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.

2016 Mazda MX-5 Miata in motion for the first time

By now, you've already poured over the details (however few there may be) and images of the 2016 Mazda MX-5 Miata. For us enthusiasts, it's arguably the most important new car debut of the year, and for Mazda, it marks the 25th anniversary of its iconic roadster - something that's being celebrated all weekend long out in Monterey, CA.
Our resident Miata owner, Chris Paukert, is out in sunny California and just passed along this video, showing all four generations of the MX-5 in motion (slowly), on the road at Mazda Raceway Laguna Seca. This is the first time the 2016 MX-5 has been shown driving under its own power, and it will join a wealth of other roadsters as Mazda attempts to break the world record for most Miatas in one place at one time.
Have a look at the emailed-from-an-iPhone-quality video above, and then take a moment to read Paukert's own notes from the ND Miata's live showing earlier this week, here.

Mazda3 with Skyactiv-X engine technology caught testing in the wild

Sometimes, automakers are fine with their mules coming under the watchful lenses of spy shooters. Proof of this can be seen plastered across the bodysides of the Mazda3 mule you see above. Clearly, Mazda wants the world to know that engineers are working hard on the company's so-called Skyactiv-X engine technology so badly that it's created a custom matte black vinyl wrap for its test mules. Clever. Expect to see this sweet new engine tech in the 2019 Mazda3. This SCCI, or Spark Controlled Compression Ignition system holds tremendous potential to boost the efficiency of gasoline-powered engines by 20-30 percent, thereby matching the fuel economy of a comparatively sized diesel engine. As an added bonus, torque figures are expected to jump a similar amount. Besides the placard-sized stickers, there isn't much to see here. The car is clearly a Mazda3 hatchback, though the fenders are punched out a bit and the fuel door is modified from stock. We'd wager that future prototypes will wear a lot more camouflage to cover up next-gen bodywork. In other words, stay tuned.
