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:

Sweating the small stuff | 2017 Mazda CX-5 First Drive

The 2017 Mazda CX-5's door handles got their own design study. They got their own graphs, maths, and a team of people scientifically analyzing how humans interact with them. There was a whole to-do. And yet, you look at them back-to-back with their predecessors, a Spockian eyebrow reaching to the stars, and wonder what all the fuss was about. But apparently they're better. They're also perfectly illustrative of the entire effort to re-engineer and improve Mazda's best-selling model. At first, the 2017 Mazda CX-5 seems like a sensible evolution of its well-loved predecessor – there's sexier styling, a more premium cabin, and additional features, but the dimensions and engine specs look awfully similar. It certainly looks like one of those "the old car's great, let's not overthink the new one" redesigns. Except it isn't. Dig deeper and you'll see just how much meticulous work – from the door handles to the throttle response – went into making the new CX-5 a crossover that thoroughly trounces the majority of its competition. Take the efforts to make it quieter. According to Mazda's internal measurements, the sound-quelling improvements made for the CX-5's 2016 refresh already made it one of the quietest compact SUVs on the market. That apparently wasn't good enough. To what seems like an absurd degree, Mazda's engineers obsessively examined every nook, cranny, corner, and crevice to sniff out noise and eliminate it. Gaps were filled, insulation was injected, seals were added, air was redirected, glass was double glazed, and carpet replaced plastic coverings. It would seem that the Society of Persnickety Engineers is well represented at Mazda HQ. "I'm not sure how they found some of these," said Mazda vehicle development engineer Dave Coleman with a shake of his head, almost amused by the obsession and dedication of his colleagues across the proverbial hall in the sound-deadening department. (He goes over many of their enhancements in the video below.) And it worked. The new CX-5 is indeed incredibly quiet, even on San Diego's notoriously loud corrugated concrete freeways. It is quiet for a Mazda – a brand previously known for the exact opposite – and the entire segment. Even the fairly quiet 2017 Honda CR-V we drove on the same freeways on the way to San Diego couldn't match it. Actually, much of the driving experience can't be matched by a competitor.

Japan carmakers vouch for safety of some Kobe Steel parts

TOKYO — Four Japanese automakers on Thursday said they found no safety issues with aluminum parts supplied by Kobe Steel Ltd, allaying some concerns that falsified quality data on products from the steelmaker had compromised their vehicles. Kobe Steel shares surged after the car makers' statements, but the steelmaker still has to contend with a U.S. Justice Department probe, while checks continue at hundreds of companies involved in complex supply chains spanning the globe. Japan's third-biggest steelmaker admitted earlier this month it falsified specifications on the strength and durability of aluminum, copper and steel products, along with materials for optical disks. The falsifications stretch back for more than 10 years, a senior executive told Reuters this week. Since then, global automakers, aircraft companies and other manufacturers have scrambled to identify potential hazards in their products. Toyota, Honda, Nissan and Mazda said that hoods and other exterior parts used in their cars which were made from aluminum directly supplied by Kobe Steel were safe. Kobe Steel shares ended the day nearly 7 percent higher but are still down by more than a third since it announced the data falsification. Automakers are still making checks on other parts, including those that they received through their parts suppliers. "We confirmed that the materials satisfy applicable statutory standards, and our own internal standard, for key safety and durability requirements for vehicles," Toyota said in a statement. Toyota, one of the world's largest automakers, identified aluminum plates supplied by Kobe Steel for the hoods and rear hatches of Toyota and Lexus brand vehicles. Though outside the automaker's specifications, they were still safe to use. While Subaru and other carmakers said they were still investigating the issue, the announcements by Toyota, Honda, Nissan and Mazda suggest that Kobe Steel's cheating scandal may have a limited impact on product safety."SERIOUS SITUATION" Nonetheless, the company's fate hangs in the balance while checks are being carried out. It must report to Japan's industry ministry by around the end of next week on any safety concerns and provide a more extensive account of the problems a fortnight later. Industry leaders have reached a consensus that Kobe Steel is in a "serious situation," a senior Japanese manufacturing executive told Reuters.
