The FIA today confirmed their intention for a greener Formula One with the introduction of radical new engine regulations from 2013.
At the final meeting of the year of the World Motor Sport Council, held in Monaco, the body have rubberstamped plans that will ensure the sport becomes far more environmentally friendly.
Following dialogue with the four engine manufacturers - Ferrari, Renault, Mercedes and Cosworth - the powerplants will be 1.6-litre, four-cylinder units with high-pressure fuel injection, and with a maximum 12,000rpm.
The quartet now have 27 months to deliver the new powerplants that will replace the current 2.4-litre V8s.
VW/Audi, who had apparently been awaiting today's announcement with some interest, may also now come into the reckoning as an engine supplier in light of the FIA's forward-thinking plans.
According to the FIA the new engines will deliver a 35% reduction in fuel consumption and will feature extensive energy management and recovery systems, yet maintaining current levels of performance.
From next year F1 is already due to see the re-introduction of KERS (kinetic energy recovery system), a device that stores energy from braking and converts it into power used to boost acceleration.
According to motor sport's world governing body, their announcement "underlines the FIA's commitment to improving sustainability and addressing the needs of the automotive industry."
In a further move to cut engine costs, from 2013 drivers will only be allowed to use five per season - the limit is currently eight - with that figure cut to four from 2014.
