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.

Mazda Hazumi Concept shows up ahead of Geneva

Last week, Mazda officially teased its Geneva-bound Hazumi concept, showing little more than an aggressive headlamp design. But now, thanks to the magic of the Internet, another rendering of the Hazumi has appeared on the web, and, well, it's totes adorbs.
In Mazda's original release from last week, we were told that the name "Hazumi" means "spring up" or "bound" in Japanese, and is "particularly well-suited to a small car that appears to be bursting with energy." And now that we're getting a nearly full glimpse of the thing, we absolutely have to agree. The company's Kodo design language offers aggressive style in a cute little shape, and the usual raft of concept car-spec treatments (no mirrors, huge wheels, etc.) make it look even more comical and delightful.
Indeed, the Hazumi is understood to preview the next Mazda2 subcompact, and if this concept car points the way forward for Mazda's tiniest hatch, consider us totally geeked. Mazda is also set to debut its new 1.5-liter Skyactiv-D diesel engine at the Geneva Motor Show next week, and while the company hasn't confirmed if that powerplant will make its way into the next Mazda2, it sure makes sense, at least overseas. Stay tuned.

Masamichi Kogai new Mazda president and CEO

There's some executive rearranging going on in the top suite at Mazda Motor Corporation in Japan, with current CEO Takashi Yamanouchi telling reporters there "I'd like to hand over the work to younger people" now that the company has returned to profitability. Yamanouchi became CEO on November 19, 2008 of an independent Mazda that had to fight for its future in the immediate aftermath of the global financial crisis. What followed was four years of losses before finally getting back to black last year.
Masamichi Kogai (pictured) will be appointed the new president and CEO on June 25, pending approval at the company's annual general shareholders' meeting. Kogai assisted Seita Kanai with the production-efficiency initiative that Mazda called Mono Tsukuri Innovation, which worked to give export-dependent Mazda the best chance at profitability in spite of a rising yen. Kogai, lately in charge of production and purchasing, has been with the company since 1977 and worked in areas from R&D to logistics.
Kanai, who headed the Mono Tsukuri effort and was among the leadership on Skyactiv, will be promoted from executive vice president to vice chairman. Akira Marumoto will become executive VP of Mazda and assistant to new president Kogai. Yamanouchi will remain Chairman of the Board. There's a short press release below to make it official.
