Mazda Motorsports announced that it will supply racing versions of its new SKYACTIV-D clean diesel engines to customer teams competing in GRAND-AM’s new GX Class for advanced/clean technologies, beginning with the 2013 season.

“This opens a new chapter in racing for us,” said Jay Amestoy, Vice President of Mazda Motorsports, Mazda North American Operations (MNAO). “We’ve won with rotary technology, and now we’re looking to again put our customers in the winner’s circle with what we believe will be the most advanced and cleanest production-based powerplant the sport has ever seen.”

The engines will be stock-block Mazda SKYACTIV-D 2.2-liter diesel four-cylinder, dual-stage turbocharged powerplants that, according to John Doonan, MNAO’s Director of Mazda Motorsports, “will deliver outstanding performance and fuel economy coupled with the kind of quality, durability and reliability needed to produce great street cars and win endurance races.”

Mazda remains the only Asian auto maker committed to bringing modern clean-diesel technology to the United States.
