Mazda rumored to bring rotary-powered RX-9 concept to Tokyo

Stop us if you've heard this one before: Mazda will bring a rotary-powered sports car to the next big auto show. Okay, so we stopped for a second, but the show must go on. Following an official teaser image (shown above) late last month, Motoring.com.au has what it claims are renderings of the curvy, two-door coupe – called the RX-9 – that Mazda will bring to the Tokyo Motor Show later this month. The images show a far softer styling than Mazda's current crop of Kodo-inspired vehicles, while the overall look screams of a modern-day Cosmo Sport, the Japanese brand's first rotary-powered vehicle. And though that connection alone might be enough to justify whisperings of a successor to the RX-7 and RX-8, Motoring claims there will be an even more overt sign of this concept's power source. "Look to the Cosmo Sport," an inside source told the Aussie website, signaling that the Mazda stand would feature the vintage two-door. "The Cosmo has no earthly reason for being there unless..." The rotary rumor, if it comes true, won't exactly be what we're use to. While Motoring brings up the previously reported 16X – a 1.6-liter two-rotor – it builds on our 2013 report. According to the Aussies, the new engine could feature a two-stage electric turbocharger, be paired with a hybrid powertrain, offer up to 450 horsepower, and we're guessing, be hilariously complicated. Joking aside, it sounds like Mazda's goals here are admirable. A rotary-equipped sports car that could counter the 1.3-liter RX-8 engine's appetite for fuel and improve on its mediocre low and mid-range torque would be interesting indeed. As for those renderings, Motoring has front and rear three-quarter images. Comparing the rear with our original teaser leaves the look open to interpretation, but after seriously upping the exposure on the teaser (thanks Photoshop), the taillights and overall profile shape look to be a spot-on match. In front, the long hood shares some Kodo elements, like the headlights and grille, but its undeniable coupe shape – a long hood and very short deck – are far more organic and, dare we say, calm, than Mazda's other vehicles. You can take a closer look at the renderings over at Motoring's website. Do that, and then head back and let us know what you think of these RX-9 rumors. Is Mazda finally going to be bringing a rotary back to market?

Mazda: Penn & Teller

Mazda turned to magic to highlight its refreshed CX-5, bringing in Las Vegas staples Penn and Teller to saw the CUV in half. The glitzy spot has a very Sin City feel to it, although considering some of the ads we've seen tonight, it's short on shock value, humor and heart-tugging imagery. Have a look, though, and let us know what you think.

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.
