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.

Feds investigating Mazda CX-9 over suspension problems

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2007-2008 Mazda CX-9 because the lower ball joint in the front suspension can potentially separate while driving. An estimated 54,000 examples of the crossover might be affected. The investigation was prompted by six complaints of this happening on the road. Because the complaints are coming more rapidly as of late, NHTSA thinks the issue could be getting worse. The problem also appears to be more prevalent in states that use salt on their roads in the winter. None of the failures caused any injuries, and all but one happened at 20 miles per hour or slower. NHTSA's preliminary evaluations "assess the scope, frequency, and safety consequence" of a potential problem and can sometimes lead to recalls.

SUMMARY: The Office of Defects Investigation (ODI) has received six (6) complaints (VOQs) alleging incidents of front suspension LBJ separation in MY 2007 through 2008 Mazda CX-9 vehicles. The reports appear to show an increasing trend. One of the separations allegedly occurred at 40 mph and the other 5 incidents occurred at speeds between 0 and 20 mph. The first VOQ was received in October 2013, followed by 2 reports in late 2014 and 3 reports in the first 5 months of 2015. Four of the VOQs are from states using high volumes of road salts (?salt states?) which, for purposes of this investigation, include: Connecticut, District of Columbia, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The other VOQs were from northern Virginia, which borders the ?salt state? region, and South Carolina. ODI also identified EWR field report data related to the alleged defect in the subject vehicles. A preliminary investigation is being opened to assess the scope, frequency, and safety consequence of the alleged defect. The six VOQs associated with this investigation are: 10717510, 10714469, 10695142, 10668978, 10640541, and 10546535.

Full 2016 Mazda MX-5 Miata pricing released

Take heart, roadster fans. The first 2016 Mazda MX-5 Miatas due for the US are now in production. To go along with that milestone, the Japanese automaker has finally released full pricing for the fourth-generation Miata. As previously revealed, the 2016 Miata in the base Sport trim starts at $24,915 (plus $820 destination), and for that outlay buyers get a 2.0-liter four-cylinder making 155 horsepower and 148 pound-feet of torque that's matched to a six-speed manual. The convertible comes standard with features like LED lighting and a Bluetooth-equipped audio system. For $1,075 more on all models, customers can spec a six-speed automatic gearbox, and keyless entry is another $130 but standard with the auto 'box. One rung up is the Club trim for $28,600, and it improves things with 17-inch wheels, a more aggressive body kit and a seven-inch touchscreen infotainment system. Order the manual trans, and the roadster gets a limited-slip differential, Bilstein dampers and a shock-tower brace. There's also a $3,400 package to make this version of the convertible even sportier with 17-inch BBS wheels, Brembo front brakes, side sill extensions and a rear bumper skirt. Among the regular trims, the top rung is the Grand Touring for $30,065 that adds luxuries like heated, leather seats, automatic climate control, rain-sensing wipers, and adaptive headlights. Mazda's i-Activesense is also standard and includes blind spot monitoring, rear cross-traffic alert and lane-departure warning. Finally, there's the Launch Edition, which is limited to 1,000 units, and it sells for $30,495 (or $31,570 for an automatic). All of them come in an exclusive combo of Soul Red with Sport Tan leather, and buyers get all of the Grand Touring's kit, plus standard keyless entry. The order site for these special roadsters opens on May 5, but hopefuls can pre-register now for a reminder. The first 2016 Miatas should hit dealers in late summer. That should provide some time for top down driving fun before it gets too cold.
