Next-gen Mazda6 reportedly getting RWD, straight-six it shares with Toyota

Last June, Japan's Best Car magazine laid out what we considered a whopper series of rumors about future Mazda developments. The mag said it had been speaking to a Toyota source on an unrelated matter, and found out that Mazda's work on a straight-six Skyactiv engine was predicated on that engine's use in Toyota Group vehicles, including Lexus models. Car and Driver has apparently consulted its own sources, and in a new report utters many of the same pronouncements as Best Car. The next-generation Mazda6, due around 2022, will molt out of its transverse engines on a front-driver platform, and be the first home for the longitudinally-mounted straight-six on the automaker's new rear-wheel drive "Large Architecture."  The gas-powered Skyactiv-X six-cylinder, a shade under 3 liters of displacement, will get help from a 48-volt hybrid system, and top output could hit 350 horsepower. A second straight-six will come in an oil-burning Skyactiv-D flavor, and PHEVs are certain to eventually factor into the equations. The sheetmetal around the bodywork will draw inspiration from the four-door Mazda Vision Coupe concept that debuted at the 2017 Tokyo Motor Show. Describing a scenario we can only cross our fingers for, C/D writes "there's a chance Mazda will mimic Lexus and put inline-six into both four- and two-door bodies," grabbing another unused concept as a design guide for the latter, the two-door RX Vision concept from the 2015 Tokyo Motor Show. C/D suspects the increasing cooperation between Mazda and Toyota will not only pay the bills for Mazda's sports sedan, but compel the Large Architecture to take a couple of side jobs in Toyota City. C/D writes, "Toyota may adopt the six-cylinder Skyactiv-X for the next-generation Lexus IS and RC." According to the recently leaked dealer report, the next-gen IS could be with us in 2021 as a 2022MY offering. Betting money seems to be on the sedan sticking with Toyota's TNGA platform and Lexus engines until a brand new model shows around 2026, though.

2014 Mazda6: July/August 2013

Our newest long-termer - the Soul Red 2014 Mazda6 seen here - arrived in my driveway at the end of June. Without hesitation, I immediately put it to work as a daily driver, carpool bus and family vacation sled, and it accomplished all of those tasks with aplomb. Now, more than 4,000 miles down the road, I am left convinced that Mazda's latest midsize sedan is one of the best in its segment.
During the past 60 days, I have subjected the Mazda6 to scorching travel across Southwestern deserts, wheezing climbs over 8,000-foot-high Sierra Nevada mountain passes and basking in the cool ocean breezes of Malibu. It traveled with four passengers and a full load of luggage from Los Angeles to Lake Tahoe, and it braved the bumper-to-bumper freeway congestion on a weekday trip down to San Diego. It accomplished everything that was asked of while hardly skipping a beat - it has only required a regular sip of unleaded fuel to keep it moving forward.

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:
