F1 is considering switching the sport's future engines to 1.6-litre V6 turbos in a bid to end the ongoing stalemate about future regulations. Ahead of a crunch meeting in London today to discuss engine regulations for 2013, amid disagreement between manufacturers over plans to move to 1.6-litre four-cylinder engines, it is understood that a final push has been made by the car makers to find a solution that is acceptable to all the sport's stakeholders. Sources have revealed that those behind-the-scenes discussions between the engine manufacturers have resulted in a plan for the four-cylinder plans to be dropped and instead 1.6-litre V6s to come into force from 2014 - one year later than the current change in regulations is planned to come into force. With the support of all the car makers, there is no reason why the teams would be against such a tweak to the engine regulations - especially as it would guarantee all the current manufacturers staying in the sport. And crucially for the FIA and its president Jean Todt, who has been adamant that F1 has to move to more environmentally-friendly rules, the plan includes sticking to the 'green' KERS technologies that were originally planned for the four-cylinder power units. The FIA said earlier this month that it would be willing to hold off the switch the four-cylinder engines if there was unanimous support of the competitors. If the V6 plan is received positively by the F1 Commission then it would go to the FIA's World Motor Sport Council for approval.
