Nissan leads the auto industry in Continually Variable Transmissions, or CVTs, so for the launch of five new vehicles, a 70 percent design of the components was pretty important. For those who are unaware, a CVT virtually gets rid of fixed gears by using a metal belt that runs around two variable-diameter pulleys, traveling up the pulleys. This makes for incredibly smooth shifting. Nissan took it another huge step up by expanding to a 7.0 gear ratio range, reducing internal friction by 40 percent, and integrating better control logic.
