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 brings slick sports-car concept to Tokyo

Mazda teased a slick spots-car concept Wednesday that will debut at the 2015 Tokyo Motor Show. The as-yet unnamed concept promises to blend elements from the company's heritage with a sleek and modern shape. It apparently takes the form of a front-engine, two-door coupe – always a favorite configuration – with a sloping roofline and classic hood-to-greenhouse ratio. It'll be displayed alongside the Koeru concept (which returns home for its Japanese debut), a handful of MX-5 Miatas, and a classic 1967 Cosmo Sport 110S – the marque's original, rotary-powered sports car. We have a good feeling that it's the latter from which the new concept principally draws its inspiration, albeit with different dimensions than the long-tailed original - and hopefully a little RX-7 thrown in for good measure. We'll have to hold on a while longer to find out, but we're looking forward to seeing the finished product. Mazda to Unveil New Sports Car Concept at Tokyo Motor Show -- Japan-debut of Mazda KOERU and racing-spec Mazda Roadsters among fourteen models on display -- HIROSHIMA, Japan, Sept. 29, 2015 /PRNewswire/ -- Mazda Motor Corporation will hold the world premiere of a new sports car concept model at the 2015 Tokyo Motor Show, which runs from October 30 through November 8.*1 A total of 14 models will be on display at the Mazda stand, including crossover concept Mazda KOERU making its first appearance in Japan, two racing-spec Mazda Roadsters (known as Mazda MX-5 outside Japan) and the Cosmo Sport (110S outside Japan), first introduced in 1967. The design of the sports car concept to be unveiled in Tokyo is modern but maintains a sense of lineage and authenticity, appearing almost to condense Mazda's entire history of sports car development into a single model. In line with the company's theme for the Tokyo Motor Show this year, "Accelerate toward our dreams," Mazda will make an appeal for the brand's unique approach to driving pleasure. In addition to the sports car concept, Mazda KOERU will be on display along with new-generation models featuring SKYACTIV Technologies and KODO—Soul of Motion design. A motor sports exhibit will feature racing-spec Roadsters and the Cosmo Sport will complement a heritage display showing Mazda's history of convention-defying engineering.

2016 Mazda MX-5 Miata won't get power folding hardtop

Following the reveal of the 2016 Mazda MX-5 Miata, more and more details (and rumors - oh, the rumors) are coming out regarding exactly what's in store when the car finally goes on sale. Our own Chris Paukert had plenty to say about the exterior and interior, and we've now seen the first photo of the engine. But a new report from Automobile sheds even more light on the 2016 Miata - specifically, that the power folding hardtop model won't be available, at least initially.
Automobile reports that the 2016 MX-5 will only be offered with a cloth top, and an insider confirmed that the mechanism is light and accessible enough that it can be raised and lowered with one hand from inside the car. Mazda officials would not comment on the availability of a hardtop in the coming years.
That said, a hardtop Miata isn't out of the question. There will likely be some sort of fixed roof available - even as a one-piece, lift-off accessory - if only for club racing. Also, remember that the current NC Miata's hardtop is the only one on the market that doesn't take up any additional trunk space, so it's an attractive proposition for buyers. Currently, the power hardtop is only offered on the Club and Grand Touring MX-5 Miata trims.
