Mercedes-AMG to Deploy Motor technology Possibly Eliminating rear Brakes
Stuttgart,Germany – December 7,2023 – Mercedes-AMG is poised to revolutionize electric vehicle design with the integration of axial-flux motor technology developed by Yasa,a UK-based company acquired by the automaker in 2022. This innovation allows for a highly integrated powertrain potentially capable of eliminating the need for conventional rear brakes through regenerative braking,substantially reducing vehicle weight and increasing efficiency.
The breakthrough stems from the compact and powerful design of Yasa’s axial motors. Unlike customary radial motors, these axial designs are flatter, enabling substantial space savings within the vehicle chassis.This freed-up space, coupled with the motors’ inherent ability to recapture energy during deceleration, opens the door to a future where rear friction brakes are rendered obsolete. Manufacturers gain “unprecedented freedom to redesign and optimize the packaging, aerodynamics and kinematics” of their vehicles, according to industry analysis. The technology promises lighter, more efficient cars and a substantial redesign of vehicle architecture.
While the initial application of Yasa’s motors in the upcoming all-electric Mercedes-AMG GT 4-Door sedan and SUV will utilize a conventional one front, two rear motor configuration, Mercedes-AMG is reserving the full potential of the in-wheel motor design for future models. This phased approach allows for refinement and validation of the technology before deploying the moast radical aspects of the system.
Yasa’s axial-flux motor technology delivers higher power density and torque than conventional motors, contributing to improved vehicle performance and range. The technology has already garnered a user assessment of 4.3 out of 5 stars from 15 voters, signaling strong early confidence in its potential. The move underscores Mercedes-Benz’s commitment to electric mobility and its ambition to lead the industry in powertrain innovation.
