Year Introduced: 2009
Sport: F1 Racing

Ever get sick of stop-and-go city traffic? If only you had KERS. An automotive system that recovers wasted kinetic energy, KERS works by collecting all of the heat you build up from hitting the brakes and then storing that power to boost acceleration later on. Basically, it's like saving a Mushroom for the finish line when you're playing Mario Kart. Due to the system's weight, though, most F1 racers have been slow to include the innovation in their cars.
