Audi has released today more information about the revised R18 e-tron quattro set to participate in this year’s legendary Le Mans endurance race. Audi’s engineers worked hard to create two body versions of the racer, one that has a minimal aerodynamic drag suitable for Le Mans and the other for the seven races in the World Endurance Championship (WEC).
Audi Sport’s chief of aerodynamics says “nearly all the relevant areas of the bodywork have been optimized”, including the front area where one of the versions has the fenders with openings on the inside rather than on top. In addition, the body of the second variant is now flush with the rear wing and makes the most of the car’s 4650mm length, whereas the high-downforce derivative boasts a shortened body.
Audi also modified the tailpipes of the Le Mans version which don’t exit to the left and right of the central fin as they exit at the body surface above the rear diffuser. The German marque says they had to resort to a second body version because of the unusual track characteristics found at Le Mans which combines long straights with lots of fast turns.
The latest evolution of the Audi R18 e-tron quattro is the most fuel efficient ever without having to compromise the vehicle’s performances.
