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:

Mazda still has a team working on rotary engines

The flame still burns within Mazda to stage a rotary engine revival. Before you start getting excited, it's way too soon to start saving money for the fabled, next-gen RX-7 or RX-8. Still, company boss Masamichi Kogai confirmed to Autocar that the Japanese automaker has an engineering team dedicated to improving the Wankel. This development group has the hard task of trying to make the rotary stack up to modern internal combustion engines in terms of emissions and fuel-economy standards. Neither factor were ever exactly Wankel's strong suits. Kogai described them as working "very enthusiastically" to Autocar. The boss didn't discuss any future RX-vehicles or the size of the team, however, a report from last year indicated that there were 30 engineers in partnership with universities to update the engine's design. After problems keeping up with emissions and fuel economy, Mazda built it's last rotary for an RX-8 in June 2012. Since then, there have been intermittent rumors of a return. One possible solution was a design called the 16X that was supposed to offer more torque and better fuel economy. Another possibility was a small-displacement unit as a range-extender in an electric Mazda2. Rumors of a new RX-7 have been heard for years. In 2013, Kogai clearly said that it wasn't happening. When asked again last year, he reiterated the same point.

Mazda starts production of new MX-5 Miata in Japan

We often regard a new model as having arrived when its manufacturer reveals it for the first time. But you might argue that nothing is official until actual production gets underway. And that's just what's happened now with the new Mazda MX-5. The fourth-generation Miata was unveiled a few months ago, and now the first examples have begun to roll off the assembly line at Mazda's Ujina plant in Hiroshima. The first ones are set to stay in Japan, where the new roadster is being introduced initially. Deliveries are set to launch in June. After that, we can expect the new MX-5 to proliferate to markets around the world, including our own. To date Mazda has sold more than 950,000 of its little roadsters, making it the best-selling two-seat sports car in the world. It shouldn't be long, then, before the new model tips it past the million-unit mark. 2015/03/05 Mazda Starts Production of All-new Mazda MX-5 HIROSHIMA, Japan-Mazda Motor Corporation today began production of the all-new Mazda MX-5 two-seater lightweight sports car (known as Mazda Roadster in Japan) at Ujina Plant No.1 in Hiroshima. The first models produced are destined for the Japanese market. Sales of the all-new MX-5 will begin in Japan around June this year and interested buyers can make an appointment for pre-sale discussions through a dedicated website from noon on Friday, March 20. Following sales start in Japan, the MX-5 will be progressively rolled out to overseas markets. The MX-5 is an iconic model representing Mazda's vehicle engineering philosophy: the pursuit of driving pleasure. With production exceeding 950,000 units as of the end of January 2015, the MX-5 continues to hold the Guinness World Record for the world's best-selling two-seater sports car. In order to respond to ever increasing demands for safety features and environmental performance while maintaining the element of fun that has always defined the model, development of the fourth generation MX-5 was carried out under the motto "innovate in order to preserve". In addition to incorporating SKYACTIV TECHNOLOGY and KODO-Soul of Motion design, development focused on enhancing the senses and sensations through which people enjoy cars. Moving forward, Mazda will continue to enrich the lives of its customers through a variety of touch points including the production of high-quality vehicles, and become a brand that maintains a special bond with its customers.
