Mazda to use rotary engine as a range-extender with its first electric vehicle

There's more news from Mazda at the Tokyo Motor Show, where the brand made a big splash, including new developments in its never-ending rotary engine saga. First, Mazda execs confirmed that the Japanese automaker will bring back the rotary engine as a range-extender and battery juicer for its first electric vehicle in 2019. But secondly, the company won't have a rotary-powered successor to its RX-7 and RX-8 sportscars in time for the company's centennial anniversary in 2020. Autoblog previously confirmed that Mazda is planning to have an EV in 2019 that will be available in both pure electric and range-extending versions. Now, the Australian website Motoring reports that the global EV will feature a powertrain similar to the experimental Japan-only Mazda2 (Demio) EV, which used a single-rotor engine as a generator to power the battery pack and increase its driving range. The publication says Mazda plans to release a series of plug-in hybrids based on existing models around 2020, then a pure electric car co-developed with Toyota and Denso in 2021 as part of the EV Common Architecture Spirit Company joint venture. A Mazda spokesman tells Autoblog the company couldn't confirm any details about future products. Meanwhile, enthusiasts shouldn't wait for a rotary-based production version of Mazda's RX-Vision concept from 2015. Motoring cites two executives who explain that the company simply lacks the capital necessary to invest in developing the new model in time for its 2020 centennial. Mazda debuted its rotary engine 50 years ago in the Cosmo Sport in part as a way to stand out from its larger Japanese competitors. The engine, which uses a spinning three-tipped rotor in place of pistons, is smaller and lighter than conventional piston engines, with a greater power-to-weight ratio and quieter, smoother operation. But it delivers less fuel economy and higher emissions — two weaknesses that could be improved via a stop-start system Mazda has developed, based on a pair of U.S. patents. The company has also been hard at work developing its next-generation Skyactiv-X engine, which uses highly precise combustion ignition technology to deliver significant gains in fuel economy and power.Related Video:

2016 Mazda2 gets EPA-rated 43 mpg highway

To paraphrase the famous quote from astronaut Neil Armstrong, that's one small step for man and one giant leap for the Mazda2. The Environmental Protection Agency (EPA) has weighed in on the new Mazda2 version, and says it gets a fuel-economy rating of 33 miles per gallon city and 43 mpg highway with a six-speed automatic transmission. Stick-shift gas-mileage figures are 31 city and 42 highway, which are still substantially better than the 29/35 rating from the most recent iteration of the model. That's about a 15-percent jump in fuel economy, people. More importantly, the Mazda2 beats out competitors such as the Hyundai Accent, Kia Rio Eco and even the Honda Fit in terms of fuel efficiency, which is pretty good company. The Mazda2 boasts a 1.5-liter four-cylinder engine. But it is the upgrade to six-speed transmissions in both manual and automatic versions that seem to be making the biggest difference in the ratings. Mazda started unveiling details about the next-generation Mazda2 last year, and last fall began production of the model at Mazda's new factory in Salamanca, Mexico. At that time, the Japanese automaker had already sold more than 2.4 million Mazda2 vehicles since the model's introduction in 1996. Related Video:

2016 Mazda MX-5 Miata 2.0L First Drive [w/video]

The 2016 Mazda MX-5 Miata is easy to comprehend. It is an enthusiast roadster in its purest form. There's no need for any sort of sales pitch. You don't have to ramp up in order to get people excited about it. Say the words "new Miata" to anyone who cares about cars, and you've immediately got their attention. And now that I have yours, I'll to cut right to the chase. It's brilliant. That's a fact I've known for a while. I drove the Japanese-spec ND Miata in Spain earlier this year, with the 130-horsepower, 1.5-liter engine that we aren't getting in the United States. The new Miata is a modern day reincarnation of the original NA that stole our hearts in 1989. It's smaller and lighter than the outgoing NC, yet boasts more interior room. It's comfortable. It looks great. And it drives like a Miata should. In other words, it's perfect. So what about this US-spec car, then? It's got more power – 155 horsepower and 148 pound-feet of torque from Mazda's 2.0-liter Skyactiv four-cylinder engine. But it's also heavier. Our car weighs 2,332 pounds, compared to the roughly 2,200 pounds of the 1.5-liter car. Yes, the ND Miata loses 12 hp compared to the outgoing NC, but it's up 8 lb-ft of torque. Plus, according to Mazda, because of the improved powerband, anytime you're under 5,700 rpm the new Skyactiv engine is stronger than the old MZR mill. It's more efficient, too. With the manual transmission, the Miata is estimated to achieve 27 miles per gallon in the city and 34 mpg highway. That a jump of six mpg in both categories compared to the old six-speed. Consider this: The Japanese-spec car uses a 130-hp engine, which I found to be perfectly adequate. The increase in power for the US-spec car mostly just balances out the extra weight, but it also improves performance on the highway. Hit the throttle in sixth gear with the 1.5 and nothing happens. Do the same with the 2.0, and there's movement. Low-end power is far more important in the US than it is in other markets, and that's why our car has the larger engine. "North America is why the two-liter car exists," engineer Dave Coleman told me. Plus, 155 hp power means you eke out the Miata's dynamics at legal speeds. 45 miles per hour in an MX-5 is a far more exhilarating experience than that same speed in any supercar. So yeah, it's not powerful. But to paraphrase Jay-Z, the MX-5 is a super car, not a supercar.
