The FIA have confirmed that the new Formula One engine formula as of 2014 will consist of turbocharged V6 engines with a capacity of 1600cc maximum. The new engines will also include energy recovery systems, although specifications on those are not yet clear.
The statement read: "Following a fax vote by its members, the World Motor Sport Council has ratified the engine regulations recently drawn up in consultation with the main stakeholders in Formula One.
"The new power plant will be a V6 1.6 turbo unit with energy recovery systems. This new formula will come into effect as from the start of the 2014 FIA Formula One World Championship season."
Teams agreed before Valencia to go for this type of engine in favour of the earlier proposed 1.6l inline 4-cylinder.
