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.

Next-gen Mazda MX-5 Miata mule spied 'Ring testing

Fans of simple, lightweight motoring, rejoice - we now have images of the next-generation Mazda MX-5 Miata undergoing testing at der Nürburgring Nordschleife. Now, to be fair, this isn't some lightly camouflaged example that will give us a great peak of what the next Miata, which will also become the next Alfa Romeo Spider, will look like. This is a mule, with the new bits hidden under a current Miata's body. That doesn't mean there aren't a few scraps of valuable information here, though.
According to our flock of camera-toting spies at the Nürburgring, the next Miata is likely to grow a bit, as new models are wont to do. In particular, it will be longer and wider, and the wheelbase is likely going to be stretched, based on the shape of the wheel wells and doors. Both of those factors will add more space in the cabin.
Those are the big indications provided by these photos, but while the MX-5 might be growing, it's a safe bet based on these images that it, and the (likely pricier) Alfa, will retain the classic, long-hood, short-deck styling that so typifies rear-drive roadsters.

Mazda goes on engineer hiring binge as recovery picks up speed

Japan's larger automakers - companies like Toyota, Honda and Nissan - have tremendous engineering talent at their disposal. That's largely because, selling as many cars as they do, they've got more revenues to tap into. Logic might dictate, then, that smaller automakers like Mazda, which no longer has the deep pockets afforded to it by its former partnership with Ford, might have less of a budget and workforce for engineering. But Mazda has been raking in record profits, and it plans on cashing those revenues in by hiring a substantial new pool of engineers.
According to Automotive News, Mazda is preparing to hire as many as 185 new engineers over the next two years - almost four times as many as the 50 engineers it previously targeted. Many of those engineers will be put to work developing the second-generation, Skyactiv 2 technologies that are on the drawing board while the first round of Skyactiv features are still being rolled out.
The boost in recruitment is enabled by a positive fiscal year that ended last March, marking the first profits Mazda had logged in four years. Sources anticipate that the fiscal year culminating at the end of this month will mark the company's most profitable yet, netting over a billion dollars to eclipse the fiscal year that ended in 2008 when it recorded $872.5 million in profits.
