Renault have new way of heating tires

An interesting idea that Renault now came up with is to actually use part of the hot air exhaust gases to heat up the rear tires. The R28 now features a modified rear wheel shield with an aerodynamic tunnel in it. This catches air from the inside of the shield and churns it out again just above the rear tire. Such device prevents the tire from being cooled by airflow, but allows a more constant temperate, hence improving its grip.
