If this device is actually built like a mini torque converter from a snowmobile (I'm from northern Canada and have three snowmobiles, and the assemblies in them don't look the same.) then it will have very low efficiency, especially with an electric motor. Because the Troque converter in a snowmobile uses high RPMs to shift the belt ou farther and gain a higher ratio. The faster the motor spins the more torque you get. This is fine for a gas engine that is designed where the maximum torque output is very close to the redline RPM, but in an electric engine the max torque is a 0 RPM, so it would be impossible to get even close to your maximum torque out of a that sort of design with an electric engine.

Then again I have lots of snow machines, and spend most of my free time fixing snowmobiles, and that device doesn't look the same as whats under the hood of my Mach Z.
