Mazda6 diesel to race at Rolex 24, team and drivers announced

Mazda is getting serious about showing off the Skyactiv-D turbo-diesel four-cylinder engine in the Mazda6. The automaker has just announced it will campaign three diesel Mazda6 racers in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona in a quest to walk away with the company's 24th class win. Mazda partnered with SpeedSource to develop the race version of the new sedan, with Japanese and American engineers lending a helping hand where needed. Meanwhile, Freedom Autosport and Visit Florida Racing/SpeedSource/Yellow Dragon Racing will helm teams of their own.
Each car will make use of a five-driver team for the 24-hour race on January 26. In the interim, you can check out the full press release below for more information as well as the full driver roster. Mazda says we can expect to see the No. 70 SpeedSource car under the lights at the 2013 Detroit Auto Show later this month, as well.

Mazda details diesel prototype at Daytona test

Diesel has without a doubt become the dominant fuel in the modern era of endurance racing. The 24 Hours of Le Mans has been won under diesel power for the past eight years running, as has every race in the FIA World Endurance Championship since its inauguration in 2012. Yet there will only be one diesel prototype entered in the top tier of the new Tudor United SportsCar Championship this year, and it belongs to Mazda.
The last Japanese manufacturer to win at Le Mans outright, Mazda has been gradually working its way back up the endurance racing ladder once again, following the example set by Audi with diesel power. Last year it campaigned a competition-spec Mazda6 Skyactiv-D in the GX class of the Grand-Am series, but rather than simply port over the existing racer into the new series, it's fielding a new prototype instead, just as it promised a couple of months ago. And now that prototype has hit the track for the first time, prompting Mazda to release its basic specs for the first time.
Tentatively referred to simply as the 2014 Mazda Prototype, the purpose-built racecar is testing this weekend in the Roar Before the 24, the official test session at Daytona that kicks off the racing season. It packs a 2.2-liter SkyActiv-D engine that's based heavily on the production version but tuned to produce 450 horsepower and 580 pound-feet of torque in race trim. Power is channeled through a six-speed sequential transmission from Xtrac, carbon brakes from AP and 18-inch racing slicks from Continental. With the Daytona-spec aero setup, it'll top out at around 186 miles per hour.

China's FAW now building all three Mazda6 generations

The Chinese auto market is one of the most interesting in the world to look at. Its automakers appear to still be figuring things out and remain open to experimentation. For example, at this moment, you can buy new copies of all three generations of the Mazda6 from showrooms there.
Mazda joint-venture partner FAW recently introduced the latest generation to China as the Mazda6 Atenza, according to Just Auto. Yet buyers still have the option of getting the previous generation as well, which is sold as the Mazda6 Ruiyi. Obviously, that isn't too remarkable - companies in the US have briefly sold two generations of the same nameplate simultaneously for brief points in the past, and the practice is much more common in developing markets. However, Chinese consumers still have the third choice, too - the first-generation model that dates back to the early 2000s, is still on offer, known simply as Mazda6.
While it would be hard to imagine selling three generations of the same models at once in the US, the idea is an interesting one. We enjoyed our long-term test of the latest generation, and the previous models weren't bad cars either, so provided there's a healthy difference in pricing and marketplace confusion is limited by differing names, we can see it working. If nothing else, it's a fascinating illustration of how broad China's developing auto market really is.
