Sorry, rotary fans, Mazda's RX Vision probably won't happen

Mazda is doing a lot of things the right way in this age of beige-ness. It just crammed a turbocharged inline-four into the improved CX-9, a bold move unto itself, and one that should also be heartening for Mazdaspeed fans. Wouldn't that engine make for a swell Mazdaspeed3 or Mazdaspeed6? There's a reasonable ray of hope there, but not necessarily a guarantee. The RX Vision, though, is a pipe dream. Mazda is smart to keep the rotary dream alive. It's smart to keep developing it in back rooms and to keep the idea on the public's mind. Credit where credit's due: Mazda has solved some of the stickiest issues the rotary engine has, through savvy engineering and perseverance. We've seen promising patent filings for the Skyactiv-R engine, which is supposed to be found in the RX Vision concept. Mazda uses every opportunity to remind us that development is continuing and that the company would love to bring a rotary-powered sportscar to production. I believe it. But the RX Vision is just a design study. And there are some harsh realities about rotary engine emissions and fuel economy standards that are difficult for modern piston engines to achieve without expensive componentry. Emissions and fuel economy are both bugbears of the rotary, in case you've forgotten. And that explains Mazda's interest in running rotaries on hydrogen, but down that road lie infrastructure challenges as daunting as making a gasoline-powered rotary burn as clean as one of Mazda's Skyactiv piston engines. All this is meant to put Mazda's recent comments to Top Gear in context. Mazda's design director, Kevin Rice, spoke to TG at the Concorso d'Eleganza Villa D'Este, and was waving Mazda's rotary flag quite enthusiastically. "In the back rooms at Mazda, we're still developing it," Rice said, "and when the world's ready to buy another rotary, we'll be ready to provide it." I'd like that to be a comforting statement, but given the realities of fuel economy and emissions regulations and Mazda's position in the market, it seems like a hollow platitude. "When the world's ready" is just another way of saying "when we solve the fundamental issues with this engine layout, and there's an unambiguous market study that shows we can build these cars and make a profit, we'll consider it." That seems like a lot of "ifs". Perhaps Mazda does have a clean-burning, efficient, cheap-to-produce rotary running on an engine dyno in Hiroshima, and it's prepping an RX-9 for the next auto show.

RingBanana Miata breaks 9-min Nurburgring barrier

The RingBanana is a cheap Mazda MX-5 Miata on a screaming mission: to lap the Nurburgring in under nine minutes. And let us emphasize the word "cheap." The team wanted the least expensive Miata they could find that still ran, and then wanted to spend the least amount of money possible in order to hit their target mark. We don't know how much they spent on the Ringbanana, but they were so indiscriminate about the purchase that they don't know what year the car is. They only know that it's got 90 horsepower, green springs, Fulda tires, and "it's completely crap." After setting a base lap of 9:21.8 the guys behind the project figured they'd have a fair bit of work. Turns out a new set of Kumho V70A semi-slick, road-legal race tires paired with Gabriel Pirana's driving is all they needed. With just that mod Pirana set a lap time of 8:59.9, and that was while having to deal with one spot of slow traffic that was getting around a stricken car. According to Wikipedia, this puts them between a 2010 Range Rover Sport Supercharged and a 2007 Chevrolet Cobalt SS. Even though the team achieved its goal on its first attempt, the Ringbanana game isn't over – there's probably a suspension mod in the near future while the guys figure out just how quickly they can go. The video above does a good job of showing just how fun it can be driving a slow car fast.

Next-gen Mazda6 reportedly getting RWD, straight-six it shares with Toyota

Last June, Japan's Best Car magazine laid out what we considered a whopper series of rumors about future Mazda developments. The mag said it had been speaking to a Toyota source on an unrelated matter, and found out that Mazda's work on a straight-six Skyactiv engine was predicated on that engine's use in Toyota Group vehicles, including Lexus models. Car and Driver has apparently consulted its own sources, and in a new report utters many of the same pronouncements as Best Car. The next-generation Mazda6, due around 2022, will molt out of its transverse engines on a front-driver platform, and be the first home for the longitudinally-mounted straight-six on the automaker's new rear-wheel drive "Large Architecture."  The gas-powered Skyactiv-X six-cylinder, a shade under 3 liters of displacement, will get help from a 48-volt hybrid system, and top output could hit 350 horsepower. A second straight-six will come in an oil-burning Skyactiv-D flavor, and PHEVs are certain to eventually factor into the equations. The sheetmetal around the bodywork will draw inspiration from the four-door Mazda Vision Coupe concept that debuted at the 2017 Tokyo Motor Show. Describing a scenario we can only cross our fingers for, C/D writes "there's a chance Mazda will mimic Lexus and put inline-six into both four- and two-door bodies," grabbing another unused concept as a design guide for the latter, the two-door RX Vision concept from the 2015 Tokyo Motor Show. C/D suspects the increasing cooperation between Mazda and Toyota will not only pay the bills for Mazda's sports sedan, but compel the Large Architecture to take a couple of side jobs in Toyota City. C/D writes, "Toyota may adopt the six-cylinder Skyactiv-X for the next-generation Lexus IS and RC." According to the recently leaked dealer report, the next-gen IS could be with us in 2021 as a 2022MY offering. Betting money seems to be on the sedan sticking with Toyota's TNGA platform and Lexus engines until a brand new model shows around 2026, though.
