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.

eBay Find of the Day: 1990 Mazda Miata with just 27 original miles

Some cars have low mileage, and others have close to no miles at all. This 1990 Mazda Miata, currently listed on eBay Motors and located in Kingman, Arizona, falls into the latter category with only 27 miles on the odometer, according to the seller. But we have to wonder: how did one of the best-driving, most influential sports cars of the past two decades sit without being driven for 24 years? Consider it the seller's loss on this one.
The seller says he bought the car with 20 miles on it, and explains 6.9 miles were added when the car was towed home on a car dolly. It was never registered. Furthermore, the seller says the car didn't come with a set of keys, so he had to have a set made. Though the paint is clean and shiny, the Miata didn't escape minor cosmetic damage over the years, with scratches on the hood, the trunk and the factory hardtop that is included with the car. The front, right fender has a small dent as well, which can be seen in a picture. The seller says the car was stored in a building with windows, so the paint is faded a bit in some places. It's missing its antenna and the battery, and the only non-original parts on the car are the windshield wipers. The clear-title car comes with all paperwork, according to the seller, but, besides the owners manual, he didn't specify what other documentation would be included.
With bidding currently at $10,300 and the reserve not met, this Miata definitely isn't the deal of the century, and we have to question where the value is in this one. The way we see it, it's hard to justify the money if it can't be driven as-is (come on, no battery?), has questionable history, isn't rare and sat in storage for its whole existence. The "weather cracked" tires are probably just the first rubber parts on the car that need to be replaced before it can be driven, but at least the spark plugs were removed and the cylinders were filled with Marvel Mystery Oil prior to storage, which helps to prevent rust and corrosion from forming in the engine.

Mazda6 Skyactiv-D racecar gets first win at Road Atlanta

Mazda has a long motorsports history, and one that is peppered with fascinating cars. The latest chapter in Mazda's racing story has just been written, as Joel Miller and Andrew Carbonell have driven the Visit Florida Racing Mazda6 Skyactiv-D to the car's first ever victory at the Rolex Grand-Am GX race at Road Atlanta. The win marks the first ever for Mazda's diesel-burning, production-car based Skyactiv-D racer, and the first win for a diesel-powered car in a Grand-Am event.
In fact, it was a particularly good day for the Mazda Motorsports team, as a Mazda6 also picked up the third finishing spot at Road Atlanta. Director of Mazda Motorsports, John M. Doonan, said of the racecar, "We've always said that the best street cars make the best racecars, and, with more than half of the components in the race engine being shared with the street engine, this program is a solid proof-point."
SpeedSource Engineering, which helped to build the Mazda6 racer, was greatly heartened by the car's performance in just it's fourth-ever race. Owner Sylvain Tremblay called the victory, "a tribute to the thousands of hours of hard work over many months," continuing, "The normal plan with a new car is to spend the first year in development, the second year seeking race wins, and challenging for a championship in year three. We are already at our year-two status after four races. We can't wait to get to the Belle Isle course in Detroit for round five."
