Next season Cosworth will be supplying their V8 engines to new F1 entrants, Campos Meta 1, USF1 and Manor, but with Cosworth’s engines performing at 18,000rpm, there have been doubts that is lack the power to keep up with the big boys.

With that FIA has granted dispensation to run them up to 20,000rpm, but Cosworth has scrapped the concession as Cosworth’s Chief Executive Officer, Tim Routsis believes their engine is up to par.

He dismiss such claims and said their engines will not make the new teams will not be at a disadvantaged by the reduced output of the engine. It seems their main concern is more of the capping of the number of engines per car, which is five for next season.

Routsis was quoted, “We were confident that the engine in the return form would be utterly competitive providing we started early enough. I think the teams will not be any less competitive as a result of having a re-tuned engine. If anything, I think there are benefits to be had from reduced rejection of heat to oil, so radiators can get smaller, the drag goes down. Also, as an engine spins faster it consumed more fuel to overcome frictions, so by lowering the revs were are also going to improve the fuel efficiency. Our position is that we are completely happy with this concept of reducing the revs to 18,000rpm but we only have a finite amount of time before we have to deliver engines. There is not enough time for us to do a re-tune and extend the life of the engines. So we need to stay with the agreed number of eight engines.”
