Mazda rotary engine returning in 2019 as EV range extender, exec says

It seems that a range-extended Mazda electric car with a rotary engine is for real, and coming sooner than expected. An automotive news outlet from the Netherlands called AutoRAI spoke with Mazda's European vice president for sales and customer service. He told the outlet that Mazda has an electric car coming In 2019, and it will be available with a rotary engine as a generator. Among the details about this car and its powertrain, he said it would be similar in size to the Mazda3, and it might even be a crossover. It will also be based on Mazda's upcoming modular small car platform. The rotary engine will only generate electricity and will only have one rotor. Not only that, it will be mounted horizontally. This is particularly unusual as every rotary Mazda has had the engine mounted upright. We've reached out to Mazda representatives in the U.S. and Europe. An American representative couldn't comment on what type of range-extender options may be coming in the future. We say this specifically because Mazda has confirmed previously that an EV with an available range extender is coming in 2019. We have not heard back from a European representative at the time of publishing. Despite this, a return of the rotary as a range extender looks probable. Besides the dates fitting with Mazda's electric plans, there are other tidbits from the past that support the idea. Mazda has been experimenting with the idea for years, and even created a functioning Mazda2 EV with a rotary range-extender. The company has also filed patents in the U.S. for the setup as recently as last year, and there have been other recent rumors.

What a 181-horsepower 2019 Mazda MX-5 Miata means for us, and you

Last month, we reported on a VIN filing dug up by Road & Track that showed that the 2019 Mazda MX-5 Miata's 2.0-liter Skyactiv-G engine would get a power bump, from 155 to 181 net horsepower. As for how the 2019 Miata would make that extra power, we heard rumors it'd utilize a new cylinder head allowing higher revs, accounting for that extra power. Now we have what appears to be a leaked document from Mazda Canada showing exactly where that extra power comes from. According to the document posted at Miata.net (registration required to see the image), Mazda will alter camshaft lift and valve size on both the intake and exhaust side, fit freer-flowing exhaust, and smooth and enlarge the piping on the air intake side. There are also internal engine modifications: lighter pistons with lower crowns for better swirl in the combustion chamber, lighter connecting rods, and a crankshaft balanced for higher-RPM operation. All those extra revs mean extra vibration and noise, so Mazda will ditch the single-mass flywheel for a "low-inertia" dual-mass flywheel – which will attempt to find a nice balance between DMF damping action and SMF directness. Overall, it's a pretty serious engine revision with some driveline changes that will heavily affect the driving characteristics of a fantastic driver's car. Contributing Editor James Riswick and Senior Editor Alex Kierstein, both well versed in Miatas past and present, are here to analyze what this could mean for the little roadster. James Riswick: I don't know much about them lighter crank combustion rods, but I for one welcome the news of more power to the Miata. The jump from 155 to 181 seems like a very prudent Mazda-like thing to do, accomplishing that task through various aforementioned technical wizardry as opposed to slapping on a turbocharger, exclaiming "yee-hah" and calling it a day. Alex Kierstein: That's true. I'm wary of additional power, but you do make a good point that at least this is the right way to do it. Going all-motor will keep the bright responsiveness of the engine intact. But higher revs might make power delivery peakier. Frankly, I'd be ok with moving the torque and horsepower peaks up a bit in the rev range, making it a bit more work to access the engine's sweet spot. The dual-mass flywheel should also help if low-end torque suffers, so less stalling in traffic. JR: Did wonders in the 911 and 718s.

Mazda Hazumi Concept shows up ahead of Geneva

Last week, Mazda officially teased its Geneva-bound Hazumi concept, showing little more than an aggressive headlamp design. But now, thanks to the magic of the Internet, another rendering of the Hazumi has appeared on the web, and, well, it's totes adorbs.
In Mazda's original release from last week, we were told that the name "Hazumi" means "spring up" or "bound" in Japanese, and is "particularly well-suited to a small car that appears to be bursting with energy." And now that we're getting a nearly full glimpse of the thing, we absolutely have to agree. The company's Kodo design language offers aggressive style in a cute little shape, and the usual raft of concept car-spec treatments (no mirrors, huge wheels, etc.) make it look even more comical and delightful.
Indeed, the Hazumi is understood to preview the next Mazda2 subcompact, and if this concept car points the way forward for Mazda's tiniest hatch, consider us totally geeked. Mazda is also set to debut its new 1.5-liter Skyactiv-D diesel engine at the Geneva Motor Show next week, and while the company hasn't confirmed if that powerplant will make its way into the next Mazda2, it sure makes sense, at least overseas. Stay tuned.
