Technology Director Greenwood retires

Torotrak’s Technology Director, Chris Greenwood, retired on September 30th after 32 years in the transmission business. A founding father of Torotrak’s full-toroidal traction drive technology, Chris was involved at the very start of its development when, in 1978 and whilst employed by Leyland Vehicles, he undertook research and development into traction drives for application to trucks and buses. He was instrumental in setting up the CVT (continuously variable transmission) group that eventually evolved into the Torotrak business.

Chris was responsible for leading the development of Torotrak’s technology and the management of the Company’s patent portfolio and, as Torotrak’s leading inventor, has his name on over 50% of the patents and patent applications owned by the business.

Presenting a clock in the shape of one Torotrak’s toroidal discs to Chris upon his retirement, CEO Dick Elsy thanked him for his outstanding contribution and for the rich technical legacy that Chris leaves behind him.  Chris said that the past 32 years had passed quickly due to his love of “finding out how things work and solving problems.” Chris was also given a satellite navigation system as a gift from colleagues.

Although his longer term retirement plans include a move to France, Chris plans to stay close to Torotrak and to be able to advise the company on technology matters in the future.
