    Audi shares details on its new turbo diesel V6 from the R18 race car

    We all know LeMans is coming up in around 6 weeks and that this is the premier event for the Audi brand. Not hard to see how much emphasis they put on it with their dominance of the race in the past decade. Well, changing regulations have forced Audi to change their motor. The LeMans race car no longer has a twin turbo diesel V10 but instead now will have a single turbo 3.7 liter V6. The regulation changes are designed to prevent the diesels from having such a large advantage. Why? Fuel efficiency is a huge part of the 24 hour race. This 3.7 liter motor has put up a strong showing so far with a claimed output of around 540 horsepower which powered the R18 to the two fastest laptimes in testing.

    They were faster than Peugeot in testing so we will see. The R18 looks WAY strong but actually is slower than the cars with the V10. New regs have slowed cars down a little bit.

    I assume the motor is restricted in the same way to the same size. It was a 5.5 V12 turbo diesel...

    Well it won't have that engine anymore just like Audi won't have their big twin turbo motor anymore.

    Some more details:

    The brand with the four rings set with diesel engines since 2006. Because the regulations of the organizer "Automobile Club de l'Ouest (ACO) from this year requiring smaller engines as before, Audi opted for the compact 3.7-liter V6 TDI with over 540 hp. This is around 25 percent lighter than the V10 TDI power unit of the predecessor model, the R15 TDI. The Ingolstädter have deliberately chosen instead of the six-cylinder V8 - as the rules would allow them - because, this smaller unit's engineers regarding the electrification and energy recovery for the future "all options are open late.
