NEWS: Mazda to Campaign Skyactiv-D Powered Racer in USCC Series in 2014

We're still waiting for the official arrival of the diesel-powered Mazda6 in U.S. showrooms, but that's not stopping Mazda from actively campaigning diesel-powered race cars in the U.S. Following the success of the Skyactiv-D-powered Mazda6 in the Grand Am GX series, Mazda is entering a prototype race car in the 2014 TUDOR United SportsCar Championship.
The drivers for the USCC series will be Sylvain Tremblay and Tom Long for the #70 car, and Joel Miller and Tristan Nunez for the #70 car. As with the Mazda6 race cars, SpeedSource Race Engineering is lending its technical expertise with the hardware and development. Mazda will be the only manufacturer competing in the series with a diesel engine, showing its commitment to the technology.
The race-spec engine shares 51 percent of its components with the production diesel engine by parts count, and 63 percent by weight. Whereas the production U.S.-spec Skyactiv-D is expected to produce approximately 170 hp and 300 lb-ft of torque when it finally reaches showrooms, the race engine makes 450 hp and 580 lb-ft of torque. The racing engine is fortified with Mahle forged racing pistons and Carillo connecting rods. Power hits the track through an Xtrac six-speed sequential transmission, and a feathery curb weight of only 1984 lb. The Mazda USCC racer will make its public debut at the Roar Before the 24 test at Daytona, with its first race being the Rolex 24 Hour race on January 25-26.
