2014 Mazda Skyactiv Prototype looks ready for Daytona

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.

Bauer Catfish is a Miata-based trackstar in the making [w/videos]

We're not trying to make a joke here. The creation you see above really is called the Bauer Catfish, and while the name is about as attractive as your average bottom feeder, the car itself is built on a sexy notion. Take the mechanical bits of one 1990-2005 Mazda MX-5 Miata, add in a tube chassis for as little weight as possible, complete with some custom body work and go forth. Bauer says the finished product weighs in at just 1,550 pounds, and the company will be happy to pull the stock four-cylinder to drop in a healthy General Motors LS V8.
The pre-production prototype shown above competed in last year's 25 Hours of Thunderhill, finished the race and earned a spot on the podium in the "anything goes for sports racers" ESR class. Very cool.
If you're looking for a dedicated track car, it may not get any better than this for the money. Expect to pay around $13,900 depending on options, plus the cost of your donor Miata. That's a good sight cheaper than a used Chevy Corvette Z06 and likely to be quite a bit more fun. After you're done watching it in action in the brief videos below, check it out over at Bauer Ltd.

Mazda6 GX Grand-Am racer goes where no diesel sedan has gone before

There has never been a four-door diesel sedan in the Grand-Am series, until now: The blunt, bewinged grille of the Mazda6 GX has blown right through that wall. It's said that racing improves the breed, but usually the breed has gone on sale when the racing begins. One of the unusual aspects of the Mazda6 GX, on the other hand, is that while the diesel won't go on sale to the public until later this year, it will already have tasted racing blood by the end of the day. That kind of reversal is more likely found with super coupes like the Lexus LFA and Honda NSX.
Mazda has taken class wins at Daytona's 24-hour race a whopping 23 times since 1975, most recently in 2010 with the RX-8 in the GT class. This year the Hiroshima company decided to show off its SkyActiv technology, then turned things up to eleven by opting for its SkyActiv-D instead of the more conventional SkyActiv-G gas engine to run in the new GX class. It will be joined by competitors like the Lotus Evora and Porsche Cayman in the class, nevertheless, at 2.4 liters, it's the smallest engine on the grid.
Time has not been a friend, either - Mazda said that the first five SkyActiv-D engines off the production line went to Speed Source in Coral Springs, Florida, the company that preps Mazda's race vehicles. Still, race driver Jonathan Baumarito on the #70 car said that although the engine's been on the dyno since February of last year, it's only been in the car for about a month and there have been only a couple of test days.
