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:

100th Anniversary 2020 Mazda MX-5 Miata announced for sale in the U.S.

The 100th Anniversary Special Edition Mazda MX-5 Miata will be sold in the U.S. When Mazda initially announced all of its 100th Anniversary vehicles, U.S. availability was still questionable for Mazda’s roadster. ThatÂ’s no longer the case, as the company announced all the details on the car today. ItÂ’s going to be based off the Grand Touring trim, so itÂ’s outfitted with the maximum amount of equipment. Those that purchase one will be able to choose from either the traditional soft top or an RF version. The soft top is red, while the RF gets a black-painted roof. Every last one of them will be painted in Snowflake White Pearl Mica and feature red accents throughout. Mazda plans on making them with both manual and automatic transmissions. We asked how many will be available, but Mazda told us it isn't sharing that information yet — limited edition Miatas tend to sell out quick. On the exterior, the front fender gets a “100 Years 1920-2020” badge. Wheel center caps for the 17-inch dark-silver wheels also have the 100th Anniversary logo on them, but thatÂ’s it for the exterior. The inside is where Mazda really had its fun. Full red leather seats and red carpeting pop and make this interior unlike any other Miata on sale today. Both the headrests and the floor mats feature 100th Anniversary logos, and as a finishing touch, Mazda put together a special 100th Anniversary key fob that is embossed with the same logo and comes presented in a special edition box. Since this car is based on the Grand Touring, you get performance goodies like Bilstein dampers, limited-slip differential, front shock tower brace and sport-tuned suspension. Of course, it needs the proper six-speed manual transmission to get all of that. From a cost perspective, you only pay a small price for the special edition car. With the soft top and six-speed manual, it totals $33,615. ThatÂ’s just $1,000 more than an identically-equipped regular MX-5 Grand Touring. An RF with the manual totals $36,370, which again, is just $1,000 more than the standard RF. The difference is the same with the automatic transmission Miatas. A soft top auto costs $34,140, while an automatic RF costs $35,695. Mazda says the special edition Miatas will be arriving in dealerships “later this year.” Related Video:

Mazda's rotary-engine range extender could serve as an emergency generator

GENEVA — Mazda has some pretty exciting powertrain technology in the works, particularly its Skyactiv-X spark-controlled compression-ignition engine, but also the upcoming range-extended electric vehicle with a rotary engine. It offers the possibility of electric transportation with a distinctly Mazda way of getting electricity from gas when charging isn't an option. But we learned that Mazda has some other ideas for the rotary range-extender beyond transportation, and even beyond gasoline. In talking with Ichiro Hirose, Maza's managing executive officer for powertrain and vehicle development, product planning and cost innovation, we learned that the company is exploring the powertrain's potential as an emergency generator. Naturally if an engine is suitable for creating electricity in a car, it would be suitable to provide electricity to buildings or tools. Besides a rotary engine used as a standalone generator, Hirose said the company is investigating the potential for complete cars to be used as emergency generators, since they're already mobile. Gasoline wouldn't have to be the only potential fuel, either. Hirose said Mazda is looking at possibly running the engine on liquified petroleum gas, or LPG. We asked if hydrogen was also being considered, since Mazda has a history of hydrogen-powered rotary prototypes, even some that could run on hydrogen or gasoline, but Hirose said that's not being looked at right now.
