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

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.

Mazdaspeed3 concept tipped for Frankfurt debut

The last quarter of 2015 could be a big one for Mazda as a report has emerged from Australia claiming that the company will come to the Frankfurt Motor Show in September with a near-production concept of the third-generation Mazdaspeed3, while a second-generation CX-9 will be shown a few months later in Los Angeles. Motoring.com.au ran the initial report, and although the news seems plausible, the outlet doesn't provide sources for either piece of news. Likewise, our friends at Mazda USA refused to comment on "speculation." Speculation it may be, but it's surely tantalizing considering the recent popularity of both the hot hatch and three-row crossover segments. According to the Aussies, the concept Speed3 will quickly evolve into a production model, which will launch alongside a mid-cycle refresh for the current 3. A turbocharged 2.5-liter will spit out 295 horsepower, and could have all-wheel drive. Even if only the front axle is doing the work, the MS3 will easily be able to stand toe-to-toe with hotter half of the segment based on output alone. As for the more mundane offerings, Motoring reports the long-in-the-tooth CX-9 will get a replacement in LA, although it doesn't offer much in the way of details beyond that. It should be interesting to see how the company's Skyactiv philosophy will be implemented on such a large vehicle. Perhaps the biggest surprise from the Australian report, though, are the outlet's reports on the CX-7, which will return sporting a third row of seats after its larger sibling debuts. That'd give Mazda a versatile lineup of four crossovers, with the sub-compact CX-3, the compact CX-5, the midsize, seven-passenger CX-7 and the fullsize CX-9. As we weren't able to confirm any of this with Mazda, we'd still warn that this news should be ingested with grains of salt. Still, it looks like the company could be set to make some waves in the first two shows of the upcoming auto show season.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
