Mazda Motorsports will be campaigning SkyActiv-D Smart Diesel-powered racecars in the top Prototype Class for the 2014 TUDOR United SportsCar Championship (USCC).

The race cars will make their debut at the Rolex 24 at Daytona next year on January 25-26. Having already captured the 2013 Grand-Am GX Manufacturers Championship, the Japanese automaker is hoping to have success against some of North America’s toughest sports car competitors.

SpeedSource Race Engineering, the same team that oversaw Mazda’s GX-class championship this year, will be charged with developing and running the cars in the USCC series. Mazda is also in discussions with customer teams that may be interested in competing in the prototype class as well as some interested in fielding a Mazda6 in the GT Daytona class.

Mazda will be the only OEM racing with a diesel engine and will use a true production-based engine in its race cars. According to the Japanese automaker, the engine is 51-percent stock by parts count and 63-percent stock by weight. Driver lineups and team partners will be announced at a later date.

“This is the most significant step Mazda has taken towards returning to the global racing stage since our overall victory at Le Mans in 1991,” said John Doonan, director of Mazda Motorsports. “And thanks to our SKYACTIV-D Mazda6 racecars winning nine of 12 Rolex GRAND-AM GX races and the GRAND-AM GX Manufacturers Championship this year, we’re confident that our two prototype cars will challenge the best North America has to offer.”
