GKN Driveline’s eAxle enables plug-in powertrains for mass-market vehicles

GKN Driveline eAxle

GKN Driveline has developed an eAxle module designed to enable C-segment vehicles to offer buyers a plug-in hybrid option with both improved performance and reduced emissions.

The new eAxle is an evolution of the system GKN designed for the Porsche 918 Spyder. The single-speed design minimizes weight to just 20.9 kg (46 lbs) while optimizing efficiency, installation space and costs for mass-market vehicle applications.

A two-stage geartrain with a gear ratio of 12.5 provides up to 65 kW of power and 2,000 N·m of torque. An electromechanically actuated dog clutch disconnects the electric motor at higher vehicle speeds and an open coupling minimizes rotating losses when disengaged.

Using GKN’s technology, a typical C-segment plug-in hybrid could have an engine output of around 100 kW, with the eAxle supplying an additional 65 kW of electrical power. The eAxle can improve 0-60 acceleration times by several seconds, provide a useable pure electric range and reduce a vehicle’s CO2 emissions to less than 50 g/km, the company said.

“We want to make plug-in hybrids a simple upgrade for consumers and manufacturers,” said GKN’s President of Engineering Peter Moelgg. “With our systems now proven in halo hybrid sports cars and premium SUVs, automakers are working with us to launch eAxle technology in a much broader range of vehicles.”
