Active Wheel Explained

Active Wheel was a Michelin-developed tire which incorporates an electric motor and suspension^[1] It was presented at Challenge Bibendum 2004's edition on the Hy-Light concept car and showcased during Paris Motor Show "Mondial de l'automobile"in 2008 both on the Venturi Volage electric sports car and on the Heuliez Will.^[2] The project was interrupted in 2014.^[3]

Like other in-wheel motors, the ActiveWheel design provides direct power delivery of approximately 30kW, as well as regenerative braking. In addition, it replaces a mechanical suspension with an active suspension driven by an in-wheel electrical suspension motor that controls torque distribution, traction, turning maneuvers, pitch, roll and suspension damping for that wheel.^[4] However, the effects of shocks, water and snow to such an "in-wheel" design have not been precisely studied.

Siemens VDO, developing a similar concept called eCorner,^[5] ^[6] was purchased by Continental in 2007.
