Sure, it may seem like any old Formula 1 steering wheel, but take a closer look. See that big red button sitting on the left side, just begging to be pressed? That, friends, would be a 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. We still don't really know what we'd do with all the other buttons, but we definitely know which one we'd keep our thumb on.
