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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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 returns to rotary with RX-Vision Concept, crowd goes wild

Rotary! Forget everything for a second. Ignore the sleek styling, formed-by-wind sheetmetal, outrageously rear-drive proportions, and general ridiculousness of the sideview mirrors. And please be so kind as to ignore the poorly lit photos here – Mazda has a thing for drama. Concentrate instead on one fantastic phrase from the concept car press release: "next-generation Skyactiv-R rotary engine." The crowd here in Tokyo was downright frothing to get a look at the new concept car – hoping to catch a glimpse of the first evolutionary stage for a RX-9 sports car. The critical factor in that effort is of course the rotary engine. Mazda says that, while production of the powerplant is "on hold," the company has "never stopped research and development towards the rotary engine." The fact that the company has named the new engine gives us great hope that it exists in reality, and will be available for sale at some future date. The devil is in the details though, and there are precious few available at the Mazda stand. Other than a brief history lesson about Mazda's racing heritage, and fuzzy-vision talk about the future, we only have expectations to feed on. Oh, there's also a tiny press release, below. Related Video: HIROSHIMA, Japan—Mazda Motor Corporation unveiled the rotary-powered Mazda RX-VISION sports car concept at the Tokyo Motor Show*1 today. The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967. As the only automaker to mass-produce the rotary engine, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car. Over the years, the rotary engine has come to symbolize Mazda's creativity and tireless endeavor in the face of difficult challenges. While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine.

Marchionne now considering 'Plan B' partners for FCA merger

Okay Sergio, just stop. With the sting of rejection from General Motors CEO Mary Barra still fresh, Fiat Chrysler Automobiles CEO Sergio Marchionne is moving on and trying to find another automaker to merge with. FCA may not be giving up hope on a merger with GM, but that doesn't mean it isn't at least considering alternatives. Sergio's so-called "Plan Bs" include the Volkswagen Group, as well as smaller Asian outfits, like Mazda, Honda, Suzuki, and Hyundai. Bloomberg reports that France's beleaguered PSA Peugeot Citroen could as a sort of "fallback" option due to its relative lack of volume, an unidentified source claimed. There are, of course, problems with each option. According to Bloomberg, Volkswagen expects complete control of a company, but the Agnelli family, which holds a large portion of FCA stock, is loathe to relinquish its stake in the company. On top of that, VAG just isn't looking to make a deal right now. Mazda, meanwhile, is enjoying a new partnership with Toyota and Suzuki is partially owned by VW. Honda and Hyundai have never expressed any interest in a partnership with a western automaker. That kind of just leaves the French then, but even that remains a long shot. As Bloomberg tells it, PSA boss Carlos Tavares is still working on a turn-around plan, and would want at least another six months to execute before even considering a deal with FCA. And even then, Tavares hasn't given any indication that he's considering a pairing.
