The World Motor Sport Council in a meeting today gave the green light to the proposed changes to Formula One car specifications for the 2013 season.
The new engines are to be turbocharged, but reduced in size from the current 2.4L V8's, to 1.6L four cylinder designs. KERS and other energy recovery devices are still expected to be maintained in an effort to make the cars as fuel efficient as possible.
However, despite the changes being agreed in principle, there is an option now available for the FIA to delay the introduction of the new style engines beyond 2013.
Other changes to be introduced include a reduction in the maximum nose height of cars, to increase safety in the event of a 'T-Bone' accident, and an increase to the weight of the cars.
