A CVT. Finally. I had a gokart when I was a kid that had one of these, now I have a Nissan, and I've ridden snowmobiles with these. I've always thought this was the best way to transfer power. The drive ratio is always optimum for what you are trying to achieve: cruising, quick take off, saving fuel, whatever.
Just like my car the shifting is a little useless. It's just a calculated point at where the CVT should be. I never use it, but maybe it would be more use if I lived in the mountains where I needed to downshift.
I would love to give this a try.
