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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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 taps Americas head as CEO to raise game in its biggest market

TOKYO — Mazda has named the head of its Americas operations as its next president and CEO after its current chief steps down in June, as Japan's fifth-largest automaker seeks to boost profitability in North America, its biggest market. The company said on Friday that Masamichi Kogai will step down and be replaced by current vice president Akira Marumoto, who now oversees operations in the Americas. The changes are effective June 26 after Mazda's annual shareholders' meeting. Mazda, which has global annual sales of around 1.6 million vehicles, has enjoyed a run of rising vehicle sales, expanding in markets particularly in North America, which accounts for nearly 30 percent of total sales. But as one of Japan's smaller automakers and a tiny player globally, it faces growing competition in the United States, where market growth has slowed, and where the company's profitability has sagged due to higher discounting and slowing demand for sedans. The maker of the MX-5 Miata roadster and the reputed Skyactiv gasoline engines also faces higher costs to stay competitive in an industry which is being disrupted by new technologies, including self-driving cars and electric vehicles. Marumoto, a 38-year company veteran with a background in engineering who described himself as having a "strict" work ethic and admitted to being "short-tempered" at times, previously led Mazda's corporate planning and product strategy divisions before heading its Americas operations. He said that growing sales and improving profitability in the North American market would be his biggest priority, along with expanding the company's brand image as an innovative car maker. "Given the rapid changes occurring in the auto industry at the moment it's often asked whether a small company like us will be OK," Marumoto, 60, told reporters at a briefing in Tokyo. "But before we even consider this we need to show our strengths, and what makes us different if we want to grow our brand." Kogai, who became Mazda's president and CEO in 2013, will be following the footsteps of his two immediate predecessors who also held the top job for five years each. He will still be with the automaker and become its chairman, the company said. Earlier this year, Mazda announced that it would invest in a new, $1.6 billion plant in the U.S. state of Alabama as a joint venture with Toyota.

Mazda will have a new rotary concept at Tokyo show, trying to bring it to production

Despite ending production of the rotary engine in 2012, Mazda has repeatedly insisted that it's still working on rotary engine tech, and it has continued to tease a potential future rotary car with concepts, the latest of which was the RX-Vision. The company even continues to file patents on rotary tech. It seems the company is continuing this pattern, since the vice president for Mazda's European R&D center told Auto Express that it has another rotary concept ready for this October's Tokyo Motor Show. According to Auto Express, the car expands on the groundwork laid by the RX-Vision concept. In addition to revealing the existence of the concept, the executive also reiterated the fact that there's still a team in Mazda working on the rotary engine, and people are still trying to make a business case for a new rotary sports car. Auto Express expects a production car could come in 2020. The news outlet also asked if the hypothetical car would be hybridized, and the Mazda executive didn't give much of an answer beyond it being possible, though he would prefer a purely rotary-powered car. We at Autoblog think a hybrid rotary of some sort would make the most sense. It would make for an impressive halo vehicle that could be used to promote future Mazda hybrids. This would also help with the business case side of things. An electric motor, or motors, would be highly complementary to the rotary engine as well. Electric motors produce oodles of torque from down low, which rotaries don't, and the rotary engine's high-rpm horsepower would compensate for the electric motors when they've started running out of power. Not only that, but using a hybrid powertrain could help a thirsty rotary engine meet fuel economy and emissions requirements while still producing plenty of power. A hybrid system is also more possible now that Mazda is teamed up with hybrid expert Toyota. Related Video:
