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.

Autoblog Podcast #523 | BMWs, Trackhawk and Mazda's new engine technology

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Joel Stocksdale. We discuss a couple of BMWs, the upcoming BMW X7 three-row SUV and our short-term BMW M760i with a turbocharged, 600-horsepower V12. We also cover the week's news, including Mazda's nifty engine technology it will roll out in the next few years, as well as pricing on the new Jeep Grand Cherokee Trackhawk. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast@autoblog.com.

Marchionne now considering 'Plan B' partners for FCA merger

Okay Sergio, just stop. With the sting of rejection from General Motors CEO Mary Barra still fresh, Fiat Chrysler Automobiles CEO Sergio Marchionne is moving on and trying to find another automaker to merge with. FCA may not be giving up hope on a merger with GM, but that doesn't mean it isn't at least considering alternatives. Sergio's so-called "Plan Bs" include the Volkswagen Group, as well as smaller Asian outfits, like Mazda, Honda, Suzuki, and Hyundai. Bloomberg reports that France's beleaguered PSA Peugeot Citroen could as a sort of "fallback" option due to its relative lack of volume, an unidentified source claimed. There are, of course, problems with each option. According to Bloomberg, Volkswagen expects complete control of a company, but the Agnelli family, which holds a large portion of FCA stock, is loathe to relinquish its stake in the company. On top of that, VAG just isn't looking to make a deal right now. Mazda, meanwhile, is enjoying a new partnership with Toyota and Suzuki is partially owned by VW. Honda and Hyundai have never expressed any interest in a partnership with a western automaker. That kind of just leaves the French then, but even that remains a long shot. As Bloomberg tells it, PSA boss Carlos Tavares is still working on a turn-around plan, and would want at least another six months to execute before even considering a deal with FCA. And even then, Tavares hasn't given any indication that he's considering a pairing.
