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.

Fiat 124 caught entirely undisguised

Dear automakers, please continue making these kind of mistakes. Thanks to what we're guessing is some lax security, the all-new, Mazda MX-5 Miata-based Fiat 124 was spotted taking part in a photo shoot near Santa Barbara, CA. The images show what we'd consider a fairly simple rebadging job. The 124 gets new front and rear clips that not only harken back to the original 124 (not to mention other Fiat roadsters, like the Barchetta), but also serves to distance this droptop from the rest of the company's US range. The similarities between the 124 and the car it's based on are even more obvious in the cabin. This is an MX-5 interior with Fiat's big, red badge on the tiller. That means the same quality materials and knob-dial infotainment system that have been so well received in the Miata. It's under the hood, though, where the Fiat really differs from its Japanese cousin. According to our spy, the vehicle shown here features some kind of two-pedal setup – probably the six-speed Euro twin-clutch used in the 500L and Dodge Dart. Don't worry, though, a six-speed stick will also be on offer. Regardless of transmission, we can expect a 180-horsepower version of the 1.4-liter, turbocharged, four-cylinder offered in the 500 Abarth. And if that's not enough good news, a dedicated Abarth model will likely arrive after launch, which our spies claim will use the 1.75-liter turbo and DCT from the Alfa Romeo 4C. While this represents a good look at the new 124, we'll probably be waiting until the LA Auto Show in November for the official look. Stay tuned.

Mazda de Mexico celebrates 100,000th car built

Automakers and their factories celebrate production milestones all the time. Some are interesting enough to report on and some aren't, but what makes this one stand out is that the plant opened less than a year ago. Just 11 months since production began, Mazda de Mexico Vehicle Operation has put together its 100,000th vehicle – in this case a Mazda2 hatchback headed for Europe. MMVO is one of three plants assembling the company's smallest model, also known as the Demio in Japan, where it is also produced, with additional assembly taking place in Thailand under a joint venture with Ford. The Mexican location also handles assembly of the Mazda3 for the Americas and for Europe. Mazda has announced that it is expanding production at MMVO by 150 percent of this year's capacity to 250,000 units per year by March 2016 as it takes on contract manufacturing for Toyota as well.
