The P1080 gearbox is a high performance in line touring car gearbox that has been designed specifically for the World Touring Car Championship and is suitable for the British Touring Car Championship.

The P1080 makes use of Rally derived gear ratios with minimised size and weight to reduce inertia. The gearchange system incorporates the latest polynomial barrel track design and low inertia gearchange rack to improve gearchange response and driver feel.

The gears have been re-ordered to allow the overlap of barrel track profiles.
