Mazda officially hints MX-30 could get a rotary range-extender

Mazda recently penned a paean to itself celebrating 100 years in business. This, naturally, meant the document also served as a love letter to the rotary engine, since, "The joy of driving, lightweight design and the rotary engine [are] three elements that define Mazda’s DNA." One of those elements has been AWOL for eight years, since the end of RX-8 production. After years of rumor feverish enough to impress Slenderman, two years ago Mazda announced it was prepping a rotary range-extender engine for a model to debut in 2020. Here we are in the anticipated year, and we still don't know anything else about that vehicle — or perhaps we do. When Mazda debuted the MX-30 battery-electric crossover in Tokyo last year, it bore an e-SkyActive powertrain with a 35.5-kWh battery sending current to an e-motor on the front axle producing 141 horsepower and 195 pound-feet of torque. With a range of around 130 miles on the European cycle, even though the crossover was meant for markets like Europe and Japan, almost everyone chimed, "This would be perfect for that range-extender engine." The automaker has hinted at that very thing for its centenary celebration. In a paragraph touching on alt-fuel RX-7 variants, the Mazda press department wrote, "Later, the company developed a prototype Mazda2 EV with a small single-rotor engine used as a range extender. A similar system could find its way onto the Mazda MX-30, a brand new battery electric crossover SUV arriving at dealerships this year." The word "could" didn't make the leap from the printed page into the video translation of the presser, a Mazda video on "The Dream Engine" ending with footage of the MX-30 rolling under the caption, "Mazda MX-30 with rotary range extender." When asked, Mazda's head of R&D in Europe explained the battery size and resultant range with wheel-to-well considerations that factored energy input and emissions output from making the battery to exchanging the battery after 100,000 miles of driving. Since the carmaker doesn't deem the pure-electric MX-30 suited to the U.S., the question bubbling beneath the latest news is whether this revised model with more range could make it here. Given a suitably sized fuel tank that could power the little people mover beyond 150 miles on U.S. roads, and a fair price, we suspect there'd be a great deal of interest. Now, Mazda, about that rotary-powered RX-7 ... Related Video:    

Next-gen Mazda MX-5 Miata mule spied 'Ring testing

Fans of simple, lightweight motoring, rejoice - we now have images of the next-generation Mazda MX-5 Miata undergoing testing at der Nürburgring Nordschleife. Now, to be fair, this isn't some lightly camouflaged example that will give us a great peak of what the next Miata, which will also become the next Alfa Romeo Spider, will look like. This is a mule, with the new bits hidden under a current Miata's body. That doesn't mean there aren't a few scraps of valuable information here, though.
According to our flock of camera-toting spies at the Nürburgring, the next Miata is likely to grow a bit, as new models are wont to do. In particular, it will be longer and wider, and the wheelbase is likely going to be stretched, based on the shape of the wheel wells and doors. Both of those factors will add more space in the cabin.
Those are the big indications provided by these photos, but while the MX-5 might be growing, it's a safe bet based on these images that it, and the (likely pricier) Alfa, will retain the classic, long-hood, short-deck styling that so typifies rear-drive roadsters.

Mazda says Skyactiv-X will come to the U.S, but not when

Mazda executives say the new 2.0-liter Skyactiv-X powerplant will still take some time to arrive to the North American market. The Skyactiv-X is a high-compression gasoline engine, and its 16:1 compression ratio is comparable to that of a diesel engine. "We have a lot of technology. And we are introducing each technology in each region when the time is right," said Mazda North America CEO Masahiro Moro at the SAE International WCX Conference, according to Automotive News. Moro stated that while the Skyactiv-X can indeed pass EPA emissions regulations, it's not in the immediate pipeline for U.S-bound Mazdas; the slightly less hardcore Skyactiv-G will be amended first. The launch-spec 2.5-liter Skyactiv-G engine in the new Mazda 3 will reportedly be supplemented by a 2.0-liter Skyactiv-G, which also has a bold compression ratio: according to Mazda, its ratio of 14:1 is the highest of any production gasoline engine. However, Moro didn't state the exact timeline for that Skyactiv-G's arrival, either. The compression ratio of the 2.5-liter "big block" available now is 13:1. In the 2019 model-year Miata roadster, the 2.0-liter Skyactiv-G makes 181 horsepower, and an earlier Slovakian Euro-spec leak mentioned the 2.0-liter 3's power figure at 164hp. The bottom line is thermal efficiency through being able to extract more energy out of gasoline, and moving from G to X would improve fuel economy by 20-30 percent while giving more power. If the Slovakian specifications are to be believed, the Skyactiv-X would make 178h p and 164 lb-ft in the Mazda3.
