The Continously Variable Transmission (CVT) used in the Flybrid system is a full toroidal system which is used under license from the developer Torotrak PLC of Leyland, UK.

The key CVT components are engineered and manufactured by Xtrac Ltd of Thatcham, UK who are a highly respected manufacturer of motorsport transmissions.

The three companies (Flybrid Systems, Torotrak and Xtrac) have worked together to develop a well engineered device and continue to work together to promote their joint interest in the project.
