Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:

2017 Mazda CX-9 packs turbo power, fresh style

After nearly a decade of sales, Mazda finally introduces the second-generation CX-9 crossover. It delivers a comprehensive interior and exterior overhaul, blessing the CX-9 with a powerful, efficient Skyactiv powertrain, and instilling even more of the sporting character that makes Mazdas so darn charming. Like every other vehicle in Mazda's catalog, the CX-9 now wears the handsome, suave stylings of the company's Kodo design language. We think it looks great, but feel free to disagree in Comments. The second-generation CX-9 is the perfect example of Mazda's growing interior design prowess. As is so often the case, it's not so much the style but the choice of materials that stands out. Nappa leather can be paired with real Japanese rosewood and aluminum accents to craft a cabin that feels far more expensive than what you might expect from Mazda. The quality is impressive, even on the pre-pre-production prototypes we tested (drive impressions coming soon). The other headline, aside from the gorgeous interior, is the powertrain. The heart and soul of the operation is a new 2.5-liter, turbocharged Skyactiv engine. Although it only produces a modest 250 horsepower, that figure is complemented by a whopping 310 pound-feet of torque. Importantly, torque is easy to access in the lower part of the rev range, with peak twist coming in at just 2,000 rpm. It drops off rather suddenly north of 4,000 rpm, but as Mazda tells it, most consumers rarely venture above that figure. Mazda expects the CX-9's core market to be perfectly happy with the robust low-end output. A six-speed automatic is responsible for doling out that grunt, and is meant to play nicely with the same i-Activ predictive all-wheel-drive system found in the CX-5 (although the two cars don't share any AWD components). Using 22 different sensors, the system measures road conditions 200 times every second and will even send up to half the engine's power to the rear axle. The entire car, meanwhile, rides on the same Skyactiv architecture as the CX-5 and Mazda6, meaning a multi-link rear suspension has been paired with MacPherson struts up front. Eighteen-inch wheels will be standard, although 20s will also be on offer. You can expect to hear much more on just what the new CX-9 is like to drive next week. Until then, enjoy the official images from Mazda, and keep an eye open for live shots from the LA debut, headed your way soon.

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.
