May 22, 2007 The clean fuel movement may have an unlikely ally in the task of bringing environmentally friendly motoring solutions to the market - Formula One racing. FIA president Max Mosley has announced a partnership with clean engine specialists Ricardo - and a plan that could see F1 cars running on clean biofuel and leading a "green revolution" by 2011. Under the plan, the current 2.4 litre V8 engines would be downsized to 2.2 litre turbocharged V6s running on biofuel. Maximum engine revs would be dropped from the current screaming 19,000rpm to 10,000rpm, making the cars far less noisy than they are currently. The estimated power output of the smaller engines would be around 770 horsepower, down about 100 compared to the present engines.
