Toroidal CVT based on Nissan's Extroid

This is a model of a toroidal continuously variable transmission. Continuously variable transmissions (CVTs) are now used in many economy cars, but they use a belt and are designed for efficiency. Nissan's Extroid transmission stood out to me because it is one of the few CVTs designed with performance in mind. It was made to handle up to 350 horsepower and power the rear wheels in a front engine car. Instead of using a belt, it uses toroidal shaped geometry to vary drive ratio, something unique to the Extroid.
