50 engineers kept the rotary alive at Mazda for 8 years

The Mazda RX-Vision concept is one of the standouts at this year's Tokyo Motor Show thanks to a drop-dead gorgeous design and a revival of the Wankel engine. The fact that the rotary is still in development at Mazda is thanks to a dedicated group of 50 engineers. According to Automotive News, their dream for the last eight years has been to bring this storied engine design back to the street. It won't be easy. Because of its design, the rotary suffers from poor fuel economy and high emissions. Making the challenge even harder, Mazda reportedly only gives them a small budget, but they continue to chip away at the problem. "These 50 engineers want to develop the rotary engine, therefore they joined Mazda," company research and development boss Kiyoshi Fujiwara told AN. "If I stop the rotary engine, probably they want to leave." For the Skyactiv-R under the RX-Vision's svelte hood, the team reportedly started from the 16X rotary project. Dating back to 2007, that 1.6-liter engine was supposed to improve torque and fuel economy thanks in part to direct injection. After additional development, insiders even suggested that the engineers might have finally solved the powerplant's issues. However, Mazda never put the mill into production, and the RX-8 remains the company's last Wankel-powered model to be offered in showrooms. "We have a dream that one day, this design with a rotary engine will achieve a level that customers will accept," CEO Masamichi Kogai said to AN. Mazda is quite clear that the RX-Vision might never go on sale without a suitable rotary. Although if it does see production, the coupe would likely use a stiffened version of the Miata's chassis, AN reports. Before anyone can place an order, these 50 determined engineers still have a lot of work ahead of them. Related Video:

The Miata is always the answer, but which one is the answer for you?

If you follow along with our long-term vehicles, you know that we had a 2016 Miata Club in the fleet. It's a Miata that had every sporty bit available installed, but there are other ways to spec out an MX-5. Just recently, we had the chance to sample the other end of the MX-5 spectrum, the Miata RF Grand Touring. While they're cut from the same sheetmetal, they're surprisingly different cars. So we thought we'd put together a little guide to help you figure out what bodystyle and trim level of Miata is right for you. How do you like the wind in your hair? If you're someone who loves soaking up the sun and having the wind blow through your hair, or lack thereof, there's no replacement for the soft-top Miata. The manual folding mechanism will get you out into the fresh air faster than virtually any other convertible, and it will go back up just as easily when the rain comes. Raising and lowering it is quick and easy, and can be done with one hand from the driver's seat. And with the top down, you'll be greeted by breeze from virtually every direction, and an airy, unencumbered feeling that only comes with a full convertible. However, if you prefer to keep your hair in place and just get some sun, the RF is the better choice. The retractable targa top still descends and reemerges quickly, taking just 13 seconds either way. Keeping the windows up with the targa stowed will allow in plenty of sun, but will keep wind to a minimum. But when the windows drop, you'll still get a healthy dose of airflow. It still doesn't feel as open as the soft top, though, since you'll be able to catch the fastback pillar out of the corner of your eye. But if you value protection over airflow, that won't be an issue. View 11 Photos Does your Miata need to be a daily driver and occasional road tripper? While many Miatas will be weekend toys, one of the appealing things about them is that they're reliable enough and have just enough cargo space that they can serve as an everyday vehicle. For people who want to use a Miata as a daily commuter, and even take it on road trips, we would recommend an RF with the Grand Touring trim, as seen above. Although it still isn't a quiet car in the grand scheme of things, the RF's solid top makes it more livable for highway stints both short and long. The Grand Touring trim comes recommended for these purposes for a couple of reasons. Foremost is the more forgiving suspension shared between it and the base-level Sport.

Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.
