After many years of being winless at the Indianapolis Motor Speedway, Mazda finally stood at the podium at what is considered as the most famous racetrack in the world after the #70 SpeedSource Castrol Edge Mazda6 SKYACTIV-D Clean Diesel piloted by Sylvain Tremblay won the GX class in the Grand-Am Brickyard Grand Prix.
The victory was the fifth consecutive win for the all-new Mazda6, allowing Mazda to take over the lead from after eight of 12 races in the GX manufacturers championship race. Just like what has been happening this season, the Grand-Am Brickyard Grand Prix became a three-car battle between Mazda and Porsche, with both brands having their taste of the lead.
SpeedSource Mazda’s Tremblay took the lead with 47 laps remaining in the three hour race, and never gave it away afterwards.
The race at Indy was the third and final round of the Grand-Am North America Endurance Championship. The first two rounds were the Rolex 24 at Daytona and the Sahlen’s Six Hour at Watkins Glen. The SpeedSource Mazda won the team championship for the GX class. This was the second year that sports cars bannered a featured race at the Indianapolis Motor Speedway.
This was also the first time a diesel-power car won at the race track known for the very famous Indianapolis 500. The Cummins Engine Special, however, was the first diesel to win the pole for the Indy 500 in 1952. The SKYACTIV-D Clean Diesel engine the powers the Mazda6 is a true production-based engine. It is 51 percent stock by parts count, and 63 percent stock by weight.
