Torotrak supplies prototype IVT for Tata Motors concept car

Technology developer Torotrak has supplied a prototype transmission to India-based Tata Motors for use in the Tata Pixel concept car, revealed at the 2011 Geneva Motor Show.

The four-seat urban vehicle uses a Torotrak infinitely variable transmission (IVT) to provide responsive performance, good fuel economy and manoeuvrability.

When parking and during tight manoeuvring, the transmission’s ability to control each rear wheel independently is used to enable rotation of these wheels in opposing directions.

By linking the vehicle’s steering system with the control mechanism for the IVT, the car is able to pivot around its rear axle, boosting manoeuvrability and enabling parking in tight spaces.
