F1 cars might switch to turbocharged 2.2 litre V6 engines in 2011, if FIA president Max Mosley gets his way. And these engines might just use biofuel, and drivetrains might use all-wheel drive. Also suggested are power boost buttons much like the A1GP style, which should be achievable by upping the turbocharger boost.
These changes are an effort to make the F1 sport more cost-efficient, road relevant and environmentally friendly. Part of the environmentally-friendly strategy is to use a single engine for at least 5 GP races, instead of the current 1 engine to 2 race ratio.
Currently F1 cars are 2.4 litre V8s, having dropped from 3.0 litre V10s in 2006. The last use of a turbocharger in F1 was in 1988, with a ban being imposed the next year. These turbocharged engines were limited to 1.5 litre turbo engines, and 3.5 litre normally aspirated engines were also allowed. You had to pick either one.
The turbo engines usually made more power than the normally aspirated ones – 685 horsepower from a Honda RA168E turbo V6 limited to 2.5 bars of boost compared to Ford’s DFR 3.5 litre V8 making 585 horsepower.
