GKN’s all-new coaxial electric axle system, the eTwinsterX, is now in the prototype stage, with a working example up-and-running in a demonstrator vehicle, which is being put through its paces as part of GKN Driveline’s Wintertest engineering event.
The eTwinsterX system features an integrated e-motor, two-speed e-transmission, and torque vectoring capability using GKN’s unique Twinster clutch pack technology. It employs a 120kW downsized e-motor, delivers maximum torque of 3,500Nm, vectors up to 2,000Nm to each rear wheel, and can operate up to maximum vehicle speeds of around 250kmh.
Peter Moelgg, CEO of GKN Driveline’s AWD and eDrive business, said, “When we revealed this concept at Frankfurt last year, we said that eTwinsterX would deliver unrivaled capabilities for the next generation of electric vehicles. Our team has worked hard to prepare the first prototype for the Wintertest program, and we look forward to demonstrating the system in full.
“The dynamic development of eTwinsterX is testament to GKN’s unique position in being able to deliver an integrated e-motor, two-speed e-transmission and torque vectoring within a complete eAxle system. Our calibration expertise also means that we can optimize these technologies to deliver fully brand-aligned experiences for our global OEM customers.”
