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:

Mazda teases its Tokyo-bound EV again — and it's a crossover coupe

Another 15-second teaser clip, the third so far, stars Mazda's coming electric vehicle in the role of coquette. This time we get a glimpse of the body shape, and coming as a shock to no one since Mazda practically admitted it, we'll be seeing a crossover coupe on the Tokyo Motor Show floor. Mazda says there'll be a few surprises therein, though. The overall line and detailing embody "an expansion of our renowned Kodo design philosophy" at the same time as the EV "explores new directions in design." And within the "uncompromisingly simple" form we're told to expect "a unique door concept, opening your mind." Another couplet in the press release poetry promises a "friendly expression" up front for a new segment entry embodying "futuristic values and changing lifestyles." Well then. This will be Mazda's fourth electric vehicle, but the first meant for mass production. The company built a small batch of the Mazda Demio (our Mazda2) battery electric vehicle in 2012 for the Japanese market, leasing them to government and corporate customers. The following year the automaker built a Mazda Demio EV prototype with a 330-cc rotary-powered range-extender engine. After that came the e-TPV prototype that the company's used to prove out the powertrain going into this month's show car.  The urban-focused electric runner should go on sale next year in markets like Japan, China and Europe, where dense city centers negate the need for sky-high range figures; the 35.5-kWh battery is likely to return a 150-mile range at most. As foretold in the most recent teaser, the interior will deliver an airy sense of space thanks to open spaces between the driver's and passenger's seats. Zoom-Zoom will come with EV internals, too — Autocar recently drove the eTPV prototype and lauded it for being "well-planted," "original to drive" and "more like a car in the traditional sense of the word." 

Finalists for 2014 Green Car of the Year announced

The list of finalists for the 2014 Green Car of the Year has been announced, and in a genuinely bizarre twist, there's only one hybrid and no electric vehicles among the five contestants, despite the arrival of cars like the BMW i3 and Tesla Model S. Taking the place of the EVs are a pair of diesels, repping a technology that last won a Green Car of the Year award in 2009, when the Audi A3 TDI took the title. No diesel was in the running for last year's award.
Naturally, both of the diesel finalists are fielded by the Germans - with BMW's 328d and Audi's A6 TDI getting the nod. In the case of the 3 Series, BMW installed a 2.0-liter, turbodiesel, capable of delivering 180 horsepower and 280 pound-feet of torque, while returning 45 miles per gallon on the highway. Audi and its larger, 3.0-liter, V6 turbodiesel produce quite a bit more grunt, with 240 hp and 428 lb-ft of grunt, but net a very impressive 38 mpg on the highway in the A6.
Finalists for this year's awards include two diesels, three gas-powered cars and a plug-in hybrid.
