Audi inched closer to locking up the FIA World Endurance Championship on Sunday, as the German manufacturer edged out rival Toyota for top honors in the Six Hours of the Circuit of The Americas.
Allan McNish took the No. 2 Audi R18-etron quattro to a narrow 23.617-second victory over Stephane Sarrazin’s No. 8 Toyota TS030 Hybrid, which battled the diesel-powered hyrbid and led overall at stages of the inaugural round in Texas.
The key of the race was tire durability, as McNish and co-drivers Tom Kristensen and Loic Duval managed to double stint their Michelins, whereas the Toyota struggled to do the same.
