CVTs aren’t a new idea. Snowmobiles have used similar drive-trains for years; and why not? They’re generally more efficient and they don’t have fixed shift points like traditional gearboxes. Yet, with the exception of Nissan and maybe Audi, automakers have been reluctant to embrace the CVT.

But that may soon change. A company called Fallbrook Technologies has developed an all-new type of CVT they call a continuously variable planetary transmission.

Named after Leonardo da Vinci, the NuVinci CVP as they call it can be used in countless applications ranging from bicycles to power-generating wind turbines.
