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.

Mazda on sales upswing in Europe but won't build there

Auto sales in Europe have been a tricky proposition for some years, but Mazda has seen some success on the backs of the CX-5 and new Mazda6. According to a report form Automotive News Europe, though, that doesn't mean we should be looking for the Japanese manufacturer to set up production operations there.
Mazda's European CEO, Jeff Guyton, explained to AN that "Our intention is to have manufacturing scale. That gives you scale economy and quality through repeatability." In other words, a big honking plant in one part of the world is preferable to a half dozen small factories building the same vehicles.
European sales for Mazda are up 5.4 percent in the first half of 2013, with 74,000 units sold. That kicked the Zoom-Zoom brand's market share up from one to 1.2 percent. Small gains, but gains nonetheless. According to Guyton, Mazda would need to sell 200,000 units of just one model in Europe for local production to make sense. Mazda's best European year saw 320,000 units sold across the entire range.

Mazda says 83 percent of new cars bear Skyactiv moniker

Mazda's US sales are down a little bit but the company's fuel economy is almost assuredly up. That's because its fuel-saving Skyactiv drivetrain technology is essentially taking over US vehicles sales. To the tune of about five out of every six vehicles sold, at least. While the Japanese automaker's US sales in February fell 2.4 percent from a year earlier, Skyactiv accounted for 83 percent of its sales last month. Most notably, Mazda6 sales jumped 46 percent from a year earlier, while Mazda CX-5 sales were up 72 percent. The company also celebrated the opening of its factory in Salamanca, Mexico, where it will make models such as the Mazda2 and Mazda3. The company is not resting on its fuel-economy laurels either, apparently. In January, it was reported the company is hard at work on its next-generation Skyactiv technology, which will boost fuel efficiency by as much as 30 percent by using diesel-like high compression. As it is, Mazda had the highest fleetwide fuel economy of any major automaker in the US for the 2013 model year with a 27.5 mile per gallon average, according to the Environmental Protection Agency (EPA). Honda came in second with 27 mpg. Check out Mazda's press release below. MAZDA SKYACTIV® TECHNOLOGY SETS RECORDS IN FEBRUARY - Mazda Celebrates Grand Opening of All-New Production Facility in Salamanca, Mexico - IRVINE, Calif., March 3, 2014 /PRNewswire/ -- Mazda North American Operations (MNAO) today reported February U.S. sales of 24,431 vehicles, representing a decrease of 2.4 percent versus last year. Year-to-date sales through February are down 6.7 percent versus last year, with 43,155 vehicles sold. Key February sales notes: Mazda's SKYACTIV® TECHNOLOGY accounted for 83.2 percent of all vehicle sales during the month of February. This is the largest percentage of Mazdas equipped with SKYACTIV TECHNOLOGY sold in one month, and second-best month of total volume ever with 20,245 vehicles sold. Mazda6 experienced its second-best February since 2008 with 3,945 vehicles sold, representing an increase of 46.0 percent, year-over-year (YOY). February 2014 was CX-5's best month ever with 9,353 vehicles sold, good for an increase of 71.6 percent, YOY. February was one of the most historic months for Mazda as it celebrated the grand opening of its all-new engine and vehicle assembly plant in Salamanca, Mexico.
