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.

2016 Mazda MX-5 Miata won't get power folding hardtop

Following the reveal of the 2016 Mazda MX-5 Miata, more and more details (and rumors - oh, the rumors) are coming out regarding exactly what's in store when the car finally goes on sale. Our own Chris Paukert had plenty to say about the exterior and interior, and we've now seen the first photo of the engine. But a new report from Automobile sheds even more light on the 2016 Miata - specifically, that the power folding hardtop model won't be available, at least initially.
Automobile reports that the 2016 MX-5 will only be offered with a cloth top, and an insider confirmed that the mechanism is light and accessible enough that it can be raised and lowered with one hand from inside the car. Mazda officials would not comment on the availability of a hardtop in the coming years.
That said, a hardtop Miata isn't out of the question. There will likely be some sort of fixed roof available - even as a one-piece, lift-off accessory - if only for club racing. Also, remember that the current NC Miata's hardtop is the only one on the market that doesn't take up any additional trunk space, so it's an attractive proposition for buyers. Currently, the power hardtop is only offered on the Club and Grand Touring MX-5 Miata trims.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
