Audi went 1-2 in Saturday night FIA World Endurance Championship Six Hours of the Circuit of The Americas, overcoming both weather and other manufacturer pit strategy to score its second straight FIA WEC win.
Neither of the Audi R18 e-tron quattros went off in the second hour rain deluge that caused a 50-minute red flag. Then on opposite tire strategies, the No. 2 Audi on Michelin’s ungrooved intermediate hybrid tire took the edge over the No. 1, on the standard wet.
The No. 14 Porsche 919 Hybrid had the lead heading into the final hour thanks to one less pit stop, but a power less coupled with Marcel Fassler extending his lead in the No. 2 Audi prior to a final splash of fuel allowed the Audi to seize the advantage.
Fassler, Andre Lotterer and Benoit Treluyer followed up their Le Mans win with the win at COTA, ahead of the sister No. 1 of Tom Kristensen, Lucas di Grassi and the returning Loic Duval.
The No. 8 Toyota TS040 Hybrid was third in the hands of Sebastien Buemi, Anthony Davidson and Nicolas Lapierre, the latter turning in a great comeback drive after being one of several cars that went off in the rain.
Other class winners were KCMG (LMP2) and Aston Martin Racing (both GTE-Pro and GTE-Am).
After a three-week break, compared to a three-month break, the FIA WEC is in action next at Fuji, Japan on October 12.
