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.

Mazda2 sedan debuting in Thailand this month?

Mazda is reportedly set to introduce a Mazda2 with a four-door sedan body. Unlike the upcoming CX-3, which is debuting at the upcoming Los Angeles Auto Show and is almost certain to be sold in North America, this other version's chance here are a bit more mysterious.
According to The Bangkok Post, the Mazda2 sedan will make its word debut at the Thailand International Motor Expo on November 28, and the traditional five-door hatch will be there as well. Both body styles will be built in Thailand with diesel engines and will be the first vehicles to adhere to the country's eco-car rules for oil-burners with a SkyActiv 1.5-liter diesel that will make 105 horsepower.
At this time, there's no indication whether the new sedan might also be sold in the US, but we're not holding our breath - remember, the previous Mazda2 sedan never made it Stateside, either.

Mazda MX-5 GT gets green light

The Mazda MX-5 Miata is as popular around the Autoblog offices as Kate Upton posters are around fraternity houses. Few staffers have much criticism for Mazda's ubiquitous roadster, and fewer still aren't overjoyed when one arrives in their driveway. So you can imagine how a report from Auto Express about a more potent MX-5 model is going over in our offices today.
The new model, which was shown in concept form as the Mazda MX-5 GT at the Goodwood Festival of Speed, has a slight catch, though. First, we have absolutely no idea if Mazda will bring the MX-5 GT to the US. Secondly, and perhaps more problematically, this isn't a production car - it's a kit from the team at Jota Sport.
Now, to be fair, the kit doesn't sound like a bad thing. It bumps the UK-spec 2.0-liter, 157-horsepower engine up to 203 hp thanks to a sports exhaust and a revamped ECU (46 horsepower from an ECU and exhaust in a naturally aspirated car?). To make the little Miata even more agile, Jota has also fiddled with the suspension. AE doesn't mention things like the grippy tires or Recaro seats that were found on the concept, though.
