More Torotrak News

Another press announcement from Torotrak, this time slightly more relevant to the real world. A bus fitted with a prototype Torotrak IVT transmission demonstrated a 19% improvement in fuel economy compared with the standard 5-speed automatic transmission.

The bus, an Optare Solo 60-seat vehicle, was fitted with a Torotrak IVT transmission and run through the Millbrook London Transport Bus cycle at the Millbrook test facility in Bedfordshire. It is an intensive stop-start cycle, which sounds like it should make the highest demands on any vehicle on the test.

Torotrak seem to think that with a purpose built transmission the gains could be even higher. Optare are, apparently, interested in putting the IVT into production. I would imagine that if the transmission can be incorporated at minimal additional cost the bus operators would be keen on the potential reduction in operating costs.
