Ford Racing's new EcoBoost Daytona Prototype will compete in next year's inaugural TUDOR United SportsCar Championship, the merged series that brings American Le Mans and Grand Am together. And it will do it with one heck of a prototype car, from the early look of things. The EcoBoost V-6 prototype engine just set a new speed record at Daytona International Speedway.

The old record was set back in 1987 by Bill Elliott in a NASCAR cup car during qualifying for the Daytona 500, at 210.364 mph.

Ford's new Daytona Prototype smashed that record, recording a lap of 222.971 mph, completing the circuit in just 40.364 seconds.
riven by Colin Braun, the Michael Shank Racing prototype also set new FIA World Record times for the standing 10-km distance (202.438 mph) and the 10-mile distance (210.018 mph), pending certification by the FIA.

Of course, that's just one car turning laps on an empty track. Next year's challenges will be much more significant, with two prototype classes and three GT classes in the mix all at once.

Still, it looks like Ford Racing and its Roush Yates-built V-6 EcoBoost engine will do well for Michael Shank Racing if it holds up to the rigors of real-world racing.

Mazda Motorsports Announces Return to Elite Racing Prototype Program

November 14, 2013 (IRVINE, Calif.)—At Mazda, “Never Stop Challenging” isn’t just a catchphrase, it’s a company maxim. After nearly two years of planning, Mazda Motorsports will field a pair of factory-backed SKYACTIV-D Smart Diesel-powered racecars in the top Prototype Class for the 2014 TUDOR United SportsCar Championship (USCC), beginning with the Rolex 24 at Daytona on January 25-26, 2014. This is a major step up for Mazda, having won the 2013 Grand-Am GX Manufacturers Championship. Mazda will be challenging for overall race wins against the toughest sports car competitors in North America.

“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.”

Long-time racing partner SpeedSource Race Engineering, the team that oversaw Mazda’s GX-class championship in 2013, will carry responsibility to develop and run the cars on track. Additionally, Mazda also is in discussions with customer teams interested in the prototype class, as well as teams interested in developing the championship winning Mazda6 into a GT Daytona class car.

Sylvain Tremblay, Owner, SpeedSource Engineering noted; “As a racer, you always want to be in the fastest class. The development of the Mazda SKYACTIV-D was a great deal of work by Mazda and SpeedSource and it will be quite the task to take this to the front of the prototype class in only our second year of competition. Mazda and SpeedSource will have a busy November and December of testing as we prepare for Daytona.”

As part of its challenger frame of mind, Mazda is the only OEM racing with a diesel engine. The SKYACTIV-D Smart Diesel race engine is a true production-based engine and a carry-over from the development work done with the Mazda6 GX-class racing cars. The engine is 51 percent stock by parts count, and 63 percent stock by weight. Mazda chose this path as it is the most honest way to demonstrate the performance, quality, durability, and reliability of Mazda powerplants.

Driver line-ups and team partners will be announced at a later date. The cars will make their first public appearance at the “Roar Before the 24” test at Daytona, January 3-5, 2014.
