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.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

The spirit of these 7 weird Mazdas lives on in today's cars

HIROSHIMA, Japan — When visiting the Mazda Museum in Hiroshima, housed amidst the company's main manufacturing site on the shore of the Enko River, you can follow Jujiro Matsuda's early 20th century entrepreneurial path from artificial cork manufacturer to machine and machine toolmaker, to motor vehicle producer. But probe a bit deeper into the exhibits, and you can uncover more than just a chronicle of corporate achievements: delightfully weird outliers, paragons of oddball design, engineering and marketing solutions It's looking at these delightful misfits that really illustrates Mazda's tale. You can also see precisely how many of these vintage conveyances led directly (or indirectly, or obtusely) to Mazda's most iconic American-market cars and trucks. Our seven favorite precursors, and their lovable successors, are listed below. 1931 Type TCS/Mazda B-Series Mazda's first vehicle was this little three-wheeler, powered by an air-cooled, one-cylinder motor. Because the company lacked a distribution network at the time, the trucklet was marketed by Mitsubishi; hence the three-diamond pattern on its side. All of this is very reminiscent of the company's eventual foray into the U.S. market, where its sales were spearheaded by compact pickups. The B-Series, which was one of the first Mazda vehicles available in the U.S., arrived in 1972, and stuck around through the first decade of the 21st century. Like its partnership with Mitsubishi, Mazda teamed up with stakeholder Ford to market this little truck as Ford's first small pickup, the Courier, the precursor to the Ranger. There was even a rotary-powered B-Series for a few years, but we're getting ahead of ourselves. 1968 Bongo Van/Mazda5 The Bongo allegedly was the first one-box van design in Japan, and apparently it was so popular that the name Bongo became, for a period of time, the generic metonym for the category—the way that Kleenex is a stand-in for all facial tissue. With a tiny rear-mounted engine and a planar expanse of metal to push around, it was not particularly fast, but it was both spacious and innovative. The same could be said of the brand's mini-minivan, the Mazda5, which was available for a couple of generations in the States in the Aughties. Sadly, the name 5 never caught on as a synonym for fun-to-drive family hauler, at least not yet, and the category itself (like nearly every other car category) was crushed in America by the rise of the crossover.
