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.

Mazda3 diesel under consideration for US, hybrid not so much

It's been a long time coming, but we finally clapped our eyes on the real deal, officially official 2014 Mazda3 in hatchback form yesterday. Yet there's a lot more to learn about this next-generation version of what has always been one of our favorite compacts. We know that the US version will come with one of two Skyactiv engines, but what about alternatives? Will there be any... or will the gasoline-fed four-cylinders be powerful and frugal enough to carry the day?
According to Automotive News, the answer is a definite maybe. Mazda North America CEO Jim O'Sullivan has told the trade publication that his employer will consider adding the company's well-liked 2.2-liter Skyactiv diesel powerplant to the model down the road. However, the company first wants to see how the engine fares with American consumers in its big-brother Mazda6 sedan, a model that goes on sale later this year. As for a potential Mazdaspeed3 successor, mum is still the word.
Anything else? Uncharacteristically, Mazda will build a hybrid model of its new 3. We say "uncharacteristically," because the Japanese independent has long shied away from gas-electric powertrain tech. In fact, it's gone so far as to boldly announce its aversion to the technology, with auto show banners proclaiming "Not Electric. Not Hybrid. Not A Drag To Drive." Despite all that, this new generation of Mazda3 will in fact be the company's first full hybrid production model. According to AN, however, O'Sullivan says that the company has "no plans" to sell it in the US.

Next Mazda MX-5 Miata headed for 2015 Chicago debut

Twenty-six years after it was introduced at the 1989 Chicago Auto Show, the much anticipated fourth generation Mazda MX-5 Miata will meet the press at the 2015 Chicago show. A piece in Autocar refines some of the details on the larger, lighter Miata that a Mazda insider has said will be "our best-looking car ever."
The company has relented on the quest for the metric tonne, the 1000-kilogram (2,200-pound) target too difficult to achieve in light of cost constraints. You can still expect it to lose a generous dollop of weight - Autocar says a curb weight of 1,100 kg (2,420 pounds) will still make it the lightest in its class. And Mazda will be stressing a fun driving experience through light weight and a modest amount of naturally-aspirated horsepower. Engine capacities of 1.5 and 2.0 liters are expected. Sounds familiar (and good), right?
The Miata's interpretation of Kodo design will be veer from that found on the Mazda3 and Mazda6, with "very clean and simple" lines marking out "more muscular proportions" and elongated bodywork on a longer wheelbase. A stretched engine bay will make room for the current Skyactiv engine and perhaps the future Skyactiv 2 powerplants, initial reports suggesting there could be a 30-percent increase in fuel economy from the moment it arrives.
