The FIA's World Motor Sport Council (WMSC) has given its seal of approval to the newly-agreed V6 engine formula to be introduced in 2014 following a fax vote of its members. Teams had agreed prior to last weekend's European Grand Prix to delay the introduction of a new engine formula until 2014, and modify it from its previous 4-cylinder specification.

“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,” read an FIA statement on Wednesday.

“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.”

The original 1.6-litre 4-cylinder regulations had been agreed last year in an attempt to woo Audi into the sport as an engine manufacturer, but following the German manufacturer's withdrawal of interest teams moved to revert to a more conventional racing engine.

Although the architecture of the new engine has been agreed, discussions are ongoing to fix the rev limit, with the figure expected to be between 14,000 and 16,000 rpm.
