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 to race at Rolex 24, team and drivers announced

Mazda is getting serious about showing off the Skyactiv-D turbo-diesel four-cylinder engine in the Mazda6. The automaker has just announced it will campaign three diesel Mazda6 racers in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona in a quest to walk away with the company's 24th class win. Mazda partnered with SpeedSource to develop the race version of the new sedan, with Japanese and American engineers lending a helping hand where needed. Meanwhile, Freedom Autosport and Visit Florida Racing/SpeedSource/Yellow Dragon Racing will helm teams of their own.
Each car will make use of a five-driver team for the 24-hour race on January 26. In the interim, you can check out the full press release below for more information as well as the full driver roster. Mazda says we can expect to see the No. 70 SpeedSource car under the lights at the 2013 Detroit Auto Show later this month, as well.

The Mazda MX-5 Miata RF's trick roof will cost you at least $2,555 extra

Now that loyal customers have been given the opportunity to preorder the Mazda MX-5 Miata RF Launch Edition, Mazda has finally announced pricing for the regular 2017 MX-5 RF lineup. The vehicle, with its gorgeous power retractable hardtop, will come in two trims – the MX-5 RF Club and Grand Touring when the vehicle goes on sale early next year. The MX-5 RF Club with the manual transmission is priced at $32,390, including $835 destination, which represents an additional $2,955 over a six-speed manual MX-5 Club with a soft top. An automatic is a $730 option for both RF and soft top Club models. The range-topping MX-5 RF Grand Touring trim will start at $33,455 with a six-speed manual transmission, which is $1,170 less than the Launch Edition's price tag of $34,685 and $2,555 more than a soft-top model. Opting for the automatic transmission on the Grand Touring trim bumps the price tag up to $34,660. The MX-5 RF models are similarly equipped to the soft-top models. The Club models benefit from cloth seats with red stitching, a limited-slip differential (when equipped with a manual transmission), suspension from Bilstein, and an optional Brembo brake and BBS wheel package for an extra $3,400. The more luxurious Grand Touring models get adaptive headlights, heated leather seats, and lane departure warning. The MX-5 RF models, just like the regular soft-top models, don't have many options. Hands-free keyless entry is a $130 option, while premium paint options, which includes Machine Gray Metallic (the same color on the Launch Edition) and Soul Red Metallic both cost $300. Crystal White Pearl Mica is only available on Grand Touring models and will cost an additional $200. Unlike the Launch Edition that was limited to only 1,000 units, there's no production limit on the regular MX-5 RF. Mazda will being delivering the MX-5 RF Launch Edition in February of 2017, with the standard MX-5 RF models following shortly after.
