Mazda's rotary-engine range extender could serve as an emergency generator

GENEVA — Mazda has some pretty exciting powertrain technology in the works, particularly its Skyactiv-X spark-controlled compression-ignition engine, but also the upcoming range-extended electric vehicle with a rotary engine. It offers the possibility of electric transportation with a distinctly Mazda way of getting electricity from gas when charging isn't an option. But we learned that Mazda has some other ideas for the rotary range-extender beyond transportation, and even beyond gasoline. In talking with Ichiro Hirose, Maza's managing executive officer for powertrain and vehicle development, product planning and cost innovation, we learned that the company is exploring the powertrain's potential as an emergency generator. Naturally if an engine is suitable for creating electricity in a car, it would be suitable to provide electricity to buildings or tools. Besides a rotary engine used as a standalone generator, Hirose said the company is investigating the potential for complete cars to be used as emergency generators, since they're already mobile. Gasoline wouldn't have to be the only potential fuel, either. Hirose said Mazda is looking at possibly running the engine on liquified petroleum gas, or LPG. We asked if hydrogen was also being considered, since Mazda has a history of hydrogen-powered rotary prototypes, even some that could run on hydrogen or gasoline, but Hirose said that's not being looked at right now.

2019 Subaru Ascent vs. 2018 Mazda CX-9: Driving two class leaders side-by-side

As the de facto replacement for the family sedan, we expect a lot out of modern crossovers. They need to excel at family-hauling duties while delivering reasonable performance and fuel economy. They have to offer all-wheel drive and the latest safety technology. They ought to be ruggedly handsome, and they can't be so prohibitively expensive that the families they are targeting can't afford them. It's a tall order, and some automakers have hit closer to the proverbial bullseye than others. By some stroke of luck, we managed to snag a 2018 Mazda CX-9 Grand Touring as our chariot to take the four-hour drive from Seattle to McMinnville, Ore., where we got our first drive of the 2019 Subaru Ascent. As one of our favorite vehicles in this class, the CX-9 would serve as a good comparison to the Ascent. And, on paper, the similarities are abundant: Both come from automakers with a clear, go-your-own-way approach to vehicle engineering, are powered by turbocharged four-cylinder engines, and offer three rows of seating in a relatively compact package. Put simply, we expect the Ascent and CX-9 to be cross-shopped by a lot of new-car buyers looking for a new family car. What we found is that the CX-9 is the better choice for the buyer who values a sporty driving experience above all else, while the Ascent is probably better for families looking for a healthier dose of practicality. Either option will ably serve the suburban American family they are targeting, but the ways they go about that life of servitude are quite different. It's worth noting that pretty much every automaker in America is selling a vehicle in this class, which means there are a heck of a lot of vehicles from which to choose.

With that out of the way, let's break it down a bit more granularly. Styling: View 36 Photos Looks-wise, we prefer the Mazda. A crossover is going to be generally box-shaped, but that doesn't mean it has to be boring. The CX-9's bodywork flows gracefully from nose to tail, with just the right amount of flashiness in the form of headlights that take the form of cat-like eyes, a five-point grille surrounded in chrome, and gently arcing bodyside lines. It all works to form what we think is the most attractive midsize crossover overall. We don't hate the Subaru Ascent's looks, but it's definitely more boring than the CX-9.

Mazda's rotary engine may live on as a range extender (UPDATE)

Update: We received a response from Mazda that confirmed plans for a 2019 electric car available in battery-only and range-extended models, but there was no comment on any other details. The text has been updated to reflect this. It may be time for rotary fans to start getting their hopes up a little for a return of the spinning triangle engine. Automotive News spoke with Mitsuo Hitomi, the man in charge of Mazda powertrains, who said there's a very good chance the next implementation of the rotary engine will be as an electric car range extender. The news source also suggests that such a vehicle could be just around the corner, since Akira Kyomen, Mazda's vehicle development program manager, confirmed to Automotive News that the company will have an EV out in 2019 in both pure electric and range-extended versions. We reached out to Mazda for more information, and a representative confirmed both the pure electric and range-extended models for 2019, but couldn't comment on anything else regarding those vehicles. Looking back, we have reason to believe that this really might happen. As far back as 2013, Mazda was working on a rotary-engine range-extended electric car in the form of the Mazda2 RE Range Extender. It had a total range of 250 miles, half of which came from its battery, the other half from a 330 cc rotary engine generator fueled by a 2.6-gallon gas tank. More recently, Mazda has also teased rotary power with the RX-Vision concept at the 2015 Tokyo Motor Show and another rumored rotary concept at this year's show, which could be the design concept teased recently. But most convincing is the patent we found from Mazda that described a range-extended electric car that would specifically use a rotary engine. The powertrain layout looks just like the one used in that Mazda2 concept. There's also the fact that, as we've previously pointed out, and as Hitomi mentioned to Automotive News, the rotary could be a good range-extender due to its compact size and smoothness. Of course it also isn't known for being the most efficient engine, but if it isn't required to provide all the forward propulsion, it could be made small enough that it's frugal, and the added space and weight savings would be important for making the vehicle more practical, adding more batteries, or simply keeping the car lighter. This news might not excite rotary die-hards who have been waiting for an RX-7 and RX-8 successor, but they shouldn't quite abandon hope yet.
