In the 2007 24 Hours of Le Mans , the first place car was a Audi R10 TDI , with a V12 diesel engine . The second place car was a Peugeot 908 , also with a V12 diesel . At the Paris motor show 2006 Peugeot presented a new racing car , as well as a luxury saloon concept car , both called 908 HDi FAP and 908 RC and fitted with a V12 Diesel engine producing around or even surpassing 700 P. This took part in the 24 Hours of Le Mans 2007 race , with a podium finish and very competitive performance , coming in second place after the similarly-conceived Audi R10 TDI V12 Diesel originally developed for the 2006 season .
