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 halts sales of CX-5 due to fire risk in crashes

The Basics: Mazda will recall 264,463 examples of the 2014-2016 Mazda CX-5 in the US. The Problem: The fuel filler pipe can rupture in a rear collision. This could cause a fuel leak, which is a fire risk. Injuries/Deaths: None reported. There are also no reports of fires. The Fix: Mazda has not yet specified the repair for the problem. If You Own One: Concerned owners can get a free loaner, demo, or rental vehicle until Mazda dealers repair the vehicle. More Information: Mazda also has a stop sale on new examples of the CX-5 until the company fixes the problem.

On all 2014-2016 MY CX-5 vehicles, the fuel filler pipe could rupture during a rear collision, and could potentially cause fuel leakage. Approximately 264,463 vehicles are affected in the U.S. There are no reports of accidents or injuries occurring in the subject vehicles as a result of this condition. If a customer has concerns about driving their vehicle before the repair is available, dealers will offer a free loaner, demo, or rental vehicle. Mazda North American Operations is headquartered in Irvine, Calif., and oversees the sales, marketing, parts and customer service support of Mazda vehicles in the United States and Mexico through more than 700 dealers. Operations in Mexico are managed by Mazda Motor de Mexico in Mexico City.

Consumer Reports digs Mazda3, disses Jeep Cherokee

Consumer Reports has just rendered its verdict on two of the more important cars to launch this year - the Mazda3 and the Jeep Cherokee. Considering the value a "Recommended" rating carries with the public and the viciously competitive markets these two cars compete in, Consumer Reports' view could have some impact on their initial success.
For Mazda, that's a good thing. CR spoke quite highly of the Zoom-Zoom brand's compact sedan and hatch, testing both models, and citing the excellent fuel economy and snickety-snack manual shifter as high points. Downsides to the 3 included a ride that is agile but "nervous," a bit too much noise and a cramped back seat. Still, the 3 was good enough to earn its place in the ranks of the "Recommended."
The Jeep didn't fare quite so well, with CR calling the polarizing CUV "half-baked." Although both engines were tested, the magazine called the 2.4-liter four-pot underpowered and its nine-speed automatic unrefined and unresponsive. That's particularly damning, considering the 9AT's role in future Chrysler products, including the extremely important 200. Overall, the Cherokee missed out on the coveted "Recommended" rating.
