Mazda Motorsports announced earlier this week it would make its new SKYACTIV-D clean diesel engine available to racers of the new Rolex Sports Car Series GX class.
Mazda customers are already looking forward to working with the new unit.
"As a motorsports engineering firm, we love a challenge," said Sylvain Tremblay of SpeedSource Engineering. "Starting a new program with a stock-block SKYACTIV-D clean diesel engine gives us a wonderful opportunity."

The GX class is the latest addition to the Grand-Am family. It's a category made specifically for alternative technologies cars. GX competitors will be on track with both the Daytona Prototypes and the GT cars.
Mazda's SKYACTIV-D clean diesel engine boasts a 14:1 low compression ratio, a new two-stage turbocharger and a 5,200 rpm redline. Compared to Mazda's production 2.2L diesel, the SKYACTIV-D unit is 20% more fuel efficient and 10% lighter.
"This opens a new chapter in racing for us," said Jay Amestoy, vice president of Mazda Motorsports. "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 power-plant the sport has ever seen."
