Toyota Debut's Prius GT Prototype at Goodwood Festival of Speed

The racing team in charge of the Prius GT's development has tinkered with the computer systems in charge of controlling the

electric and gasoline motors, specifically the switchover point between the two motors. With emphasis on performance, the transfer has been altered for speed rather than energy conservation. With these enhancements, the GT can scoot to 100 km/h in just 8.7 seconds, down from stock car's 10.5 seconds.

Aside from the typical red splashes and factory 'Works' vinyl-sticker livery, the Prius GT is fairly stock looking from the outside. The sleek, fastback body still features a top-of-class drag coefficient rating of 0.26 Cd, enhanced slightly with a front lip extension at the bottom of the front bumper as well as a small rear spoiler. Both are minor additions with the

As with any racing car, the suspension setup is critical. A change in setting can alter the way a car drives, benefiting or adversely affecting the outcome of a race. To help the car's pilot make the most of the Prius GT, the whole suspension system has been revised. Upgraded shock absorbers, springs and stabilizer bars increase the faster moving Prius GT's road-holding. These aren't off the shelf parts either, but professional grade components.
