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.

Takashi Yamanouchi to retire as Mazda chairman

Takashi Yamanouchi has been with Mazda for a long time. He signed on with the Japanese automaker in April 1967 - one month after graduating from Keio University - and rose through the ranks over the years. By 1996 he was named to the company's board of directors. In 2008 he was named president and CEO, an office he held until 2013, after which he handed over the day-to-day reins to Masamichi Kogai and took up the seat at the head of the board room to serve as the company's chairman. But now, after 47 years working for Mazda, Yamanouchi-san is retiring at the age of 69.
During his tenure as CEO and then as chairman, Yamanouchi was credited with growing Mazda's business despite unfavorable fluctuations in exchange rates, opening the company's first plant in Mexico, and spearheading the development of Mazda's Skyactiv technologies and Kodo design language.
In his place, current vice chairman Seita Kanai will take over as chairman. The changing of the guard will take place after the annual shareholders' meeting on June 24.

'Ringbanana' Miata is improbable 9-minute Nurburgring car

The combination of being inexpensive, capable, reliable, and friendly to all skill levels makes the Mazda Miata one of the world's most popular platforms for motorsports, but the roadsters aren't exactly rocketships. What would it take to lap a ratty, first-gen example around the Nurburgring Nordschleife in less than nine minutes? We're not exactly sure, but the Ringbanana team intends to discover the answer. The project is the type of thing that gets dreamed up after a few too many pilsners: buy the cheapest running Miata available and put as little money necessary into the roadster to make it capable around the 'Ring. As the Best-Motoring-inspired intro explains, the Mazda is largely stock other than some Fulda performance tires, possibly aftermarket springs, and a stripped interior. The video above shows the baseline test, and the convertible manages a 9:21.8 circuit, which doesn't seem too bad as a start. The video below goes into far more detail about the project's genesis and its goal. Plus, the two hosts are quite entertaining when replying to the comments from the original clip. We wish them the best of luck and look forward to following along on Facebook to see what it takes to get the Ringbanana below nine minutes. This content is hosted by a third party.
