Ricardo launches new "˜E-Axle' electric vehicle transmission

Prompted by the rising demand for battery electric vehicles (EVs) and the increasing range of electric machines available for selection by automakers, Ricardo has created a single-speed EV transmission, the first in a planned range of such products, using knowledge and experience developed both on and off the track. Capable of accommodating both high torque and high input speeds, this advanced modular EV transmission will be revealed at the LCV event today. The E-Axle can be used in a wide range of installed orientations, and is equipped with high strength, lightweight aluminium casings that are ideal for direct integration into space-constrained environments.

"It's imperative that to support the driveline requirements of tomorrow's electric vehicles, we utilize our experience gained across a number of demanding projects and sectors to develop a product that can be manufactured in niche volume and short lead times," commented Ricardo Performance Products MD Mark Barge. "With our new E-Axle EV transmission, we are offering a highly adaptable solution that will provide an extremely cost-effective means of delivering high-quality electric traction to the road. We look forward to supporting customers "“ from the established automotive industry to EV start-ups "“ with this flexible transmission product."
