Evolving the hybrid powertrain surely seems to be a massive exercise in the right direction. GKN, who have been supplying advanced electric motor transmissions to Volvo, among others, have begun testing the eTwinsterX all-in-one eDrive system. For this, they have adopted a Mercedes-AMG GLA 45, re-engineering it to be a plug-in hybrid with a pure electric drive mode.
The eTwinsterX, a co-axial electric axle system, features an integrated e-motor, a two-speed e-transmission, and torque vectoring capability using GKN’s unique “Twinster” clutch pack technology. It employs a 120-kW (163-PS) downsized e-motor, delivers a maximum torque of 3,500 Nm, vectors up to 2,000 Nm to each rear wheel, and can operate up to maximum vehicle speeds of around 250 km/h.
The eTwinsterX system also has capabilities beyond any present electrified driveline. It is significantly smaller than systems with equivalent power outputs, enabling easy integration into a multitude of vehicle platforms, and in a variety of layouts — front-, rear-, or all-wheel drive — leading to a range of potential applications.
