2021 Mazda3 to gain a turbocharged engine, finally, probably

Buckle up, Mazda fans. The Mazda3 turbo might really be happening, says a report from Jalopnik. Some details from Mazda’s dealership extranet system observed by Jalopnik suggest weÂ’ll see a 2021 Mazda3 turbo in both sedan and hatchback form. We donÂ’t have eyes on the documents ourselves, but the report says both the sedan and hatchback versions will be all-wheel-drive only with no option for front-wheel drive. In addition to that, it looks like the turbo models will be exclusively automatic, as theyÂ’re both only listed as “6A” in MazdaÂ’s system. Sorry to break the hearts of those who were hoping for a manual turbo. The hatchback manual with the naturally aspirated 2.5-liter from the modelÂ’s first two years appears to be sticking around for a third, in case you were worried. There is one minor mystery that's a possible glimmer of hope for someone wanting more performance, though. The report says that a “MAZDA3 HB PP TURBO” is listed in the docs. Our hearts are yearning for the PP to stand for Performance Package, but it probably stands for “Premium Package.” ThatÂ’s the name of MazdaÂ’s highest trim Mazda3 right now, and itÂ’d make sense to offer the turbo engine on the upmarket model. The last we heard on this front was from a report published over a year ago. It suggested MazdaÂ’s 2.5-liter turbocharged four-cylinder as a possible drop-in. That motor makes 250 horsepower and 310 pound-feet of torque on premium fuel and would be a big upgrade to the 186 horsepower and 186 pound-feet of torque made by the naturally aspirated 2.5-liter under the hood now. Without a manual, the obvious transmission would be MazdaÂ’s traditional six-speed automatic. ItÂ’s a solid transmission for cars like the Mazda6 and CX-5, but itÂ’s not meant for sports cars, as we recently found in the automatic Miata RF. So no, this Mazda3 turbo wonÂ’t be a Mazdaspeed. It would simply be a quicker Mazda3, and while we can still pine for a true Mazdaspeed, this will be a welcome addition to the lineup. ThereÂ’s even more ancillary news in the report, too. The docs that Jalopnik saw say weÂ’ll be getting a Mazda3 with a 2.0-liter four-cylinder in 2021. That one has to be the Skyactiv-X engine weÂ’ve been patiently waiting for. It has already launched in Europe, but was delayed in the U.S. Those 100th Anniversary Edition Mazdas get a callout, too. The Mazda3 version of that is reportedly set to be equipped with the turbo engine, making that particular model even more enticing.

Mazda G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.

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
