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.

Toyota, Mazda partner to build EVs at new $1.6 billion U.S. plant

TOKYO — Toyota and Mazda plan to build a $1.6 billion U.S. assembly plant, the two said on Friday, as part of an alliance that will also see the Japanese automakers jointly develop electric vehicle technologies. The two will take small stakes in each other as part of the tie-up: Toyota, the world's second-largest automaker by vehicle sales last year, will take a 5 percent share of Mazda, extending its dominance in Japan's auto sector. Mazda will take a 0.25 percent share of its larger rival. The plant, something of a surprise at a time of overcapacity in the U.S. market, will be a boost to U.S. President Donald Trump, who campaigned on promises to increase manufacturing and expand employment for American autoworkers. The plant will be capable of producing 300,000 vehicles a year, with production divided between the two automakers, and employ about 4,000 people. It will start operating in 2021. The electric vehicles cooperation, meanwhile, comes as the tightening of global emissions regulations prompts more automakers to develop battery powered cars, as the industry struggles with hefty research costs and intense competition from technology companies over technology like self-driving cars. As part of the agreement, Toyota and Mazda will also work together to develop in-car information technologies and automated driving functions. Toyota, Japan's biggest auto company, has been forging alliances with smaller Japanese rivals for several years, effectively engineering a loose consolidation of the Japanese auto sector. It already owns a 16.5 percent stake in Subaru, Japan's No. 6 automaker, with which it also has a development partnership. Toyota is also courting compact car maker Suzuki to cooperate on R&D and parts supply as Toyota seeks to tap its smaller rival's expertise in emerging Asian markets. A stake in Mazda may also prevent future incursions by tech companies, one analyst said. "For a technology company which lacks the expertise in making cars, Mazda could look like a very interesting acquisition. They're very good, they're not too expensive. Maybe Toyota realizes this," CLSA managing director Chris Richter said. "By buying a 5 percent stake, Toyota takes Mazda off the table rather than having it sit out there like a free agent which could someday be used against them." COROLLA PRODUCTION SHIFT Mazda stands to gain from a deal that gives the small automaker a production foothold in the United States.

Better as a coupe | 2017 Mazda MX-5 Miata RF First Drive

The sun can kill you. It'll also make you hot and sticky and smelly. It's a real nasty thing despite, you know, making virtually all life on Earth possible. Now, apparently, despite these risks, there are those who enjoy driving around in their car being slowly baked alive by our local star. It's insanity, really, and that's not even mentioning the indignities your hair suffers at the merciless force of the wind. So convertibles, then, who needs 'em? Just take the Mazda MX-5 Miata. Wonderful little car, barrels of fun, but wouldn't it be better off with 100 percent less sun? Besides keeping your dermatologist out of business, a solid roof would also lead to less wind noise, greater structural rigidity, and better safety for the vampire population. Nothing but Ws on the board. Alas, the 2017 Mazda MX-5 Miata RF is not the ideal solution to this perfectly sane line of reasoning. It is not the BMW M Coupe or Porsche Cayman of Miatas. It's more like the 911 Targa of Miatas, although since its rear window lowers, the most accurate analogy would be the Honda Civic del Sol of Miatas. Feel free to put that on a billboard. Admittedly, it's a pretty neat bit of engineering and design, and despite the incredibly flattering comparison above, it is accurate to describe its overall look and concept as unique. RF stands for "Retractable Fastback," which is an on-the-nose description. With the entire roof mechanism in place, it does indeed resemble a fastback in profile. From a rear-three-quarter view, that fastback is revealed instead to be buttress panels with a longer deck and a verticalish window placed between them. The Ferrari 575M Superamerica would be another point of reference, but the Miata RF is far better realized. It's particularly impressive how Mazda's designers managed to carefully reshape the Miata's rear quarters to fit and conceal the buttresses' cut line. From most angles, there's no indication that they're anything other than contiguous with the rest of the car. The little black panels that look like darkened windows at first glance are less successful, but they're also clearly necessary to create the desired buttress look and to conceal the roof mechanicals beyond. Ah yes, the compact mechanicals that make the fastback retractable and subject you to the sun's wrath.
