The Torvec IVT is a version of a hydrostatic system.
The half toroidal IVT is requires a more complex and costly control system than the full toroidal IVT.
Most of the CVTs currently in the market for passenger cars are belt or chain CVTs which have torque limitations and offer less fuel economy than the Torotrak full toroidal IVT.
Alternative technologies that can reduce fuel economy, most of which are more costly than the IVT and offer a smaller fuel economy improvement.
Our success depends on our continuing ability to establish, protect and enforce our proprietary rights relating to the IVT.
