Will the Mazda2 be offered as a PHEV with a rotary engine range extender?

Mazda2 RE Plug-in hybrid

Every few months, it seems a rumor crops up about plans from Mazda to revive the rotary engine. Last November, its CEO said the only way another one could happen is if the project was profitable, and then a month later the automaker showed off the Mazda2 RE Range Extender with a 330cc Wankel engine mounted in the rear. Now, Australian auto site Motoring reports that the PHEV may actually make production in the next-gen Mazda2 sometime after it’s initial launch.

Martin Benders, managing director of Mazda in Australia, spoke to Motoring about the company’s future with hybrids and basically reiterated what the CEO said last year. The Japanese automaker only plans to offer electrified powertrains in places where they can sell in sufficient numbers to be profitable, like Japan.

Mazda has been playing with the rotary range-extender idea for years. In the RE prototype, the engine was exclusively used to charge the lithium-ion batteries when they were running low, and a 100-horsepower electric motor provided all of the propulsion. It gave the little hatch an estimated range of about 250 miles. The company reportedly took inspiration from its Skyactiv engines to make the Wankel have lower friction and a lighter weight.

The next-generation Mazda2 is rumored to debut during the Paris Motor Show wearing Mazda’s Kodo design language. While the hybrid supposedly won’t be part of the initial launch lineup, the internal combustion powertrain lineup will consist of gas and diesel versions of Mazda’s 1.5-liter Skyactiv four-cylinder. However, the new diesel version is not likely to be available in the US.

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.

Its development was said to be born from dissatisfaction of 70 percent of Mazda2 BEV owners in Japan who said they weren’t happy with the 124-mile range of their electric car even though they never needed more; however, such a car was hinted at by the previous Mazda CEO at the 2012 Moscow Motor Show. AOL UK drove the range extended version in November and found it to be a fine experience, with Mazda engineers at the event putting such technology at least three years out while stressing that the test car is just that, and not scheduled for production.
