Audi will be racing a “long-tail” version of the R18 e-tron Quattro World Endurance Championship car, in addition to its two other entries, at the Spa race in Belgium. The information Audi gathers there will be used to modify the cars that will be competing in the 24 Hours of Le Mans race in June.
The idea is not to see which variant is the fastest overall, but to see which sections of the track the different cars are fastest on.
The R18 e-tron Quattro is powered by a 3.7-liter turbo-diesel V-6 engine, producing 510 horsepower and 626 pound-feet of torque at the rear wheels. Additionally, it features an electric motor/generator at the front axle, along with an electric flywheel that stores kinetic energy for on-demand power.
The race at Spa should be an interesting one to watch, even more so because of the experimentation by Audi.
If you need a little inspiration to watch the race, check out the video below, posted by Audi driver Andre Lotterer on his twitter account (“I feel like a jet pilot”), of the R18 doing some incredibly fast runs at Monza.
