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.

The redesigned 2019 Mazda3 moves way upscale

Mazda didn't lie — the 2019 Mazda3 is a gently reworked production version of the Kai concept shown at last year's Tokyo Auto Show. In hatchback and sedan forms, you'll still quickly peg this a Mazda3. The dimensions barely change: The wheelbase grows by an inch, but the hatchback width and length carry over, while height decreases by an inch; the sedan is the same width but 3.2 inches longer and 0.7 inches lower. Nevertheless, the look and details have evolved throughout, yielding a much more potent and piercing hatchback, and a more sophisticated, accomplished sedan. Instead of using hard shoulder and swage lines to "draw" contour onto a flat profile, Mazda designed a car with contours that create real shoulders and hips. Shedding the illusion of surface depth for reality redefines the look and presence of the Mazda3. The new model erases the hash of lines and embossed panels in back of the current car so that the S-curved hatch has only its shutline for framing. After that, the highlights enhance the theme. On either side of the larger grille, single-lens headlamps get new accents; instead of a just plain silver bar, streaks of amber turn signals decorate the more dimensional units. The contoured taillamp housing holds highly structured, highly embellished twin circles that probably look even more sinister at night. On the sedan, those naughty taillights are surrounded by a refined rear valance with a more angled, muscular lip along the trailing edge. It's the same inside, a design based on results of Mazda's in-depth studies of human mechanics. The flatter instrument panel stresses clean lines along the horizontal. Trimmer steering wheel spokes with silver buttons line up with the central span across the dash housing the climate control buttons and vents. The new shift panel sits higher and more forward, making it easier for the driver to move a hand from the steering wheel to the lever. To raise perceived luxury, the center tunnel trim is a clear layer laid over a laser-engraved black layer, said to produce a "look of deep transparency," and similar to the effect found on the new BMW X5 and X7. The cupholders are now in front of the shifters, and the armrest is longer. There's no mention of that digital gauge cluster that leaked earlier this year, though. Buyers who opt for fabric will get a new "Greige" hue, a mix of gray and beige. Mazda designed a new leather grain with creases of varying depths and shapes depending on where it's placed.

Flyin' Miata is building a V8-powered MX-5 ND

It's cold in many parts of the country, but this V8-swapped 2016 Mazda MX-5 Miata that Flyin' Miata is developing has us dreaming about throwing on a parka and taking a very brisk drive. This beast is the product of the talented folks at Flyin' Miata, but we can't get too excited just yet. According to the company's brief Facebook post, this is just a dummy V8, placed under the Miata's hood to confirm fit. Judging by the photo, the engine fits like a glove. "There's still a long way to go before this is a real thing," Flyin' Miata writes, but the company admits everything looks "very promising" so far. The post doesn't mention any details about the estimated specs, but Autoblog reached out to Flyin' Miata for more information about this intriguing build. Keith Tanner, one of the mad scientists who shoehorns V8s into Miatas at the Colorado outfit, told us that Flyin' Miata is looking at both the LS3, which will provide between 430 and 525 hp, and the LT1 which is 460 hp out of the box. A supercharged LT4 is also being considered, but as Tanner put it, "that might be a little nuts" in a car as light as the ND. In any of these engine configurations, Tanner estimates the V8-swapped ND should comfortably be a sub-4 second to 60 mph car. The transmission will be a Tremec T56 Magnum six-speed manual. The suspension, brakes, fuel system, cooling system, and the chassis itself will all be beefed up to handle the power, as per normal FM practice. The one question mark is the rear end, as the ND's existing one simply won't be up to the task of putting that much horsepower to the ground. The 2016 Miata was one of the best cars we drove in 2015, but Flyin' Miata knows how to turn a standard MX-5 into an absolute hotrod with the company's LS3 V8 conversions for earlier models. Imagining the more modern chassis from the latest generation with a massive dollop of more power is an exciting thought. We can't wait to see how this project turns out. Related Video:
