A diesel-powered Mazda 6 made history recently by winning the GX class of the Grand-Am Brickyard Grand Prix held at the Indianapolis Motor Speedway, making it the first diesel-fueled car to win on the legendary racetrack.
The win at Indianapolis was Mazda\'s fifth in a row and put them ahead of Porsche with only four more races to go on this year\'s 12-race calendar.
Powering the diesel Mazda 6 race car is a 2.2-liter Skyactiv-D clean diesel engine that is \"51% stock by parts count and 63% stock by weight,\" making it a true production-based engine.
According to the Japanese automaker, the last oil-burning car to compete in Indianapolis was a Cummins Engine Special, which took the pole for the Indy 500 race in 1952.
\"While this is our fifth win of the season--and fifth in a row--it is by far the biggest win to date,\" said Mazda North America motorsports director John Doonan. \"To win at Indy is every racer\'s dream and that dream came true for Mazda here today.\"
We knew there was a good reason why we loved the Mazda 6 diesel which we drove in Thailand earlier this year.
