The engine powering the all-new Mazda Prototype is the latest evolution of the Mazda SKYACTIV-D Clean Diesel that Mazda used to win nine races and the 2013 Grand-Am GX-class Manufacturers' Championship. While the engine itself is almost identical to that used in the Mazda6 last year, everything from the flywheel to the wheels is new. Managing almost 800 Nm (600 lb-ft) of torque will be the biggest technical challenge for the team. Over the course of the 2013 season, the team broke more than a dozen racing driveline components, but no stock Mazda parts!
