For the 85th time in history, the crème de la crème in the world of endurance racing gathers in the La Sarthe valley in France for what they call "Les 24 Heures Du Mans". This time around, it’s all about the Porsche vs. Toyota duel for the overall win while Ford seems to have a much harder job ahead if they want to go back to back in GTE-Pro. This year we’ve got again four classes and a 60-strong field with the biggest being LMP2, boasting a 25-car grid. There are only six LMP1 cars, five of which are the works hybrid machines, only one being a non-hybrid "light" prototype. GT cars make up the rest of the 29 vehicles, divided between GTE-Pro and GTE-Am. The former is made up of 13 cars, the remaining racers being entered in GTE-Am which also allows older spec GTE machinery.
