Audi reveals it has tested 2014 Le Mans challenger twice already

Audi has revealed that its 2014 World Endurance Championship challenger has already tested on two occasions.

The German manufacturer has confirmed that the new car, built to the forthcoming fuel formula P1 regulations, ran for the first time before the end of September and has subsequently tested for a second time.

Audi Sport boss Wolfgang Ullrich said: "The car has tested twice up to now. I could say more, but I don't want to."

It is understood that the testing has been undertaken by Marco Bonanomi, who drove a development R18 e-tron quattro at the Le Mans test day in June to gather data for tire supplier Michelin. The turbodiesel hybrid, which regenerates solely off the front axle, is due to be unveiled on Dec. 18.

Porsche began testing its 2014 challenger in June, while Toyota is not scheduled to run its take on the new regulations until next year.
