The Michelin Active Wheel challenges a lot of conventional wisdom about the car, according to its maker, who says: «with the integration of the Michelin Active Wheel, an EV can be redesigned from top to bottom since all key components—the engine, electrical suspension systems, tyre and brakes—are now integrated in the wheel.
In this way, the Michelin Active Wheel opens new possibilities for creative solutions in at least five different areas:
- Design.
- Energy savings and pollution abatement.
- Safety.
- Comfort.
- Adapting vehicles to usage needs.
Simplifying vehicles creates new opportunities in vehicle design by freeing styling teams from constraints previously thought to be inevitable. These include the elimination of the engine block, a considerable reduction in weight, the possibility of a totally flat floor on future prototypes, and chassis design that is fully focused on interior space and passenger safety.
A lighter vehicle also means a sharp reduction in energy consumption.
In fact, an EV emits no pollutants when on the road. Its environmental impact depends solely on how the electricity is produced. For example, using the WILL in a country where electricity is produced by hydroelectric power plants or renewable energy sources will result in very low indirect emissions of CO2 per km. This would represent less than 10g in Sweden, 20g in France and 80g in Germany.
This reinvented wheel also makes unprecedented improvements in active safety, meaning the avoidance of accident risks. The integrated electrical suspension system with four independent wheels is perfectly adapted to controlling pitching and rolling motions. This new electrical chassis control enhances vehicle stability and road holding. As for passive safety (i.e. protecting passengers in the event of an accident), the front of the vehicle where the engine was previously located is now entirely dedicated to impact absorption.
The permanent control of chassis movements and noise-free electrical engine combine to provide unparalleled comfort.»
