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 presages next Mazda2

Looks like Mazda's big Geneva Motor Show debut is actually something quite small. Teased here, the Hazumi concept "points the way to the future" for the brand's subcompact offering, the Mazda2. Details are slim as of this writing, but from what we can see in the image above, the Hazumi will use the same Kodo design language found on the Mazda3, Mazda6 and CX-5. We're big fans of this styling direction, so we fully expect the concept to be quite an attractive little number.
Hazumi means "bound" or "spring up" in Japanese, with Mazda saying this nomenclature is "particularly well-suited to a small car that appears to be bursting with energy." In other words, say goodbye to the friendly faced Mazda2 we've enjoyed since it launched in the United States in 2010. Instead, prepare for something decidedly more assertive, hopefully improving upon the already-great driving dynamics of the current subcompact. If we're honest, we can't wait.
Mazda will also use the Geneva show to debut its new small-displacement, 1.5-liter Skyactiv-D diesel engine. The automaker hasn't confirmed that this new fuel-efficient powerplant will be part of the Hazumi concept package, but considering the two are debuting alongside each other, it would seem to make sense. As for whether or not this engine could come stateside when the next Mazda2 launches, we're not holding our breath for that, especially considering the company's current woes with US-spec diesel engines.

Hyundai, Mazda and Ford offering support to victims of Colorado flooding

Hyundai, Mazda and Ford have initiated programs to aid victims of the recent floods across Colorado. Hyundai is stepping in to give help directly to drivers, offering those with flood-damaged vehicles a $750 credit on a new Hyundai. "At this stressful time, the last thing flood victims should be concerned with is how they are going to replace their water-damaged or destroyed vehicles," Dave Zuchowski, executive vice president of Hyundai's American sales, said.
The Hyundai program will run from September 18 through the end of October, and will cover all citizens in counties declared disaster areas by FEMA. Residents will need to provide proof of residency and a letter from their insurance company describing the damage to their vehicle.
Mazda, on Friday, announced that it'd be donating $25,000 to the American Red Cross and a further $15,000 to the Humane Society of Boulder Valley, in the name of disaster relief. Mazda's President and CEO, Jim O'Sullivan, said, "The flooding across the states of Colorado, Texas and New Mexico has been absolutely devastating for not only the people living there but their four-legged loved ones as well. Mazda hopes that those in need can get the help they deserve through such great organizations as American Red Cross and Humane Society of Boulder Valley."
