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.

2015 Mazda2 spotted in Japanese magazine

The styling changes at Mazda are proceeding at a fairly quick tempo. The CX-5 was unveiled, followed by a refreshed CX-9, the excellent Mazda6, and most recently a new Mazda3. This all happened over the course of less than two years, which in the auto industry is like a long week.
Now the Mazda2 is getting its revamp. Thanks to a magazine scan from Japan, we now have our first look at the new sub-compact, called the Demio, in its home market. Mazda's familial front end has been fitted, and it doesn't look quite as suited to the smaller car. Lacking the long-hood look of the Mazda3 and Mazda6, the new styling looks overly rounded, almost bulbous from our angle. It's still attractive, but the shape is kind of off-putting compared to the chiseled faces of the 2's big brothers. We'll concede that the folded magazine page may have something to do with it, however.
The next-generation 2 should adhere to Mazda's Skyactiv philosophy, which means we can expect a highly efficient four-cylinder engine, although it's impossible to say if Mazda will do away with its smallest offering's one-engine strategy. Considering the Mazda2 will be riding on a shortened version of the CX-5's platform, we'd expect some degree of mechanical parts sharing, regardless of how much the larger platform needs trimmed. Perhaps a detuned version of the 2.0-liter, Skyactiv four-cylinder could be under the 2's hood?
