'Torque vectoring' key to race tire development

ERJ staff report (BC)

Geneva, Switzerland – Tire Business reports that Dunlop Motorsport's long heritage of competition at the 24 Hours of Le Mans race will take a new turn – literally and figuratively – this year with the development of race tires tuned to the specific "torque vectoring" characteristics of the GreenGT H2, a hydrogen fuel-cell-powered prototype racer.

Torque vectoring – defined as a car's ability to vary the amount of power sent to each wheel – will exert "significant" influence on tire design in coming years as "alternative fuel" race cars become more prevalent, according to Sebastien Montet, race design and development manager for Dunlop Motorsport, an operating unit within Goodyear Dunlop Tyres Europe.

"Torque vectoring cornering control is often seen as the 'Hand of God' for corner capabilities on the track and the road in the future," Mr. Montet said, "but the substantial benefits of this technology counts for nothing without the appropriate tire design.
