Frozen engines to stay in F1
"The plan, of course, was not so much a single engine, as for a single level of performance and a much cheaper engine. This will become increasingly necessary if we lose any more manufacturers," he told the official Formula 1 website.
Mosley believes frozen engines are here to stay, as long as the playing fields are leveled for all teams.
"I think we will end up with a frozen engine, regulated in such a way that independent teams can obtain inexpensive supplies," he said.
"I think we ought to try to have at least one independent outside engine supplier, because of the risk that we will lose another manufacturer or even two.
"The only problem with the original engine freeze was that in rectifying reliability problems, some teams appear to have gained somewhat in performance. We simply intend to ensure that the sporting contest remains fair."
