Mazda2 with extended-range hybrid rotary tech shown

Every story dealing with a new rotary engine from Mazda lands in a different place on the matrix of possibilities between "Coming soon!" and "Never gonna happen!" In 2011 it was speculated that the rotary engineering program would be shut down with the demise of the RX-8, in 2012 the program was still alive and taking lessons from the SkyActiv engines, in August 2013 a Mazda insider said a rotary engine called 16X would be here in two years, in November the CEO said the only way we'd ever get a new rotary is if Mazda could sell 100,000 of them per year. Meaning that, for the moment, you can forget about it.
And yet, last month Mazda was putting journalists in a Mazda2 RE Range Extender, an electric car using a 0.33-liter rotary to power its lithium-ion batteries when the charge runs down. With a 75-kilowatt, 100-horsepower electric motor turning the front wheels, the Wankel generator and its 2.6-gallon gas tank living under the trunk double the range of the electric-only Mazda2 to 250 miles.
There's been talk of using a rotary to assist an alt-fuel vehicle for at least seven years, with Mazda pairing an electric motor with a rotary that ran on gas and hydrogen in a Mazda5 in 2007. Since then, almost all of those stories debating its return or demise also spoke of the oddball motor's advantages, such as compact size and ability to run on various fuels, as an aid in an unconventional powertrain.

Mazda concept probably previews the next Mazda3 at the Tokyo show

This year's Tokyo Motor Show is shaping up to be an interesting one, with a Nismo Leaf, Mitsubishi e-Evolution concept, and a pair of interesting Toyota concepts already lined up. Now Mazda is joining with its own big reveal of two concepts. One is a design concept that will give us an idea of where the company is heading, and another is all but guaranteed to be our first look at the new Mazda3. There are a few reasons we say that one of these concepts has to be the next Mazda3. One is the fact that Mazda says it's a concept planned for production. The company also describes it as "a compact hatchback that fuses next-generation technology and design," and it uses the new Skyactiv-X spark-controlled compression ignition engine and "Skyactiv-Vehicle Architecture." Plus, just looking at the teasers, the design is a clear evolution of the current Mazda3 hatchback. It looks as though the hood and roofline curve a bit more, and some of the sharp creases of the current car have been smoothed out. The other concept Mazda is bringing to the Tokyo Motor Show seems to be just that, a concept. Mazda says it's just a design concept meant to exhibit how other Mazdas will look. Apparently it's a continuation of the company's current "Kodo" design language. Based on the teaser image, the car appears to be a sedan and consists mainly of clean, elegant curves, with hardly a crease anywhere except the edge of the trunk. The elegant lines are reminiscent of the RX-Vision concept, just with a couple extra doors and a different color. Mazda will have a couple of other new vehicles on display in Tokyo as well. The company will show the Japan-only CX-8 three-row crossover and a special-edition Roadster (Miata) Red Top edition. We presume it's a Miata with a red soft top. Stay tuned for more details from the full reveal. Related Video:

Mazda could electrify the next Miata, is trying to figure out how

The next Mazda Miata is at the embryonic stage of development. The men and women in charge of the project are debating whether to electrify the roadster, or if it's better to keep it true to its roots. The Miata is not a high-volume model in any market, so it doesn't need a plug to help Mazda comply with looming emissions regulations. The company explained it's not a matter of compliance; it's about how the definition of a sports car and the expectations of motorists could change in the 2020s. "The preferences of people who enjoy driving sports cars might be changing, so we need to think about what direction society is going in. We want to look at the best powertrain to keep the vehicle lightweight, but because of the diversifying requirements and preferences, we need to explore various options," Ikuo Maeda, Mazda's global design director, in an interview with Autocar. Adding any degree of electrification to the Miata beyond a relatively basic mild-hybrid system is easier said than done. An unusually low weight and a compact footprint defined the original model introduced in 1989, and these attributes continue to characterize the fourth-generation car (pictured) sold in 2019. Electrification requires batteries, batteries add weight and require space, and Mazda doesn't want to end up with a 3,000-pound Miata, or one that's the size of a Mercedes-Benz S-Class Convertible. Keeping its chassis balanced is a delicate task, too. Overcoming this challenge is not impossible, however, and batteries are expected to become lighter and smaller during the 2020s. The next-generation Miata isn't expected out until the middle of the 2020s, so Mazda has time to figure out whether it should go hybrid, arrive as an electric car, or carry on with a rev-happy, naturally-aspirated four-cylinder engine. Maeda stressed a final decision on the matter hasn't been made yet. "I don't have the answer right now, but we need to make a vehicle that people can own without worrying that they are not being eco-friendly," he concluded.
