Torotrak developments
As conventional torque converter-based automatic transmission design and engineering advance steadily due to the use of software control and the advent of six-speed systems, the challenge for companies trying to interest OEMs in something very different becomes difficult.

Torotrak, which has been involved in the design and development of an infinitely variable transmission (IVT) for 15 years, knows just how difficult it is to break new ground on OEM thinking in this area, but it has recently been demonstrating its latest Series-3 system to potential users or manufacturers in the U.S., Europe, and Far East.
