Formula One cars will be powered by smaller, more fuel-efficient hybrid engines starting in 2013 under an agreement reached by F1 bigwigs.
The 2.4-liter, eight-cylinder engines that power existing cars will be replaced by much smaller 1.6-liter, four-cylinder turbo-charged engines with kinetic energy recovery systems (KERS), designed to reduce fuel consumption by as much as 50 percent.
Fuel consumption will be decreased by limiting the amount of fuel that flows into the engine, by reducing engine revs from 18,000rpm to 10,000rpm and by restricting fuel capacity.
