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.

Super-rare Mazda MX-5 Miata coupe pops up for sale

It's somehow fascinating that one of the most interesting developments of Mazda's MX-5 Miata roadster is the one that isn't a roadster at all. Unlike the NC and ND generations with retractable power hardtops, the second-generation NB Miata got a special coupe version with a fixed roof, done in the style of the first-generation coupe concept. We're talking very limited production numbers: just 179 of these NB coupes were made, and they were all Japanese-market models, so it's not often that one comes up for sale. Except now. Itself even more of a limited-edition car, this sportier Type S version residing in Hong Kong and advertised on Pistonheads is one of just 63 made. It's right-hand-drive, as both its Japanese market origins and Hong Kong regulations dictate, and out of the available engine variations it comes with the 1840cc unit and a six-speed manual gearbox. What's more, despite its low 30,000 miles, the 2004 fixed-roof Miata is said to be fully overhauled and restored to as-new condition. We can't imagine those coupe-specific parts such as glass and trim are easy to source, so with these extremely rare cars it's probably best to go with the best condition example you can find, if you can find one to begin with. Rust hits all old Miatas at some point. With that backdrop, the GBP30,000 ($38,700) asking price doesn't seem all that unreasonable. With the Miata's enormous enthusiast base, there are now aftermarket solutions that imitate the flowing lines of the rare factory coupe, but they do lack the strengthening that Mazda's specialty skunkworks shop put in these — and the body-stiffening roof adds a mere 22 pounds to the car's dainty overall weight. For some lucky Miata hobbyist, this particular red coupe might be the crown jewel of their roadster collection. Related Video:

Mazda poaches designer Kevin Rice back from BMW

Kevin Rice left Mazda a baker's dozen years ago, but now he's back.
A graduate of the Transportation Design program at Coventry University (just across town from Jaguar headquarters), Rice worked his way up in the industry working for the likes of Opel and Italdesign Giugiaro before landing a job at Mazda. Between 1995 and 2000, he collaborated on such projects as the RX-8 and the 1999 Neospace concept that previewed the Mazda2 before moving on to BMW, where the new 3 Series and 4 Series were among the last projects he worked on during his 13-year tenure in Munich.
Now back at Mazda, Rice has been named the Japanese automaker's new creative director, charged with further honing the brand's KODO design language from its European headquarters in Oberursel, Germany. We're looking forward to seeing what he and his design team come up with in the coming years.
