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.

2016 Mazda MX-5 Miata first in-car observations

We've had few days to digest the all-new 2016 Mazda MX-5 Miata since the roadster was first revealed on Wednesday evening when we offered you our first impressions. Since that time, we've gone back and looked at the car a number of times in person here in California, and we've even seen it briefly run under its own power (okay, it was more of a saunter). What we didn't get the chance to do at the reveal, however, was sit inside the car. We've since been able to remedy that, and while we haven't been allowed to drive the new roadster, we do have some initial in-car impressions to share with you.
First, the location and feel of the major controls is quite excellent. The three-spoke steering wheel is an MX-5 specific item - it's not shared with any other Mazda. That's vital, because others would likely be too big in diameter or have the wrong rim thickness. The wheel's redundant controls seem to be well laid out and the airbag boss is very small. The column tilts, but unfortunately and somewhat inexplicably, it still doesn't telescope.
Pedals are well-spaced, and the six-speed manual has the same short throws and positive engagement that we've come to know and love.

Even Ferrari swept up in latest Takata recall expansion

The scope of Takata's deadly airbag problems continues to widen. Eight manufacturers announced recalls Friday that affect more than 12 million vehicles, according to documents filed with federal regulators. The automakers include Honda, which is recalling 4.5 million units, Fiat Chrysler with 4.3 million, Toyota with 1.65 million, and Subaru, which is recalling almost 400,000. Some of these cars include the Saab 9-2x and Pontiac Vibe that Toyota and Subaru made for General Motors. Mazda will recall 730,000 vehicles and Nissan has 400,000 affected units. The smallest numbers were posted by Mitsubishi, with 38,000 Lancers manufactured from 2006 to 2007, and as a noteworthy high-end manufacturer, Ferrari is calling back 2,800 vehicles. These are all US-market cars. Beyond America, the Japanese Transport Ministry has announced seven million additional vehicles will be recalled, which means 19.6 million vehicles across the globe are affected by recalls announced. The defects have been traced to an insufficiently manufactured airbag inflator, which lacks a drying agent that would prevent the inflators from deteriorating over time. Thirteen deaths have been linked to the faulty airbags, which have become unstable and are prone to exploding and showering vehicle occupants with lethal amounts of metal shrapnel. A private equity firm, KKR & Co., has been named in a possible buyout of the struggling Takata.
