Parasitic power loss has been the bane of automotive engineers for decades. Be it from drivetrain components or tires, only a fraction of the energy created by our favorite four-stroke sequence actually finds its way to the pavement. Michelin recognizes that tires play a particularly crucial role, especially when its research shows that 20-percent of energy is lost through the rubber gumballs. So the French tire firm has set a goal to lower rolling resistance by 50-percent, while simultaneously doubling tread wear and reducing braking distances.
