“The motors reside in the space behind the wheel, producing torque and power exactly where and when drivers need it,” the company says. The new production motor is said to provide a 25% increase in peak torque compared with Protean’s previous design. It can deliver 735 foot-pounds of torque and 100 horsepower.

“It is also powerful enough to be the only source of traction drive in electric vehicles,” the company says.

‘Ready to Enable’

“Protean Electric is ready to enable the global automobile industry as it moves to high volume, low cost hybrid and electric drive powertrains,” Protean chairman and CEO Bob Purcell says in a release. “Our system can be applied to current vehicle platforms, retrofit existing vehicles or create all new architectures for the future.”

Protean claims fuel economy improvements of up to 30% in hybrid configurations, as compared to the base vehicle, depending on battery size, as well as superior regenerative braking, allowing as much as 85% of available kinetic energy to be recovered.

Each Protean motors weighs just 68 pounds.

Protean has demonstrated its wheel motors on vehicles including a Vauxhall Vivaro cargo van, a Guangzhou Automobile Industry Group (GAC) Trumpchi sedan, a Ford F150 pickup, and Brabus full electric and hybrid vehicles, based on the Mercedes-Benz E-Class.
