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.

Mazda6 diesel engine delayed over low performance, still coming

Oh Mazda... we had many hopes for the promised diesel four-cylinder in the Mazda6, but those have remained largely unfulfilled, as the oil-burning powerplant has failed to appear on dealer lots following its 2012 LA Auto Show announcement. Despite engineering issues that forced the company to announce that the program was delayed back in September 2013, Mazda remains adamant that the 2.2-liter Skyactiv-D is still coming to our shores. "We're still very much committed to diesel," Mazda's North American CEO, Jim O'Sullivan, told Automotive News. "We are still working on getting the performance aspects up to where we want them, and we do have a plan – an engineering road map – to get it done." According to AN, Mazda's initial plan with the 2.2-liter diesel was to build an engine so clean it could get by without an aftertreatment system, which generally accounts for the price premium of diesel engines versus their gas counterparts. The new system has come with performance issues, though, necessitating the delays. "If [we were] a commodity brand and didn't care about that, it would be on the market right now," O'Sullivan told AN. "But I know the people were expecting something from us, expecting certain drive characteristics and performance, and I didn't want to disappoint them." While O'Sullivan's defense of the diesel Mazda is admirable, the exec stops short of giving us an indication of when the new engine will finally arrive.

Mazda sketches Koeru concept ahead of Frankfurt show

Mazda is giving us an early peek at the Koeru concept set to debut at the Frankfurt motor show. With a name derived from the Japanese word for "exceed" or "go beyond," the model is the latest evolution in the company's long-lived Kodo design language. Sketches tend to distort a vehicle's actual proportions, and the perspective on this one appears to be playing some visual tricks. Some things can't be hidden so easily, though. The Koeru appears to wear a more sharply angled version of Mazda's shield-shaped grille, and the headlights evolve the look of the CX-3 with an even narrower squint. The steeply raked rear hatch provides a coupe-like roofline, but we wonder if the angle is this pronounced in real life. Reports from last year suggest that a new CX-9 is on the way in 2016, and we could be getting a preview with the Koeru. Mazda is also purportedly developing a CX-7 successor. We should get a better idea if this show car represents either of those future CUVs when we can see it in the metal in Germany. MAZDA TO UNVEIL NEW CROSSOVER CONCEPT IN FRANKFURT Mazda Koeru features a distinctly powerful rendition of the KODO design theme Japanese carmaker aims to further raise benchmark in competitive SUV segment Hiroshima / Leverkusen, 7 August 2015. In a world premiere at the 66th 2015 Frankfurt International Motor Show (IAA), Mazda will reveal the Mazda Koeru, a new crossover SUV concept that makes a bold statement in an increasingly popular and competitive segment. Koeru, Japanese for "exceed" or "go beyond", is a fitting name for Mazda's latest venture into the growing crossover SUV market, where the company is again looking to surpass existing standards and raise the bar for performance, efficiency and overall value. With its formidable KODO – Soul of Motion design, the Koeru expresses the power and vitality of a predator along with a unique level of refined dignity. The full line-up of Mazda's latest SKYACTIV Technology, meanwhile, ensures outstanding dynamic performance, fuel economy and safety with no compromise to Mazda's patented driving fun. The carmaker will also display its new-generation model line-up in Frankfurt. Highlights include an all-new Mazda MX-5 complete with accessories as well as several SKYACTIV powertrains. Mazda's press conference takes place at 13:45 (hall 9.0, B16) on 15 September, the first of two press days. The IAA is open to the public from 17-27 September.
