» New engine rules to attract new manufacturers?

Up to three carmakers have been named as possible candidates to enter – or return – to Formula 1 in the wake of the sport’s new engine rules that will come into effect in 2013.

And while Bernie Ecclestone might not be a fan of the new 1.6-litre four-cylinder turbocharged engines that the FIA is backing to make the sport ‘greener’, the managing director of Renault Sport F1, Jean-Louis Caubet, believes that this can only be good for the sport.

The Frenchman believes that “Volkswagen, Honda and Hyundai” could enter the sport some time after 2013, believing they will wait a bit to evaluate the success of the new rules before making a commitment to join.

“I don’t think they will come in the first year, because that would be difficult for a car manufacturer,” he said in an interview with motorsport-total.com. “Maybe later.”
