FIA open to delaying new F1 engines

The World Motor Sport Council today approved the rules, which include aerodynamic regulations based on those currently in use alongside modifications designed to achieve the target of a 35 per cent reduction in fuel consumption. However, an FIA statement does allow for the possibility of the timing of the rules' introduction to be changed by vote.

Such a vote would be held by the WMSC, but only if F1's stakeholders, which includes the teams and engine manufacturers, demand it.

The statement read: "In consultation with the main stakeholders, and following the outcome of this consultation, a fax vote by the WMSC could be considered by 30 June latest to redefine the implementation date of these technical regulations."

Although the FIA approved the 2013 engine regulations last December, the likes of Ferrari and Cosworth have raised concerns about the cost of developing the power units. At the Turkish Grand Prix, FIA president Jean Todt insisted that the new powerplants would be introduced, although he did allow for a change in policy if some new evidence were to be presented.

The regulations as approved by the WMSC today include an increase of minimum weight to 660kg and a restriction on the height of a car's nose for safety reasons.

The statement listed the rules as follows:

- Power units will be four cylinders, 1.6 litre with high pressure gasoline injection up to 500 bar with a maximum of 12,000 rpm, with extensive energy management and energy recovery systems (now known as ERS), reflecting the decision taken by the WMSC in December 2010

- The aerodynamic regulations have been based on 2011 rules, with modifications in order to improve the aerodynamic efficiency: together with the power train rules, this will enable a 35 per cent reduction in fuel consumption

- The height of the tip of the nose will be limited to ensure better compatibility in a T-bone style accident

- A limitation on transmissions (gear ratios, number of gearboxes) in order to decrease costs

- The overall weight of the car must be no less than 660kg
