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:

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Mazda CX-6: How a wagon could sell better than the Mazda6

There is no Mazda CX-6. It doesn't exist, nor have we talked to anyone at Mazda about its existence. However, let me now say that there SHOULD be a Mazda CX-6, or to put it another way, a Mazda6 Wagon that's been Allroad-ified with a modestly raised suspension, plastic body cladding and all-wheel drive. You know, the way Americans prefer their wagons. During the Regal TourX launch, Buick's product planning folks pointed out that such a crossover wagon (let's go with that term for now) filled a market niche that's really not being satisfied. One that's more stylish and luxurious than a Subaru Outback, but more functional and less expensive than an Audi Allroad. It would cater to people who seek something different from the norm, both in terms of brand and body style. Sure, it's certainly not a big market niche, but it is seemingly growing. Well, if Buick is indeed onto something and that growth continues, then Mazda could most definitely go after that same market niche. Sure, it's a small niche, but all three Mazda6 generations have sold in such minuscule numbers (33,402 in 2017), why not try something completely different? I could easily see a CX-6 outselling its sedan sibling. Such a Mazda crossover wagon would only have a Buick and Subaru as competition, as opposed to trying to draw customers away from the Honda Accord, Toyota Camry and every other midsize sedan at a time when the entire segment is hemorrhaging sales. It would also nicely complement a lineup of crossovers that includes the CX-3, CX-5 and CX-9, providing yet another alternative to entice customers. View 30 Photos Let me also say that, having driven both the Regal TourX and a Mazda6, that the two could be cross-shopped. I'd argue the Mazda actually has a more luxurious cabin than the supposedly "premium" Regal, while Mazda's new turbocharged 2.5-liter (250 horsepower, 310 pound-feet of torque) outdoes the Buick's potent 2.0-liter. Meanwhile, the Mazda6's standard, naturally aspirated 2.5-liter (184 hp, 185 lb-ft) should offer comparable fuel economy as the Subaru Outback (28 mpg combined) without making you suffer through a CVT. Now, as for adding all-wheel drive, the Japanese market version of both the sedan and wagon (known as the Atenza) can apparently be had with it. Can it be packaged with the turbocharged engine? That's another question, but all the other pieces are seemingly in place to bring the Mazda6 wagon to the United States.
