burst of acceleration.

Unlike most battery powered hybrids, both the 911 GT3 R and the 918 RSR run on an inertial flywheel that’s spun by the momentum generated whenever the car brakes.

All it takes is one tap of the boost button, however, for that momentum to be instantly converted into a potent jolt of KITT-like horsepower.

It’s not enough for the car to feature a flywheel system so awesome. The Germans had to give the car the world’s most awesome videogame controller.
