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 Mazda2 gets EPA-rated 43 mpg highway

To paraphrase the famous quote from astronaut Neil Armstrong, that's one small step for man and one giant leap for the Mazda2. The Environmental Protection Agency (EPA) has weighed in on the new Mazda2 version, and says it gets a fuel-economy rating of 33 miles per gallon city and 43 mpg highway with a six-speed automatic transmission. Stick-shift gas-mileage figures are 31 city and 42 highway, which are still substantially better than the 29/35 rating from the most recent iteration of the model. That's about a 15-percent jump in fuel economy, people. More importantly, the Mazda2 beats out competitors such as the Hyundai Accent, Kia Rio Eco and even the Honda Fit in terms of fuel efficiency, which is pretty good company. The Mazda2 boasts a 1.5-liter four-cylinder engine. But it is the upgrade to six-speed transmissions in both manual and automatic versions that seem to be making the biggest difference in the ratings. Mazda started unveiling details about the next-generation Mazda2 last year, and last fall began production of the model at Mazda's new factory in Salamanca, Mexico. At that time, the Japanese automaker had already sold more than 2.4 million Mazda2 vehicles since the model's introduction in 1996. Related Video:

2014 Mazda6: Introduction

An Extended Stay With The Sexy Six
The new-for-2014 Mazda6 sedan is more than just a pretty face. For Mazda, it marks the company's best effort yet at competing in the highly competitive midsize sedan segment, all the while staying true to the brand's core value of offering high levels of driver involvement above all. We certainly came away impressed after our first drive of the sleek Six in France last fall, and we knew right from the start that this would be a car we'd want to spend a lot of time with back here at home.
So with that in mind, the folks at Mazda graciously agreed to loan us the fully loaded Soul Red tester you see here for a one-year stay in the Autoblog long-term garage. Because of how important this car is to the segment, and to Mazda as a brand, we know there's going to be a lot to talk about it over the next 12 months. Right now, though, allow us to introduce you to the newest member of our long-term family.
