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.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

Mazda won't build new Mazdaspeed3 or 6 based on current models

It's sad news but not entirely unexpected: According to a Motoring interview, Mazda doesn't intend to build high-performance versions of the latest Mazda3 and Mazda6. Instead, it will wait for the next generations of those cars to arrive before applying the Mazdaspeed treatment. When the future performance models do eventually arrive, expect them to take a step upmarket compared to the last ones. In the meantime, the Japanese brand will focus its engineering resources on the next-generation Skyactiv engine family, according to Mazda's North American operations president and CEO Masahiro Moro. "Our research and development department is 100 percent focused on delivering Skyactiv generation two and if we don't have this we don't have any other derivatives," Moro told Motoring. Once the new engines arrive around 2017, Mazda's engineers can start to develop performance versions. "MPS or performance model or a sort of iconic model of the future will be a little bit later at this stage," Moro said. Moro is already thinking about the direction for the future performance vehicles. He calls the previous Mazdaspeed3 "childish" and thinks it's time to go a different way. "Mazda brand has become more mature, more upscale, more sophisticated, and we have a new transition of the brand to relate that direction," he said. Rumors last year suggested that Mazda might introduce a new Mazdaspeed3 (speculative rendering above) as a concept at the 2015 Frankfurt Motor Show. It would have reportedly used the CX-9's 2.5-liter turbocharged four-cylinder tuned to 295 horsepower and an all-wheel-drive powertrain. The vehicle never appeared, though. The current Mazda3 and Mazda6 arrived in 2014, so a new generation of each wouldn't arrive until around 2020. That would put Mazdaspeed derivatives at 2021 or later. In short, it will be a while. For customers that have the Driving Matters attitude now, Mazda still offers the award-winning MX-5 Miata as a convertible and soon with an impressive folding hardtop. Plus, Fiat will sell its own versions of the car with 160 hp. We wouldn't mind if Mazda turned up the heat a little by introducing something like the Racing concept from last year's Tokyo Auto Salon, though. Related Video:
