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.

2019 Mazda CX-3 small crossover will start at $21,365

The figures are in for the 2019 Mazda CX-3 subcompact crossover, which will start at $21,365 when it arrives in showrooms later this month. That's $280 above the outgoing model, including a $975 destination and handling fee. Fuel economy figures are also now in from the EPA. When equipped with front-wheel drive, the 2019 CX-3 gets 29 miles per gallon in the city and 34 on the highway for a combined 31 mpg. The all-wheel-drive version is rated at 27 mpg in the city, 32 on the highway and 29 combined. Which are ... exactly the same figures as the outgoing version (so much for the promised fuel economy improvements). We detailed most of what's new about the 2019 version back in March at the New York Auto Show. Mostly, they're non-cosmetic changes: The carryover 2.0-liter Skyactiv four-cylinder picks up a couple more horsepower and pound-feet of torque for 148 total horsepower and 146 pound-feet of torque, joining a six-speed automatic transmission with manual-shift and sport modes. It also gets Mazda's G-Vectoring Control driving technology, a sportier, retuned suspension and improvements to make the driving experience quieter and more refined. Mazda says it's also added an electronic parking brake, which necessitated a redesign of the center console and armrest, adding storage space, and it redesigned the front seats and added a new rear armrest with built-in cupholders. Standard features include a new direct tire-pressure monitoring system and blind-spot monitoring with rear cross-traffic alert, two USB ports, a rearview camera, hands-free Bluetooth calling and audio pairing capability, and the 7-inch Mazda Connect full-color infotainment and diagnostic display, controllable via voice command or control knob. The new Sport i-ACTIVSENSE Package of safety technologies is available for an extra $1,100. It adds features including smart city braking support with pedestrian detection, lane departure warning, radar cruise control with stop-and-go function, LED headlights and LED combination tail lights. Other trim levels include Touring, which adds 18-inch wheels and keyless entry, and the top-level Grand Touring, which starts at $26,720 and $28,120 for front- and all-wheel-drive configurations, respectively. Grand Touring includes the Sport i-ACTIVSENSE Package, plus Parchment or black full-leather seating with high-gloss pleated piping and chrome accents on the front bumper and side sills, among other features.

Dealers think Mazda's new Mexico plant will increase Mazda3 sales by 20%

Mazda3 sales in the US were down about 15 percent last year to a total of 104,713 units. According to a report from Automotive News, though, the slowdown in sales has been due more to production constraints than demand.
Good news for Mazda dealers, then, that a new plant in Salamanca, Mexico has just come online. Tom Carey, chairman of Mazda's national dealer council, told AN, "We're going to be in good shape because of that Mexico inventory." If estimates prove accurate, sales of the Mazda3 will increase by about 20 percent when the new plant begins production this month.
If those lofty projections come to pass, Mazda will reportedly be on track to exceed 300,000 total sales in the US in 2014, which would represent the brand's highest figures since its 375,000-unit peak in 1994. The brand hopes to sell more than 400,000 vehicles in the US by 2016, and with well-received products like the latest 3 and Mazda6 sedan, such expectations seem quite possible.
