Mazda to use rotary engine as a range-extender with its first electric vehicle

There's more news from Mazda at the Tokyo Motor Show, where the brand made a big splash, including new developments in its never-ending rotary engine saga. First, Mazda execs confirmed that the Japanese automaker will bring back the rotary engine as a range-extender and battery juicer for its first electric vehicle in 2019. But secondly, the company won't have a rotary-powered successor to its RX-7 and RX-8 sportscars in time for the company's centennial anniversary in 2020. Autoblog previously confirmed that Mazda is planning to have an EV in 2019 that will be available in both pure electric and range-extending versions. Now, the Australian website Motoring reports that the global EV will feature a powertrain similar to the experimental Japan-only Mazda2 (Demio) EV, which used a single-rotor engine as a generator to power the battery pack and increase its driving range. The publication says Mazda plans to release a series of plug-in hybrids based on existing models around 2020, then a pure electric car co-developed with Toyota and Denso in 2021 as part of the EV Common Architecture Spirit Company joint venture. A Mazda spokesman tells Autoblog the company couldn't confirm any details about future products. Meanwhile, enthusiasts shouldn't wait for a rotary-based production version of Mazda's RX-Vision concept from 2015. Motoring cites two executives who explain that the company simply lacks the capital necessary to invest in developing the new model in time for its 2020 centennial. Mazda debuted its rotary engine 50 years ago in the Cosmo Sport in part as a way to stand out from its larger Japanese competitors. The engine, which uses a spinning three-tipped rotor in place of pistons, is smaller and lighter than conventional piston engines, with a greater power-to-weight ratio and quieter, smoother operation. But it delivers less fuel economy and higher emissions — two weaknesses that could be improved via a stop-start system Mazda has developed, based on a pair of U.S. patents. The company has also been hard at work developing its next-generation Skyactiv-X engine, which uses highly precise combustion ignition technology to deliver significant gains in fuel economy and power.Related Video:

Mazda's new turbo four fits in both the 6 and the 3

Despite the size differences, the Mazda CX-9 shares a lot with its smaller car-based siblings, the Mazda6 and Mazda3. That could allow Mazda to slot its full-sizer's new 2.5-liter, turbocharged four-cylinder engine under the hood of its smaller offerings. Pardon us while we do a happy dance. "[The 2.5-liter turbo] fits in a lot of our cars, and where we're actually going to put it is another question," Mazda North America vehicle development engineer Dave Coleman told Australia's Car Advice. Coleman specified that the turbocharged engine will fit in all the same applications that can accommodate the company's 2.5-liter gas and diesel engines. "Basically, that big space we used for the bundle of snakes exhaust manifold, the turbo is in that space too. They're all packaged to occupy the same space. It's exactly the same clearance as the exhaust manifold of the other engines." This kind of logic – if Engine A is the same size as Engine B, then both should fit in Car C – is what's lead us to imagine a turbocharged Mazda6 since the new engine was announced. In short, it's great news. Mazda's 2.5-liter turbo is a hell of an engine in the CX-9, and it's hard to imagine it'd be worse in a lighter vehicle. But just because it works from an engineering standpoint doesn't mean it's going to happen. At least, not soon. "It fits. I'm not a product planner so I don't get to make that call," Coleman told Car Advice. "It's up to the product planners to decide what they're going to put it in." The most obvious application for a turbocharged engine in the 3 or 6 is as a reborn Mazdaspeed model. But don't get too excited – Coleman said Mazda hasn't even gotten as far as building an engineering prototype with this engine. We're still firmly at the theoretical stage. And that's bad news, because it gels with what we've been reporting – that Mazda will wait a generation for future Mazdaspeed models. We just stopped doing our happy dance. Related Video:

Mazda Furai concept designer talks about his car's passing

Last week, there was mourning at the Autoblog offices as word trickled in that the Mazda Furai concept - one of the coolest, best-looking showcars to grace an auto show stage since the wild and crazy 1960s -had been killed. It was killed on the track with the folks from Top Gear in attendance. We're sure the gods of driving would have wanted it to die on a circuit, but that doesn't make its fiery passing any easier to deal with.
The Furai is the rare concept car that had a lasting appeal with enthusiasts, partly because it was a real, functioning racecar, complete with a wacky three-rotor Wankel engine and cutting-edge Nagare design. Now that it's gone, though, Road & Track's Mallory McMorrow, who was an intern at Mazda Design when the Furai was being styled in 2007, has published an interview with one of the men who penned the Mazda showcar's striking exterior, Carlos Salaff. It's a great piece on the emotional connection between a designer and his creation, and one you should take the time to read. Click on over to R&T for the full story.
