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 returning to top-tier racing with diesel-powered prototype in USCC

Mazda has unveiled its latest challenger in the top flight of endurance racing, a diesel-powered prototype that will campaign the inaugural, 2014 Tudor United SportsCar Championship. The new Skyactiv-D-powered car will make its race debut at January's Rolex 24 at Daytona.
"This is the most significant step Mazda has taken towards returning to the global racing stage since our overall victory at Le Mans in 1991," said the director of Mazda Motorsports, John Doonan. That historic racecar, the rotary-powered 787B, has grown to become one of Mazda's many, well-known racers.
More recently, the Japanese brand has been making waves in the Grand-Am series, campaigning RX-8s and, most recently, running diesel-powered Mazda6 sedans in the GX-class. Mazda will campaign two factory-backed prototypes at Daytona. Driver lineups will be announced closer to race day.

Mazda spiders return, 42k Mazda6 sedans recalled for webby fuel tanks

It seems that Yellow Sac spiders really, really love Mazda. Three years after Mazda recalled 52,000 Mazda6 sedans over spider webs obstructing the evaporative canister vent lines of 2009 and 2010 Mazda6 models, another recall has been issued for 42,000 more of the models built between 2010 and 2012 and equipped with the 2.5-liter four-cylinder engine.
According to the automaker, there have been nine confirmed sightings of spiders in vent lines since the original recall. It seems that covers were applied at the factory to keep the arachnids from entering, but it hasn't quite exterminated the problem. A reflash of the ECU is required that "[changes] the logic behind how the car purges the charcoal canister during normal operation," says Jeremy Barnes, Director, Public Relations & Brand Experience at Mazda North American Operations.
So far, Mazda has not recorded any fires, accidents or injuries due to this tangled mess of webs. Recall notices will be mailed out to owners later this month.
