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.

4 automakers agree to $553M settlement of Takata airbag claims

WASHINGTON (Reuters) - Four automakers agreed to a $553 million settlement to address class-action economic loss claims covering owners of nearly 16 million vehicles with potentially defective Takata airbag inflators, according to court documents filed on Thursday. Toyota's share of the settlement costs is $278.5 million, followed by BMW at $131 million, Mazda at $76 million and Subaru at $68 million. According to a press release from Plaintiffs' Committee for Takata Airbag Product Liability Litigation, the funds for the settlement are aimed at getting more cars with faulty airbags fixed. At the time of writing, Toyota had the greatest recall completion percentage of 31.89 percent followed by Subaru with 31.37 percent. Mazda has completed repairs on 18.16 percent of affected cars, and BMW brings up the rear with 16.48 percent completion. Some settlement funds will go to an outreach campaign to increase awareness, while other funds will be used to reimburse people for any costs accrued to get their cars fixed. These costs can include rental cars, child care, lost wages, or any other reasonable costs associated with bringing in a vehicle for repairs. Furthermore, a customer support program will be funded with settlement money to handle any additional repairs or adjustments that could become necessary in the 75,000 miles following the airbag replacement. Lawsuits against Honda, Ford and Nissan have not been settled, lawyers said. Takata inflators, which can explode with excessive force and unleash metal shrapnel inside cars and trucks, are blamed for at least 16 deaths and more than 180 injuries worldwide. The safety defect has prompted recalls worldwide of about 100 million inflators by more than a dozen major automakers.

China's FAW now building all three Mazda6 generations

The Chinese auto market is one of the most interesting in the world to look at. Its automakers appear to still be figuring things out and remain open to experimentation. For example, at this moment, you can buy new copies of all three generations of the Mazda6 from showrooms there.
Mazda joint-venture partner FAW recently introduced the latest generation to China as the Mazda6 Atenza, according to Just Auto. Yet buyers still have the option of getting the previous generation as well, which is sold as the Mazda6 Ruiyi. Obviously, that isn't too remarkable - companies in the US have briefly sold two generations of the same nameplate simultaneously for brief points in the past, and the practice is much more common in developing markets. However, Chinese consumers still have the third choice, too - the first-generation model that dates back to the early 2000s, is still on offer, known simply as Mazda6.
While it would be hard to imagine selling three generations of the same models at once in the US, the idea is an interesting one. We enjoyed our long-term test of the latest generation, and the previous models weren't bad cars either, so provided there's a healthy difference in pricing and marketplace confusion is limited by differing names, we can see it working. If nothing else, it's a fascinating illustration of how broad China's developing auto market really is.
