Mazda Skyactiv-D Prototype Racecar With John Doonan

Mazda made waves last year when it raced a Mazda6 equipped with a 2.2L Skyactiv-D engine in the Grand-Am series. Now, in the new TUDOR United SportsCar Championship, Mazda is moving up into the LMP2 class with the same 2.2L Skyactiv-D engine. Mazda's director of motorsports, John Doonan, explains the decision to move up in the ranks and what the company has planned for this season of racing.
