The World Endurance Championship made its one and only stop in North America for the 2015 season, pairing with the TUDOR United SportsCar Championship for a big sports car weekend at the Circuit of the Americas. In the end, Porsche would be smiling the biggest with dominant performances in two of four classes.
In the LMP1 class, Porsche dominated from the outset in qualifying, and looked set to take home a one-two finish with the #18 team leading the #17 squad. However, drama with just thirty minutes remaining in the race when the #18 car pulled into the garage for an electrical issue and was done for the night, handing the lead to their sister car. The #17 would take home the class and overall win, with the #7 and #8 Audis running two-three.
Meanwhile, in LMP2, the battle was set to be between G-Drive Racing and KCMG coming down to the finish. While the KCMG would battle through pit road miscues throughout the night, they would come up just short, giving the win to the #26 team from G-Drive Racing of Sam Bird, Julien Canal, and Roman Rusinov.
GTE-Pro class would never be in doubt by comparison, with the Porsche Manthey teams running one-two throughout the six hours. It would be the #91 team of Michael Christensen and Richard Lietz that would take the class win, with the #92 car coming in second.
The big American showdown was in GTE-Am during the six hours, where Dempsey-Proton Racing, led by Americans Patrick Long and movie star Patrick Dempsey, would challenge for the class win. After contending early, the team would slip back to fourth place finish, with SMP Racing taking the win in their team Ferrari.
With the WEC 6 Hours of Circuit of the Americas in the books, only three races remain in the sports car series calendar. The next race comes up on October 11 as all four classes do battle on the Fuji Speedway for six hours in Japan.
