Formula 1 engine design is set for a radical overhaul in 2013.
Multiple sources are reporting that turbocharged, four-cylinder 1.6-litre engines will be used from the 2013 season.
The smaller capacity engines – reduced from the 2.4-litre V8s used since 2006 – should be much more efficient than current units. Power output is likely to be kept at current levels and augmented by the use of Kinetic Energy Recovery Systems.
Teams also hope to attract more engine manufacturers to the sport through more road-relevant regulations. The recent departures of BMW, Toyota and Honda have left only four engine builders in F1: Mercedes, Renault, Cosworth and Ferrari.
The FIA intends to publish the definite 2011 FIA Formula One Sporting and Technical regulations following its World Motor Sport Council meeting on Friday. Further details on the future engine formula are also expected following that meeting.
