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.

Our Mazda MX-5 Miata has the best engine bay in the business

One of the things that's really disappointing about modern cars is how they all hide their technology under a proverbial bushel. You pop the hood, and nine times out of 10, you're faced with some amount of black plastic hiding the functional bits. On some cars the plastic covers the bare minimum to have a "presentable" engine. Others have every tank, hose, wire and screw buried under a layer of smooth plastic. Few exemplify this practice better than engine bay of the current Lexus LS 460, seen below. If Lexus was this embarrassed about its engine, maybe it should have simply bolted the hood shut. However, like with weight gain and power creep, our fourth-generation Mazda MX-5 Miata bucks the plastic trend. Lift the aluminum hood of the little roadster, and you travel back in time more than a decade. (See the gallery up top.) Only one bit of decorative plastic is in sight, and it proclaims the car's Skyactiv technology and hides some of the wires leading to the ignition coils. Otherwise, nothing else is obscured. The shock tower braces, manifolds, battery terminals, the whole shebang is all right there for you to see. What's particularly amazing is that it all looks good. Even in some cars that eschew plastic covers, it's no guarantee of an attractive engine bay. We just had a new Honda Civic Sport hatchback (seen immediately above), and while it doesn't sport a plastic engine cover, you can see from the photo that it's not particularly attractive with tubes and cables snaking every which way. But in the Miata, the hoses and wires are kept to a minimum, and the ones that are there are arranged in a way that isn't haphazard or tangled. Then, in the middle, there's the clean, simple aluminum cam cover as the gleaming centerpiece, similar to those of the first- and second-generation cars. As the owner of a '99 Miata, this detail in particular gives me the warm fuzzies. The fully exposed engine bay fits with the Miata's personality. The car is very straightforward, it features just the absolute minimum of style and comfort additions, and is highly accessible. I would say the Miata's engine bay is the window to its soul, if driving it didn't offer a clearer picture. Related Video:

Takata airbag recall spreads to China with 42k Mazda sedans

The scope of the problem with the faulty airbag inflators from Takata continues to broaden and is now reaching China, as well. Mazda is recalling 42,732 Mazda6 units there, produced by its local joint venture partner China FAW Car Company, to replace the front passenger airbags. It comes as part of Mazda's recall of nearly 160,000 vehicles worldwide, including about 34,600 in the US, according to Reuters.
This is the same problem that caused seven automakers in the US to recall an estimated 2.1 million vehicles in late June. The airbag inflators can potentially explode instead of deploying the airbag, which hampers the bag's inflation. In some cases occupants are also hit by the metal shrapnel, which can cause further injuries. In the US, Mazda is repairing the 2003-2007 Mazda6 (pictured above), 2006-2007 Mazdaspeed6, 2004 MPV and 2004-2008 RX-8 originally sold in or currently registered in Florida, Puerto Rico, and Hawaii.
This is hardly the first instance of this issue. Since 2001, there have been 20 recalls tied to the exploding airbags supplied by Takata. The problem is possibly linked to the propellant in the inflators, but there's no conclusive evidence of that yet. Most of the automakers in the US limited the most recent recalls only to a few humid states because moisture potentially exacerbated the problem.
