Mazda Skyactiv-D racer first diesel to run at Indy in 60 years

While it may not be touting the old "Win on Sunday, sell on Monday" axiom we all know and love, Mazda recognizes that racing can only improve its cars. And so it's no surprise that the Japanese automaker is testing and refining its Skyactiv-D diesel engine by sending it out on various race tracks around the country - notably being the first diesel ever to compete at Daytona and the first to notch a Grand Am win at Road Atlanta.
Next up? Indy. It has been over 60 years since a diesel-powered machine ran at the Indianapolis Motor Speedway, and the Cummins-powered racer that competed in the 1952 Indy 500 with a 6.6-liter inline-six-cylinder oil-burner was a fast and brutal machine that set a new lap record in qualifying leading up to the race. Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to accomplish once again.
Mazda says that the diesel engine in its race car is pretty darn close to stock - 51 percent stock by parts count, and 63 percent stock by weight - which means the way it performs in competition is at least a somewhat meaningful way to the stock engine's durability in the real world. Check out the image of the Mazda6 Skyactiv-D racer posing alongside the 1952 Cummins above (click to enlarge) and feel free to peruse the press release below for the rest of the details.

White House clears way for NHTSA to mandate vehicle black boxes

At present, over 90 percent of all new vehicles sold in the United States today are equipped with event data recorders, more commonly known as black boxes. If the National Highway Traffic Safety Administration gets its way, that already high figure will swell to a full 100 percent in short order.
Such automotive black boxes have been in existence since the 1990s, and all current Ford, General Motors, Mazda and Toyota vehicles are so equipped. NHTSA has been attempting to make these data recorders mandatory for automakers, and according to The Detroit News, the White House Office of Management Budget has just finished reviewing the proposal, clearing the way. Now NHTSA is expected to draft new legislation to make the boxes a requirement.
One problem with current black boxes is that there's no set of standards for automakers to follow when creating what bits of data are recorded, and for how long or in what format it is stored. In other words, one automaker's box is probably not compatible with its competitors.

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.
