Aside from Audi gaining from Peugeot's absence, they will also gain from Toyota's decision to only participate in a few of this year's LMP1 races and the fact that old timers Porsche will only be re-entering the fray in 2014. So expect a very lopsided Le Mans LMP1 category for the next few years people. And furthermore, Le Mans without a proper French manufacturer/team is somehow a sad thing too.
It is actually quite sad to see Peugeot pull out of Le Mans are they have been doing quite well and was the second manufacturer to compete in the Le Mans with a diesel powered car – the 908HDi FAP is a diesel powered car with a 5.5liter V12 with over 700bhp and 1,200Nm torque. It actually showcases what could be done to a diesel engine and come to think of it, road cars benefit from this trickling down of technology.
So it is a shame that Peugeot pulled out actually. While participating in motorsports actually allow manufacturers to develop cars faster it also drains resources fairly quickly. It seems that marketing needs to take priority for Peugeot for the time being as in order to participate in motorsports, it needs to make some money first. It is indeed a logical yet fairly vicious circle that cannot be broken.
