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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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 sells 10 millionth car in the US, does something special

When Lauren Carter of Glen Ellyn, IL was in the market for her first car, she went for a Mazda3. Not a bad choice, but not necessarily remarkable on the surface. After all, Mazda sold 123,361 of them here last year alone. What she didn't know was that the car she bought was the 10 millionth Mazda had sold in the US over the course of its 43-year history here, since selling its first rotary-powered R100 here in 1970.
Rather than let the occasion pass with nothing more than a press release (like the one below), Mazda gave Lauren a brand-new 2014 Mazda3 to replace the 2013 model she had bought. Which is a nice gesture, of course, but also enables Mazda to hold on to the landmark 10,000,000th car in its heritage collection.

We go Unplugged to celebrate Mazda Miata Month

Chances are good that you, loyal Autoblog reader, have long since chosen to follow us on Twitter and 'like' us on Facebook. (If you haven't, feel free to take a second and do so right now.) Anyway, if you're one of our social media posse, you might have already heard that we're smack dab in the middle of Miata Month. We've gotten Mazda to loan us a couple of MX-5 Miatas, allowing us to say a protracted, tear-filled goodbye to the current generation (NC) of the beloved roadster, just before it exits stage right and ushers in the next generation.
You'll see a few more Miata Month items here on Autoblog after we've said our final farewell, but we absolutely wanted to make sure we created some great video evidence of our month, as well. Right down below, then, in its unfiltered-audio splendor, is the Autoblog Unplugged version of the 2015 Mazda MX-5 Miata PRHT. Your author had a pretty great time wringing out the roadster for the creation of our short vid, and we really hope you dig listening along.
