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 still really wants to bring diesels to America

Mazda's Skyactiv program has delivered much of what it promised for the brand's latest crop of products, namely great fuel economy and excellent driving dynamics. However, the Skyactiv diesel engine has yet to reach our shores. It's been promised ever since the new Mazda6 showed up here for the 2014 model year. According to a new report from Automotive News, Mazda's CEO Masamichi Kogai said that the Mazda Skyactiv D diesel powertrain is still set to make an American appearance. He told Automotive News that there is an internal timeline to get it to the States, and while he didn't reveal the timeline, he said he wants it to come here before he steps down as CEO. The powertrain is offered elsewhere, so it fits in the company's current vehicles, but the US has specific regulatory hurdles, and the engine's extra cost has to make sense from a sales and volume perspective. We doubt VW's diesel scandal helped the engine's sales pitch, either. Automotive News also reports that the next generation of Skyactiv designs and engines are also on their way and will advance and improve on the current generation's strengths. Engineers revealed to Automotive News that they expect a 30 percent improvement in efficiency and are developing an engine with the sky-high compression ratio of 18:1. This impressive ratio could be a further indication of Mazda's pursuit of homogenous charge compression ignition (HCCI) engines. Mazda has had plenty of success with its strategy of making very efficient internal-combustion engines, but there are some concerns that the company can only improve so much. The main worry comes from the company's lack of investment in hybrid and electric powertrains. Even Mazda's North American CEO Masahiro Moro expressed concern about meeting a 54.5 mpg mandate for 2025. That mandate will no longer take effect, but increasing fuel economy requirements will always be an issue. Related Video:

Takata airbag recall spreads to China with 42k Mazda sedans

The scope of the problem with the faulty airbag inflators from Takata continues to broaden and is now reaching China, as well. Mazda is recalling 42,732 Mazda6 units there, produced by its local joint venture partner China FAW Car Company, to replace the front passenger airbags. It comes as part of Mazda's recall of nearly 160,000 vehicles worldwide, including about 34,600 in the US, according to Reuters.
This is the same problem that caused seven automakers in the US to recall an estimated 2.1 million vehicles in late June. The airbag inflators can potentially explode instead of deploying the airbag, which hampers the bag's inflation. In some cases occupants are also hit by the metal shrapnel, which can cause further injuries. In the US, Mazda is repairing the 2003-2007 Mazda6 (pictured above), 2006-2007 Mazdaspeed6, 2004 MPV and 2004-2008 RX-8 originally sold in or currently registered in Florida, Puerto Rico, and Hawaii.
This is hardly the first instance of this issue. Since 2001, there have been 20 recalls tied to the exploding airbags supplied by Takata. The problem is possibly linked to the propellant in the inflators, but there's no conclusive evidence of that yet. Most of the automakers in the US limited the most recent recalls only to a few humid states because moisture potentially exacerbated the problem.
