The P1289 is a descendant of the innovative P1227 transmission and features a single speed 3-shaft configuration with an integrated park-brake and a high performance motorsport limited slip differential.

Aston Martin selected this transmission for their first all-electric car – the Rapide E – which required a lightweight, extremely efficient and package optimised solution. As a result of working closely with the vehicle design team and Integral Powertrain, the motor supplier, this highly integrated transmission utilises two rear mounted electric motors producing a combined target output of just over 610PS (450kW) and a colossal 950Nm of torque, providing the balance of power and refinement required for such a vehicle.
