GKN brings supercar hybrid technology to mass market
Porsche 918 Spyder
GKN Driveline announced that developed an eAxle module for C-segment plug-in hybrids, using its experience with previous eAxle for Porsche 918 Spyder, BMW i8 and Volvo XC90 T8 Twin Engine.
The new eAxle is being prepared for the mass market so between the lines we read that there must be a new plug-in hybrid in the works.
GKN Driveline said that we could expect 65 kW of power from the electric part (on top of around 100 kW from the engine).
GKN Driveline eAxle module:
"The new eAxle is an evolution of the system GKN designed for the Porsche 918 Spyder. The single-speed design minimises weight to just 20.9kg while optimising efficiency, installation space and costs for mass-market vehicle applications. A two-staged geartrain with a gear ratio of 12.5 provides up to 2000Nm torque and 65kW power for a dynamic pure-electric mode and balanced wheel torques for all-wheel drive mode. An electromechanically actuated dog clutch disconnects the electric motor at higher vehicle speeds and an open coupling minimises rotating losses when disengaged. Precision engineering of the gear teeth and other acoustic measures ensure noise emissions are minimal.

Development by GKN is helping move the balance of power in vehicles from internal combustion towards electric drives. A typical C-segment plug-in hybrid could now have an engine output of around 100kW, with a GKN eAxle supplying an additional 65kW of electrical power. The eAxle can improve 0-100kph acceleration times by several seconds, provide a useable pure electric range and reduce a vehicle's CO2 emission rating to less than 50g/km.
Front-wheel drive vehicle platforms can integrate GKN's compact, lightweight single-speed eAxle modules into the vehicle's rear assembly to provide a combination of plug-in hybrid and electric all-wheel drive functionalities."
GKN Automotive President of Engineering Peter Moelgg said:
"GKN leads the industry in eAxle technology and we want to make plug-in hybrids a simple upgrade for consumers and manufacturers. With our systems now proven in halo hybrid sports car programmes and premium SUVs, automakers are working with us to launch eAxle technology in a much broader range of vehicles. Innovations by our hardware and software engineers will place the performance and efficiency benefits of plug-ins within the reach of many more motorists."
Rainer Link, GKN Driveline Managing Director of eDrive Systems, said:
"GKN's position as the only hybrid technology supplier that can also deliver complete all-wheel drive systems makes us an ideal partner on these programmes. Our vehicle integration teams can support automakers in the tuning of their vehicle's eAWD mode, ensuring that the torque delivery results in the right front-rear balance and delivers the brand's trademark driving characteristics."
