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.

Will the Mazda2 be offered as a PHEV with a rotary engine range extender?

Every few months, it seems a rumor crops up about plans from Mazda to revive the rotary engine. Last November, its CEO said the only way another one could happen is if the project was profitable, and then a month later the automaker showed off the Mazda2 RE Range Extender with a 330cc Wankel engine mounted in the rear. Now, Australian auto site Motoring reports that the PHEV may actually make production in the next-gen Mazda2 sometime after it's initial launch.
Martin Benders, managing director of Mazda in Australia, spoke to Motoring about the company's future with hybrids and basically reiterated what the CEO said last year. The Japanese automaker only plans to offer electrified powertrains in places where they can sell in sufficient numbers to be profitable, like Japan.
Mazda has been playing with the rotary range-extender idea for years. In the RE prototype, the engine was exclusively used to charge the lithium-ion batteries when they were running low, and a 100-horsepower electric motor provided all of the propulsion. It gave the little hatch an estimated range of about 250 miles. The company reportedly took inspiration from its Skyactiv engines to make the Wankel have lower friction and a lighter weight.

White House clears way for NHTSA to mandate vehicle black boxes

At present, over 90 percent of all new vehicles sold in the United States today are equipped with event data recorders, more commonly known as black boxes. If the National Highway Traffic Safety Administration gets its way, that already high figure will swell to a full 100 percent in short order.
Such automotive black boxes have been in existence since the 1990s, and all current Ford, General Motors, Mazda and Toyota vehicles are so equipped. NHTSA has been attempting to make these data recorders mandatory for automakers, and according to The Detroit News, the White House Office of Management Budget has just finished reviewing the proposal, clearing the way. Now NHTSA is expected to draft new legislation to make the boxes a requirement.
One problem with current black boxes is that there's no set of standards for automakers to follow when creating what bits of data are recorded, and for how long or in what format it is stored. In other words, one automaker's box is probably not compatible with its competitors.
