Protean Electric In-Wheel Motors at Frankfurt Motor Show

The first BRABUS EV sedan, called the "High-performance Four-wheel-drive Full Electric Car," is based on the Mercedes-Benz E-Class. It features an all new EV system developed to demonstrate a peak combined 320 kW (430 hp) and 3,200 Nm (2,350 ft.-lbs.) torque from pure electric power using four direct-drive Protean Electric motors, one in each wheel.

A second BRABUS hybrid drive vehicle, called the "Technology Project Hybrid," also made its debut at the show. Powering the rear wheels in combination with the internal combustion engine, the Protean Electric in-wheel motors each add 80 kW (110 hp) and 800 Nm (590 ft.-lbs.) of peak torque. This gives the sedan a combined electric motor and internal combustion engine acceleration of 0-100 km/hr (0-62 mph) in 7.4 seconds and a combined electric motor and internal combustion engine acceleration of 60-120 km/hr (37-75 mph) of 5.6 seconds.

Beyond performance, the high efficiency and regenerative braking capability of the Protean Drive™ system in the hybrid car improve fuel economy about 30 percent vs. a comparable vehicle not equipped with the Protean Electric in-wheel motors.

In addition to Protean Electric, BRABUS also has worked with Boston Power, a leading maker of lithium-ion batteries. The EV and hybrid vehicles also represent the debut of Boston Power’s liquid-cooled module, Swing Medley™.

BRABUS is well known for its discerning use of only the best technology to perfect the performance of its elite supercars.

"BRABUS is proud of our collaboration with Protean Electric as an expression of our continued commitment to technological excellence," said Ulrich-Joachim Gauffres, executive vice president of Research and Development, BRABUS GmbH.

"We’re pleased to work with BRABUS to demonstrate what Protean’s EV and hybrid power can deliver to the world’s most discerning automotive customers," Protean CEO Bob Purcell said. "Our in-wheel motors not only provide for significant performance improvement, but do so in a very responsible manner – with better fuel economy and emissions as well."
