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.

Mazda rotary engine returns in 2020 as an EV range-extender

It's really, truly, finally happening, folks. The rotary engine is coming back. And just as the many rumors, patents, and even a Mazda2 prototype suggested, it will return as a range extender for an electric car. The news comes from an official announcement from Mazda itself. We won't have long to wait, either, as the rotary-supported EV is slated to go on sale in 2020. It will be one of two electric vehicles available, the other being fully electric. Mazda also mentions that the rotary powertrain is small enough to fit "shared packaging layouts." It's a possibility that these two vehicles are variations on the same model, similar to the Hyundai Ioniq and Honda Clarity. Mazda further notes that the rotary engine will also be able to run on liquified petroleum gas, citing the engine's ability to handle gaseous fuels. This has us wondering if Mazda will offer compatibility with other fuels at some point. Hydrogen could be a good choice for California, and Mazda has had a number of hydrogen-powered rotary-engine vehicles in the past. Propane compatibility could be popular in other regions. Mazda didn't say anything else specific about the vehicle besides highlighting the rotary engine's high power output with a small package and smooth operation. It also mentioned that the range-extended car could be used as a source of electricity when the power grid is down. We're sure to learn more as we near the car's 2020 launch date. Related Video:

2017 Mazda MX-5 Miata RF Quick Spin | Elevate yourself

It's unusually hot in Western Washington; the early August sun beams through skies rendered hazy by fires a few hundred miles to the north. If you're not moving, it gets a bit oppressive, since there's just enough humidity to feel it and not enough wind to relieve it. Instead of huddling inside, window shades drawn, fan blowing hot air around impotently – this is how most Washingtonians, 75 percent of whom don't have A/C, handle the heat – we're taking our fan on the road. The best way to beat the heat, it turns out, is to climb into the forests. For this adventure in body temperature regulation, we've got a Mazda MX-5 RF, the Miata's semi-targa-topped variant, and a few hours of time. And the Cascade Mountain's foothills, thickly coated with Douglas firs and, higher up, subalpine firs soaking up as much sun as they can in the short growing season. I've lived near the foothills nearly all my life, but there's a lot of the Cascades I haven't explored. One area is Chinook Pass, a mountain road that crests at 5,430 feet. Looming almost 9,000 feet above it is Mount Rainier, so close you can almost touch it. Just about 100 feet below the summit is Tipsoo Lake, startlingly clear and sporting enough wildflowers to make The Sound of Music look like a movie about Rommel's North Africa campaign. But that's jumping ahead a bit. Between me and the summit is about 90 minutes of driving, through the suburbs and into the Enumclaw Plateau, and then along the chalky White River and up into the mountains. Plenty of time to focus on nothing but the surroundings, and the quality of the cooling action provided by the little Mazda. A quick word about the car, and my own biases – I love Miatas, but I have a complicated relationship with the latest MX-5, having owned a much more visceral (and much slower) first-gen car for about six years. On paper, it's this perfect modern interpretation of the original. It's light, it's a momentum machine, the steering's just a tad overboosted, and it has a playful amount of body roll while maintaining a healthy amount of mechanical grip. It looks aggressive enough, too, a major complaint of many folks about the last-gen car's Joker smile. The interior is largely brilliant, amazingly simple and interesting for such a lithe car. And yet, I have never found the new car to be as charismatic as my old Miata, with all its flaws. This puts me in the minority; most MX-5 fanatics find the ND to be a great compromise.
