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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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.

Mazda CX-5 in auto-brake accident on Japanese test drive

As we slowly march towards a world where our cars will drive for us, there will be mishaps. Systems will act up, not behave has intended or we'll simply forget to turn them on. We all remember when Volvo tested the S60's City Safety system. Now Mazda has had an issue of its own.
During a test of a Mazda CX-5's Smart City Brake Support on a dealership lot in Japan, a prospective customer and a dealership employee were injured when they hit a urethane barrier used for testing the system. According to Bloomberg, which spoke with the Saitama Prefectural Police, the impact with the barrier left the customer with an injured neck while the dealership employee suffered a fractured arm. Considering the injuries, we imagine this wasn't a small barrier.
"For any safety function, it's impossible to be 100-percent free of accidents. These technical functions aren't always the easiest to understand," IHS Automotive auto parts analyst, Hiroshi Ataka told Bloomberg.

Xcar tries to figure out what makes the Miata so great

Over the past 25 years and 3 model generations, the Mazda MX-5 Miata has shown that you don't have to be the best to be a massive success. The little, Japanese roadster has never been the absolute peak of automotive performance, but it's precise handling, good reliability and frugal running costs have helped make it a star. Autoblog recently tried to give you the experience of driving one on video, and now Xcar Films has made its own in an attempt to show what makes this droptop an icon.
As Xcar puts it, the Miata isn't the world's best sports car, but it is the world's favorite. When they were originally designing the roadster, Mazda's engineers took everything that made British droptops from the '60s great, and junked all of the stuff that made them a terror to own. The result was a car that would start up everyday with no fuss and get drivers wherever they needed to go with a huge grin on their face.
The fourth-generation Miata is imminently on the way for its September 3 unveiling, and the very early rumors indicate that Mazda doesn't plan to rock the boat too much with the latest one. It supposedly rides on a longer wheelbase and wider track but with the weight trimmed by over 200 pounds. Check out Xcar's video for a primer on MX-5 history and why the automotive world loves this little roadster.
