Torvec's
Infinitely Variable Transmission
(IVT) combines the Company's innovative
and patented hydraulic pump technology with patented
gearing and valving resulting in a technological
breakthrough.
As of 2007, after extensive market research of CVTs, 6, 7 & 8-speed automatics we have not found any of these to be:
- Lighter in weight
- Less costly to MFG (fewer parts)
- Easier to control
- More compact
- Less complex
The IVT is completely scalable, from the smallest vehicle to the largest class - 8 truck.
