Rotrak is combining two unique technologies to provide a compact variable drive supercharger. This will enable cost-effective engine downsizing and CO2 reduction.

Variable drive superchargers for more efficient, downsized engines

NEW - Rotrak "How it works" Animation

Established in May 2010, Rotrak is 50:50 joint-venture between traction drive specialist Torotrak plc and centrifugal supercharger company Rotrex A/S. The company combines Torotrak's compact variable drive technology with a compressor technology developed by Rotrex that has been proven in motorsport and the performance vehicle market.

By combining these technologies Rotrak is addressing the automotive industry's need for affordable, effective engine downsizing. Improving engine efficiency will reduce CO2 emissions for legislators and fuel consumption for customers.

Rotrak is introducing a cost-competitive, compact variable drive that gives engine designers complete control over the compressor speed. The technology can overcome many of the technical challenges associated with current turbocharging and supercharging systems. It can also enable more radical engine downsizing and provide a more enjoyable driving experience.

Rotrak's technology solution has the ability to outperform the most sophisticated current systems when fitted to small engines. The key selling points of the concept are cost-competitiveness against complex turbocharger systems and its outright performance.
