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.

Recharge Wrap-up: Mazda, Subaru and Toyota PHEV, Nomadic Power grant

The next generation of the Toyota Prius Plug-in Hybrid looks to be important for Mazda and Subaru as well. Toyota will likely need to sell more of the new plug-in hybrid to meet stricter ZEV standards in California. That means it will get more extra electric range, as customers have been asking for. Subaru and Mazda will also have to adhere to the California standards beginning in 2018. Those two smaller automakers will likely license a plug-in hybrid powertrain from Toyota in order to fulfill compliance. Read more at Green Car Reports. Tesla is partnering with Dalhousie University to improve battery technology. Tesla signed a five-year research agreement with Dalhousie's Jeff Dahn, a lithium-ion battery researcher. Dahn and the 25 researchers in his lab will work with Tesla's Director of Battery Technology, Kurt Kelty, to increase capacity through improved materials. The collaboration could be important both for Tesla's automotive and stationary batteries. "Our research group's goal is to increase the energy density and lifetime of Li-ion batteries, so we can drive down costs in automotive and grid energy storage applications," says Dahn.

Nomadic Power's mobile batteries, called Nomads, have incorporated photovoltaic systems and can be used to extend the electric driving range of a plug-in vehicle, or to provide backup power to a home. The Nomads use an intelligent energy management system to learn and predict user behavior and manage the solar system based on weather forecasts. "We see a strong future in electric-powered mobility and an increasing use of renewable energy, photovoltaic power in particular," says Nomadic Power CEO Dr. Manfred Baumgaertner. "Our mobile batteries have great potential in these markets that recently got a significant shot in the arm by Tesla's announcements." Read more from Nomadic Power, and at Green Car Congress.

2014 Mazda Skyactiv Prototype looks ready for Daytona

With less than two weeks before the Mazda Skyactiv Prototype makes its race debut at the 2014 Rolex 24 at Daytona, the Japanese Zoom-Zoom brand brought its diesel-powered racer to the floor of the 2014 Detroit Auto Show.
The red prototype marks Mazda's return to prototype racing, and will campaign the inaugural Tudor United SportsCar Championship using a 2.2-liter, SkyActiv-D diesel engine. With 451 horsepower on tap and 580 pound-feet of torque, the racer should stand up well against a field of gas-powered competitors.
Should the Skyactiv win Daytona, it'll be a coup for Mazda. The racer is running an engine with over 50 percent of its parts drawn from the oft-delayed production Skyactiv-D. Head up top for our full gallery of images of the new Skyactiv Prototype. The 2014 Rolex 24 will be run from January 25 to 26.
