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 version of Mazda MX-5 Miata to be called 124 Spider

Fiat has a definite use for its recent US trademark on the 124 Spider name, and it's something that should make many performance fans quite happy. FCA CEO Sergio Marchionne confirmed to Auto Express that the Italian brand's future roadster would bear the classic name. Auto Express reportedly asked Marchionne directly about the convertible at the 2015 Geneva Motor Show. The CEO said: "Do we want to do it now?" After another executive verified the name, Marchionne responded: "There you go – a world class premiere right in this room!" Autoblog reached out to Fiat Brand communications boss in the US Ariel Gavilan for more information, and he verified the story. Gavilan said that brand head Olivier Francois confirmed the 124 Spider name to international media during a briefing in Geneva. FCA isn't going quite so far as officially confirming that the 124 Spider shares a platform with the latest Mazda MX-5 Miata, but that's almost a certainty. The two automakers jointly developed the chassis, and the original plan was for it to underpin an Alfa Romeo. However, Marchionne didn't want an Alfa assembled outside of Italy. Fiat even hinted at this possible change as far back as the corporation's five-year plan last summer. Insiders tell Auto Express that the 124 Spider reportedly carries retro-inspired style, and hopefully, that means the roadster evokes the look of the original 124 Sport Spider (pictured above) by Pininfarina. Fiat allegedly is also aiming for a weight less than 2,205 pounds, and the engine range is likely comprised of versions of the brand's 1.4-liter turbo. The mill already pumps out 160 horsepower and 183 pound-feet of torque in the Fiat 500 Abarth in the US. According to Auto Express, Fiat and Mazda have an agreement to launch the Miata in 2015 and the 124 Spider in 2016. A hotter Abarth version could come along eventually, too. Related Video:

Mazda hopes to return to Le Mans

Mazda has been away from the winner's circle at Le Mans for some time now. But it could be preparing a return to the forefront at the famous French endurance race in the near future. That is, at least, if the racing enthusiasts within its ranks get their way. "I know that the expectation for us to return to Le Mans is high. I can imagine a day when Mazda returns," Nobuhiro Yamamoto told Top Gear at the Goodwood Festival of Speed this past weekend. "I hope - as with many other Mazda fans - that we go back to Le Mans." His words hardly serve as confirmation of the Zoom-Zoom brand's intentions, but they certainly speak rather loudly to a desire within its ranks. They hardly come out of left field, either. Yamamoto-san is arguably the man best positioned to spearhead such a campaign – or would at least be best informed if such a campaign were underway. He's currently the program manager for the MX-5, and decades ago was the racing engineer behind the 787B. That Group C prototype racer represented Mazda's last major effort at taking top honors at Le Mans, and take them it did when it won the race outright in 1991. The Japanese automaker was out in force this past weekend at Goodwood, the event's central sculpture honoring Mazda's racing history, and its presence only fueling rumors that it could be preparing a renewed assault on endurance racing – potentially once again under rotary power. The 787B, motorsport history buffs will tell you, represented the first and last time to date that a Japanese manufacturer won the 24 Hours of Le Mans. Although Toyota has been competing with Audi and Porsche at the front of the field with the TS040 Hybrid, it has yet to win the key race, despite having taken the FIA World Endurance Championship last year. "Everyone at Mazda would love to see the only Japanese company to ever win the 24 Hours of Le Mans return to the famed twice-around-the-clock classic," a spokesman for Mazda's North American motorsports department told Autoblog by correspondence. "Whether that'll actually happen isn't something we can discuss at this time, but, given our historical and current involvement in motorsports, our interest in the event should be no surprise to anyone. We agree with Yamamoto-san when he says he hopes it happens." So while Mazda may not be ready to confirm the prospect of its return to Le Mans, it certainly isn't ruling it out, either.
