“This reopens our love affair with Le Mans,” said Jay Amestoy, Vice President of Mazda Motorsports, Mazda North American Operations (MNAO). “In 1991 we made history, winning with rotary technology. Now we're looking to return to the winner's circle with what we believe will be the most advanced and cleanest production-based powerplant the sport has ever seen. We'll do it in current Mazda style, with engines being available for sale to European and U.S. customers competing in the LMP2 class for both the World Endurance Championship (WEC) and the American Le Mans Series (ALMS).”

The engines are being developed jointly by Mazda Motor Corporation, Mazda North American Operations and SpeedSource Race Engineering. Dyno testing has already begun and on-track testing begins in late 2012.

The engines will be stock-block Mazda SKYACTIV-D 2.2-liter diesel four-cylinder, dual-stage turbocharged powerplants. 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.”

Mr. Masahiro Moro, Executive Officer in charge of global sales and marketing of Mazda Motor Corporation, made the following comment: “Mazda has fostered the culture of ‘never stop challenging.’ And it was this spirit that drove us through 18 consecutive years of racing at Le Mans, until we finally triumphed in 1991. In fact, it is this same spirit that laid the foundation for the portfolio of SKYACTIV Technologies. This was realized thanks to a number of technological breakthroughs. I am pleased that we will be supporting our private customers who are taking up the Le Mans challenge by supplying race engines as a customer-program based on our SKYACTIV-D CLEAN DIESEL.”

Planning and preparations continue for Dempsey Racing to become the first LMP2 customer for the Mazda SKYACTIV-D racing powerplant. Dempsey Racing is co-owned by racer/actor Patrick Dempsey.
