Thanks, my Bosch blue book doesn't have a lot of detail on how exactly a CVT works, only something about a band that moves between two cones.... I will find a book that explains it someday. But I agree, anytime someone claims an 'order of magnitude' efficiency improvement, it's time to be skeptical.
