Three carmakers linked with post-2013 F1 forays

Three car makers have been named as potential candidates to enter formula one after the engine rules change in 2013.

Jean-Francois Caubet, managing director of F1 engine supplier Renault Sport F1, said "Volkswagen, Honda and Hyundai" could launch forays when the turbocharged four-cylinder power plants replace the current 2.4 litre V8s.
