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.

United States drivers buying fewer Mexican-made cars

Crossovers and pickup trucks are not only growing in market share, they're also more profitable than cars. A crossover on the same platform as a sedan retails for thousands more, despite similar components. It's one of the reasons we've seen automakers rapidly shifting production of their sedans and hatchbacks to Mexico, where cheap labor preserves the thin profit margins on these inexpensive vehicles. But as the market continues to shift in the United States, Mexico is getting burned by its lack of product diversity. The country's auto exports, which are heavy on cars, suffered a 16-percent drop last month, Automotive News reports. In total, year-over-year exports fell from 233,515 to 197,020 last month, while year-to-date exports are down by 7.4 percent, from 922,029 to 854,118. The number one culprit? America – which usually accounts for 75 percent of Mexico's exports – and its appetite for crossovers and pickup trucks bolstered by cheap gas prices. While Mexico does build some light truck models – AN specifically calls out the Ram 2500, Honda HR-V, GMC Sierra, and Toyota Tacoma as export leaders – the vast majority of vehicles rolling out of its factories are sedans and hatchbacks. In fact, the three biggest drops in Mexican exports came from companies whose south of the border factories only build cars – Ford (Fusion/Lincoln MKZ and Fiesta), Mazda (Mazda3), and Volkswagen (Golf and Jetta). Mexican Automotive Industry Association President Eduardo Solis told AN the export shortfall will likely be sorted out sooner rather than later, thanks to a pair of new factories – a Kia car factory and an Audi SUV plant – that are coming online by year's end. The two facilities will add around 100,000 vehicles to the country's export totals, which Solis said should leave the industry on the verge of breaking another export record in 2016. But how sustainable will these record-breaking years be? Slapping an "Hecho en Mexico" sticker on a new German SUV won't be enough to change the fact that Mexico's product mix is tilted too heavily towards body styles that are not growing in volume. Mexico's record-breaking export years probably aren't at an end, but we'd argue they're certainly under threat.

Mazda boss says no to new-generation Mazda3 hot hatch

Mazda offered a hot, turbocharged version of the Mazda3 model during the car's first two generations, badging it either the MPS or the Mazdaspeed 3 depending on the market. The third generation car didn't get a hot-hatch variant, and now Mazda is saying there won't be one for the freshly revealed fourth-gen car, either. Mazda's new global boss, Akira Marumoto, told Australian motor journalists at the Los Angeles show that there won't be an MPS in the cards. As Drive quotes Marumoto: "Mazda is a small player, and if [you are asking whether] that segment has a high particular priority for Mazda, my answer would be no. Therefore we not planning for MPS in the future." Marumoto stated that Mazda would rather establish itself as a genuine premium carmaker comparable to its European rivals, stressing that this would be achievable through quality, comfort and refinement improvements in the existing lineup rather than expanding into other segments. As well as nixing the Mazda3 MPS, Marumoto also said that despite repeated queries, the function of the 2015 Tokyo Motor Show car RX Vision was to preview the evolution of the Kodo design language and not to herald the arrival of a new rotary sportscar. So, it's time to cue the Mazda Kills Rotary Sports Car Again headlines. Marumoto also told journalists that there won't be an EV sports car or a completely driverless car from Mazda either: He said he prefers the smell of gasoline to full electric power, and that Mazda will never build a car without a steering wheel. For Mazda, autonomous capabilities would serve to bring the car to a safe halt in the case of an incapacitated driver, instead of doing the driving. However — and there is a strong "however" — Mazda did tell us that the turbocharged 2.5-liter engine does fit into the new 3. Mazda representatives said that the header on the naturally aspirated version is big enough as it is, making it easy to shoehorn in the 250-horsepower turbo version without issue. They also said that the company is closely monitoring buyer demand, which originally led to the turbo being available on the Mazda6 and CX-5, along with justifying the introduction of all-wheel-drive in the new Mazda3. So: if there is a case for it, the turbo might come — just don't call it a Mazdaspeed 3, or view it as an overt hot hatch. But the shoe fits.
