Mazda's new turbo four fits in both the 6 and the 3

Despite the size differences, the Mazda CX-9 shares a lot with its smaller car-based siblings, the Mazda6 and Mazda3. That could allow Mazda to slot its full-sizer's new 2.5-liter, turbocharged four-cylinder engine under the hood of its smaller offerings. Pardon us while we do a happy dance. "[The 2.5-liter turbo] fits in a lot of our cars, and where we're actually going to put it is another question," Mazda North America vehicle development engineer Dave Coleman told Australia's Car Advice. Coleman specified that the turbocharged engine will fit in all the same applications that can accommodate the company's 2.5-liter gas and diesel engines. "Basically, that big space we used for the bundle of snakes exhaust manifold, the turbo is in that space too. They're all packaged to occupy the same space. It's exactly the same clearance as the exhaust manifold of the other engines." This kind of logic – if Engine A is the same size as Engine B, then both should fit in Car C – is what's lead us to imagine a turbocharged Mazda6 since the new engine was announced. In short, it's great news. Mazda's 2.5-liter turbo is a hell of an engine in the CX-9, and it's hard to imagine it'd be worse in a lighter vehicle. But just because it works from an engineering standpoint doesn't mean it's going to happen. At least, not soon. "It fits. I'm not a product planner so I don't get to make that call," Coleman told Car Advice. "It's up to the product planners to decide what they're going to put it in." The most obvious application for a turbocharged engine in the 3 or 6 is as a reborn Mazdaspeed model. But don't get too excited – Coleman said Mazda hasn't even gotten as far as building an engineering prototype with this engine. We're still firmly at the theoretical stage. And that's bad news, because it gels with what we've been reporting – that Mazda will wait a generation for future Mazdaspeed models. We just stopped doing our happy dance. Related Video:

Mazda Miata 'fathers' Hall and Case offer a tour through the roadster's history

The original Mazda Miata broke onto the automotive scene in 1989 and was a huge success. However, the convertible's genesis goes all the way back to the early '80s. Bob Hall and Dean Case were among the inside men of the program on the US side, and they were on hand at Mazda Raceway Laguna Seca during the recent MX-5 event there to tell some of their stories about the project's beginning.
Hall was on the Miata project from very early on, and one of his most fascinating stories is how the convertible got its shape. The droptop wasn't necessarily going to be a rear-wheel drive roadster. There were both front-wheel-drive coupe and mid-engine concepts being considered. In fact, the classic look of the NA generation was the least favorite of the three at the sketch stage.
Hall comes off as a jokester hiding a genius mind. He has a fountain of information in his head about what a Miata should be, but it all comes down to "less is more." However, he admits that it's easy to conceive that idea, but it's much harder to actually execute it well.

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.
