With less than two weeks before the Mazda Skyactiv Prototype makes its race debut at the 2014 Rolex 24 at Daytona, the Japanese Zoom-Zoom brand brought its diesel-powered racer to the floor of the 2014 Detroit Auto Show.

The red prototype marks Mazda's return to prototype racing, and will campaign the inaugural Tudor United SportsCar Championship using a 2.2-liter, SkyActiv-D diesel engine. With 451 horsepower on tap and 580 pound-feet of torque, the racer should stand up well against a field of gas-powered competitors.

Should the Skyactiv win Daytona, it'll be a coup for Mazda. The racer is running an engine with over 50 percent of its parts drawn from the oft-delayed production Skyactiv-D. Head up top for our full gallery of images of the new Skyactiv Prototype. The 2014 Rolex 24 will be run from January 25 to 26.

      They need to get "Skyactiv" on the car a few more times. Hope they do well. Hats off to Mazda - the one car company that continues to build interesting, fun to drive cars.

      If they aren't going to come to the US with the Sky-d they should just move on to an HCCI racer so they are actually advertising sellable technology.

          Forgive me for reading between the lines. This is starting to sound line Mahindra.

          Sky-D is delayed, but will be coming this year. One year late is not bad if they bring a solid as rock engine.

      Mazda had two of these at the recent 3 day test at Daytona. The fastest one had a best time which was beaten by over half of the slowest GT class in the field and cars from all other classes. Unless things improve big time, this could become the definition of bad marketing.

        Mazda disclosed a few days ago the trial runs at Daytona were solely for chassis tuning. They were not pushing for lap time

          Ha - if you are not pushing it, what is the chassis/aero tune good for?

        It would be surprising that a race team would field a car that off the mark. It's not like there aren't public statistics on Daytona lap times for different classes and racers. Giving them the benefit of doubt, they may not have been trying to test their top speed. It was a test day after all, not a qualifier.

          "beaten by over half of the slowest GT class in the field and cars from all other classes" - you don't test that slow unless you have a big problem.

      If they're really serious about going prototype racing, they should head overseas and compete with the big boys in the WEC. Swanning around in the TUSCC behind the DP's will do nothing for their brand image, IMHO. If they show up with a real LMP1 prototype, they'll never be allowed to race with DP's. Sorry, competing in a second tier sports car series just doesn't cut it....

        @Jan, Who's at fault if there is no LMP1 in TUSCC??? THEY are the ones who dropped it while whining like little girls. Had they instead embraced it and more closely aligned with WEC, then both series could have been better. The fact is they dropped the top tier of endurance racing and now they want us to respect them more? No, I don't respect running from competition. They could have made it more competitive by allowing the LMP2/DP cars to have larger tanks and make less stops. Instead they just bailed. I used to always go to Petite Le Mans...I didn't go last year when they dropped the LMP1s and now I have zero interest.

          You are wrong. LMP1 doesn't make sense without factories. If at least two full time factory cars showed up, then LMP1 wouldn't have been dropped. If you followed ALMS last year, LMP1 was a bad joke. Without factories, what's the point of LMP1? Last year there were two teams racing customer chassis with customer engines (using chassis that are effectively a version of LMP2 chassis) that were artificially unrestricted to be faster than LMP2 cars. How were they different from LPM2 and what's the point of this? If you want a class where teams push the envelope, you need factories.

      "Looks ready for Daytona". Well the pain is shiny and the decals are on straight if that is what you mean. I like Mazda and I hope they do well. With a car this new and different and their recent history with diesel race cars, I'm not laying any bets.

        "paint". Maybe that was a Freudian slip!

      I just lost interest in the whole thing today when they announced they are going to put restrictor plates on the DP prototypes because they were testing out too fast compared to the LMP2 cars. So....instead of making the LMP2 cars step up, they're going to make the DPs slow down? How pathetic. It was already a 2nd tier series and now they're slowing them all down? I'm not that bored...I can find something else to do next weekend rather than watch a second or even third class effort. How disappointing. They had a chance at a new start...and this is what they come up with? Call me when you get an LMP1 class back.
