cvt transmission was invented by subaru back in 1970s but dropped the tech for a while. Honda, bmw and another car companies adopted and improved it today. It is a nice technology! I test drove a honda civic hx with cvt and it is very interesting. It is smooth and doesn't even change gears. It has infinite gear ratios, also. The tachometer needle was "stuck" at 5000 rpm while acclerating. It was cool!
