Audi are entering a long-tail R18 e-tron quattro at the second round of the FIA WEC, Spa-Francorchamps. The number 3 car, to be driven by Marc Gené, Oliver Jarvis and Lucas di Grassi, will be a new aerodynamic version of the R18, with a long-tail body work package. This new aero-package has been optimized for the high-speed Le Mans track and is not focused on absolute lap times at Spa. Audi will then determine if they are to use this new long-tail aerodynamic variant at Le Mans once they have compared specific race data from all three R18s.

The long-tail R18 e-tron quattro is expected to be a little compromised at Spa-Francorchamps but the data generated will prove useful for Audi in determing the viability of the aero-package in what will be an extended pre-event test for Le Mans.
