When Audi decided to design a new car that would be able to compete at the Le Mans 24-hour race they knew that they had to draw from inspiration of previous winners, which is where the R8, R10 TDI and R15 TDI come in. What the German automaker came up with was the R18, which has a powerful 3.7-liter V6 TDI engine.
There are a number of races where aerodynamic efficiency is very important, F1 is one and the other is LeMans. However, Audi has decided to go with a new concept with the R18, as it will feature a closed coupe design. Darren Quick from Gizmag has elaborated on this further, as well as offering details on some of the other design features.
Picking up on that engine mentioned earlier, we have managed to get more of an insight from the Audi Press release from Autoblog. Diesels have never been as they are now; they are producing more power and are now much cleaner, and in most cases provide much more torque than a standard gasoline engine.
You will also notice that Audi has decided to go with the smaller engine, we are not sure of the reasons, but we have seen from Formula 1 that smaller can still offer a great deal of power – those cars can still hit over 200mph on the straights. Visit Autoblog for a host of photos of the new R18.
