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.

Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

It's not exactly a Tesla Model S taking on a Ferrari, but for us green enthusiasts, a drag race and comparison between reasonably priced diesel hatchbacks does hold interest, and UK's Auto Express was kind enough to do the deed. When raced, the diesels actually laid a little rubber coming off the line, though the track was covered in rain. Did we mention it was in the UK? The comparison was between diesel hatchbacks priced at less than 22,000 British pounds (about $34,500 US), and Auto Express pitted a Mazda3, a BMW 1-Series and an Audi A3 against each other. The results are revealed in the 11-minute video you can watch below. In short, one car smoked the others. In order to set the tone, you should know that the Mazda's 150 horsepower is about 35 more than the other two entrants. The Mazda also earned points for its quiet motor (it sounds more like a petrol engine, the host says), standard equipment that would add about $4,000 to the other two cars if included and relative roominess in front and in back. The Audi gained points for its storage space, while the BMW had the only rear-wheel-drive car in the hunt. See for yourself how the competition stacks up.

Mazda recalls 2016-2018 Mazda3s for faulty windshield wipers

As the waves of rain showers continue to roll across the United States, Mazda has issued a recall related to a car's most important springtime feature: windshield wipers. Due to a faulty relay, the wipers on some 2016-2018 Mazda Mazda3s might stop functioning. The recall potentially affects 187,798 cars. According to NHTSA recall No. 19V272000, some 2016-2018 Mazda3s might have a malfunctioning windshield wiper relay within the front body control module that causes the wipers to become inoperable. As a resolution, Mazda will replace the old modules with new ones that have an "improved wiper relay design." This can be done at Mazda dealerships for free. This is not the first time the 2016 Mazda3 has been in the news for a recall. Although previous faults have been on smaller scales, the model previously had issues with a fuel shutoff valve causing a fuel leak, a deformed fuel tank causing a fuel leak, an improper weld on the fuel tank recirculation pipe causing a leak, and corroded parking brake actuators. Mazda has set June 3, 2019, as the expected recall start date, and owners may call Mazda customer service at 1-800-222-5500 to check on the status. The Mazda recall reference number is 3219D.
