European auto component maker Gkn has developed a new eAxle module, which is currently used in supercars, for C-segment plug-in hybrid vehicles.
The module will enable the automakers to offer plug-in hybrid option in C-segment vehicles with enhanced performance and cuts CO2 emissions of the vehicles by over 50%.
GKN 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."
The new eAxle is an improved version of the system developed by Gkn for the Porsche 918 Spyder.
The single-speed design of the module reduces weight to just 20.9 kg, while optimizing efficiency, installation space and costs for mass-market vehicle applications.
The module comes with a two-staged geartrain with a gear ratio of 12.5 that offers 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.
The eAxle provides an additional 65kW of electrical power, which could take the engine output in a typical C-segment plug-in hybrid to about 100kW.
It can increase 0-100kph acceleration times by several seconds and offers a useable pure electric range.
Gkn Driveline managing director of eDrive Systems Rainer Link 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."
The components supplied by Gkn are being used in supercars like the Porsche 918 Hybrid and the BWW i8 sports car.
