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:

Next Mazda MX-5 Miata to weigh a ton(ne), literally

Looking at recent spy shots of the fourth-generation Mazda Miata, it's obvious this sporty little roadster will grow in size compared to the current model, but it's also going on a diet. At the Tokyo Motor Show, Auto Motor und Sport sat down with Mazda executive Kiyoshi Fujiwara, who gave a little more insight into the Miata's redesign.
Fujiwara said that they're aiming for a curb weight of a tonne (metric ton), which is 1,000 kilograms or right around 2,200 pounds, for the next-generation Miata. This would make the roadster at least 300 pounds lighter than the current NC Miata, but still about 200 pounds heavier than the original NA.
There is no indication as to how Mazda will go about removing that much weight from the bigger car, but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight. Improving the power-to-weight ratio appears to be a key goal of the Mazda team, so we also wouldn't be surprised to see a more powerful engine underneath the longer hood.

Mazda RX-Vision Concept revives the rotary

Mazda continues fighting to keep the rotary alive, and with the RX-Vision concept at the 2015 Tokyo Motor Show, the company unveils its dream for the engine's revival in a curvaceous sports coupe. Before any fans burst with excitement at the prospect, Mazda only "hopes" to have this gorgeous shape available in showrooms someday, for now. The RX-Vision starts with the classic elements of a front-engine, rear-wheel drive sports coupe by combining a long, low hood, short rear deck, and a passenger compartment way at the back. From there, Mazda's stylists add the swooping touches of the brand's Kodo design language. The result looks thoroughly modern and still subtly evokes generations of the RX-7 in the sculpted fenders and flowing roofline. Under that shapely hood hides Mazda's next-generation rotary, which the company has dubbed the Skyactiv-R. Unfortunately, details about it are quite scarce at the moment, including the displacement or even the number of rotors the engine uses. Still, Mazda is abundantly clear that development of the mill is very much moving forward. Mazda's designers opt for a retro flair inside with the deeply dished steering wheel and gauges in three pods. The rest is simple and elegant with a minimalist, metal gearshift rising from the center console and leather straps for door pulls. Finishing things off is a clean mix of red and black upholstery with a little carbon fiber for contrast. Expect live shots from Tokyo soon to show how the RX-Vision looks under the lights.

The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967.
