P1044 FORMULA 1 GEARBOX
LEGACY PRODUCT
The P1044 gearbox is one of Xtrac’s legacy products, which whilst not currently in production, spares and technical support are still available upon request.
The P1044 gearbox was designed as a complete unit to be used by three teams all using Cosworth engines and derivatives have continued to be run since then.
In the context of F1, where every component is normally designed and manufactured as a bespoke item, Xtrac’s “batch-produced” gearbox with common parts offers significant cost savings, while technically remaining highly competitive. It also benefits from an extensive rig and engine dynamometer test programme.
With a contemporary longitudinal layout, commonly utilised in F1 gearboxes, the transmission can be easily adapted to other F1 engines. It positions the gear cluster forward of the differential to ensure excellent vehicle weight distribution, while meeting critical aerodynamic requirements at the rear of the vehicle.
