Mazda To Roar At TUDOR United SportsCar Championship With Skyactiv

Mazda daytona2

Mazda has long believed in promoting from within, including filling those rare ‘factory team’ driver slots.  Mazda Motorsports will field a pair of factory-backed SKYACTIV Technology-powered prototypes in the 2014 TUDOR United SportsCar Championship.  Behind the wheel will be the four drivers who delivered nine race wins and the 2013 Grand-Am GX Manufacturers Championship for Mazda.  Sylvain Tremblay and Tom Long will share the #70 car while Joel Miller and Tristan Nunez will co-pilot the #07.  The team took their first public laps at the annual pre-season “Roar Before the 24” test at Daytona International Speedway recently.  This test is for the season opening Rolex 24 Hour race on January 25-26.

As part of its challenger frame of mind, Mazda is the only car company racing in the TUDOR Championship with a diesel engine.  The SKYACTIV-D Clean 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.
