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 hits Vegas with a pair of Sixes

Despite the fact that the annual SEMA show is more of an exercise in what "could be" than what "will be," it gives automakers the chance to stretch the legs of some of its most important models. Take the 2014 Mazda6, for example - it's hardly new, having gone on sale early this year - but this year's SEMA expo marks the first time Mazda has been able to show off the customization possibilities for its sleek midsize sedan. To that end, the Japanese automaker has arrived in Las Vegas with two very different takes on its sexy Six.
First up is the Mazda6 Club Sport you see above, wearing a "motorsports-inspired" gray, black and red accent-color scheme that, as Mazda says, is "represented in not-so-subtle angular lines reminiscent of a car speeding past your line of sight." The whole car is done up in a base color of Composite Grey, and uses a Brilliant Black roof to match the similarly colored front, side and rear diffusers, as well as the rear spoiler. Mazda has fitted the Club Sport with Rays 57 Motorsport G07FXX 20-inch wheels, wrapped in Yokohama 245/35R20 tires. Powering the CS is Mazda's 2.2-liter Skyactiv-D diesel four-cylinder engine (that we'll get in the standard Six early next year), and other changes include an H&R spring kit, larger Brembo brakes and a Racing Beat exhaust.
And then there's the Ceramic 6 Concept, pictured right. The name comes from the car's Ceramic White paint, though we don't really get the Taupe Silver accent stripes. Mazda says they're meant to mimic "the linear frequency patterns found on the likes of couture dresses and flowing fabrics," but it just looks a bit overwrought to us. The Mazda6 already has so many clean lines, why add more?

2019 Mazda MX-5 Miata's more horsepower will cost less money

Mazda has already announced a power upgrade for the 2019 MX-5 Miata roadster after engineers tweaked the Skyactiv-G 2.0-liter inline-four for 17 percent more power and higher fuel efficiency than the outgoing 2018 model. Now we know the starting price for the soft-top version: $26,625, including destination charge, which is a $915 drop from the lowest-priced 2018 model. As is standard across the Miata lineup, output increases by 26 horsepower to 181 hp, with torque nudging up 3 pound-feet to 151 lb-ft at 4,000 rpm. Other new features also track with the changes previously announced for the 2019 Miata RF, including the telescoping steering wheel and standard rearview camera. But the soft-top version gets an available brown soft top for an extra $200 for the Grand Touring trim (a black soft top is standard), new package options at each trim level and optional traffic-sign recognition and smart city brake support, which offers automatic emergency braking at low speeds. Also new is that steering column, which is made of aluminum to save weight. Mazda will keep the six-speed manual as an option for all three trim levels, with an available six-speed automatic with paddle shifters and Sport driving mode. Standard features include LED head- and taillights, 16-inch wheels, Mazda Connect infotainment with a 7-inch touchscreen monitor, Bluetooth phone pairing and audio streaming, and keyless entry. Jump up to the Grand Touring trim starting at $31,675 and get 17-inch dark silver wheels, body-color interior trim, auto on/off headlights, auto-dimming driver's side mirror, rain-sensing windshield wipers, heated, leather-trimmed seats and a nine-speaker Bose Premium audio system, among other things. Mazda is also offering a $550 GT-S Package on the Grand Touring model with the six-speed manual, a front shock tower brace, limited-slip rear differential and Bilstein dampers. MX-5 Club models start at $30,485 and come standard with the GT-S Package goodies when equipped with the manual transmission. Automatic versions get standard heated cloth seats with contrasting red stitching, body-color interior trim, black 17-inch wheels, front air dam and rear lip spoilers.
