Rolls Royce 102EX Uses UQM PowerPhase Propulsion Systems

After Saab and Audi, who have both chosen the UQM Technologies electric propulsion systems to power their pre-production test fleets, it is now Rolls-Royce’s turn to do the same. Specifically, the 102EX vehicle, introduced by the automaker in early Mach at the Geneva auto show, will use an electric drive system provided by UQM Technologies.

“The selection of our PowerPhase systems by Rolls-Royce reinforces our ability to build and provide electric-propulsion solutions for a wide variety of vehicle platforms,” added Ridenour. “Our systems are used in a variety of vehicles from a motorcycle up to a transit bus, and now in an ultra-luxury car.”

The 102EX uses two 145kW PowerPhase electric propulsion systems to deliver the performance required by Rolls-Royce. Combined, the electric motors produce 388 horsepower and 590 ft-lbs (800 Nm) of torque.

“Our electric motors deliver high-power output in a small package, requiring minimal space in the vehicle – a crucial requirement in the Rolls-Royce project,” said Eric Ridenour, President and CEO of UQM Technologies. “Additionally, the quality, performance and craftsmanship of our PowerPhase electric propulsion system make it a great match for the ultra-luxury Rolls-Royce brand.”

According to the British automaker, the 102EX will undertake a global test programme that takes in Europe, the Middle East, Asia and North America. Through test drives, owners will be given the opportunity to experience an alternative drive-train technology and to feed back their experiences, thoughts and concerns directly to Rolls-Royce.

Other new systems incorporated into the newly developed 102EX include a new battery system from Axeon and HaloIPT wireless charging technology, as well as an Xtrac prototype transmission.
