LIVE, beginning Saturday, 1:45 p.m. (EST), witness the start of a new chapter of Mazda Motorsport, as Mazda factory drivers attack the 2014 Rolex 24 at Daytona from within two all-new SKYACTIV-D® clean-diesel Mazda Prototypes.
This first race of the new TUDOR United Sports Car Series Championship marks the 52nd anniversary of the Rolex 24 at Daytona—a race Mazda factory drivers have won 23 times, in class.
Behind the wheels, this time around: Sylvain Tremblay, Tom Long, Joel Miller, Tristan Nunez, Tristan Vautier, and James Hinchcliffe.
Their top-flight Prototype-class Mazda machines are powered by SpeedSource Race Engineering's latest tuned versions of the Mazda SKYACTIV-D® clean-diesel engine that helped earn Mazda the 2013 Grand-Am GX-class Manufacturer's Championship, after nine straight wins.
And like their predecessors, these Mazda SKYACTIV-D® race engines are also fueled by the same "chicken guts" clean-diesel synthesized by Dynamic Fuels from food processing remnants, in a renewable, 100% carbon-neutral process.
