If Max Mosley, president of the FIA, gets his way, Formula One will switch to V6 engines in 2011.

The 2.2 litre turbo-charged formula, with powerplants limited to just 10,000 rpm and running on biofuel, was set out by the FIA president in a letter to manufacturers, according to the magazine F1 Racing.

The radical proposal, to make F1 technology more cost-efficient, road relevant and environmentally friendly, will also involve single engines being used for a minimum of five grands prix, compared with the current two.

Also proposed for the 2011-2014 regulations are four-wheel drive, power-boost buttons and "severely constrained" aerodynamics, such as the limitation of wind tunnel use, and the document was also sent to Volkswagen and Ford, who may enter F1 in the future.

"We understand that such an approach has broad support from the competing manufacturers," Mosley said. (GMM)
