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.

This is the 2017 Mazda MX-5 RF targa-roof fastback

We knew Mazda was going to introduce a new Miata variant ahead of the 2016 New York International Auto Show, but the smart money was on a power retractable hardtop version that largely mirrored the last-gen car's folding number. So it was a surprise when the new 2017 Mazda MX-5 RF – retractable fastback – drove onto the stage sporting wild buttresses and a hide-away targa roof panel. The buttresses lift up and swallow the rear window and roof panel in a matter of seconds, and then the buttresses snug back down. This leaves a hoop spanning the buttresses, but at least it's done up in black to be less visually apparent. The result is more of a targa roof experience, rather than the previous PRHT which gave occupants essentially the same experience as the soft-top with the top down. No matter. The result is stunning, and will differentiate the RF even more from the standard MX-5. Mazda designers took extra care to make sure the interface between the MX-5's dramatic fenders and the trailing edges of the roof support provided enough visual drama. Mission accomplished, we'd say. We can't take our eyes off that part of the car. View 13 Photos As you might expect, mechanical changes seem to be minor, although we'll be asking for detailed specs. Both the 1.5- and 2.0-liter engines will be available globally, but only the 2.0-liter Skyactiv-G engine will be sold in the US. The roof can be operated at up to 6.2 mph. Mazda claims the truck space is unaltered from the soft-top model. We don't yet know how much, if any, the RF's mechanism adds to the bantamweight roadster, nor the premium it'll command. Expect those details closer to launch. Related Video:

'Gran Turismo Sport' Super Bundle comes with a real Mazda Miata

"Gran Turismo Sport" is now on sale (stay tuned for a full review in the near future), and as with most video games now, there are basic versions and those that come with a few extras. For instance, in the United States there's a Limited Edition version that includes the full game, plus a metal box, several Group B rally cars and a couple of prototype cars unlocked, as well as 1,000,000 credits available at the start. It's a pretty meager special edition compared with the "Gran Turismo Sport" Super Bundle on offer in Taiwan, though. The Super Bundle lives up to its name primarily because it comes with a real, drivable Mazda MX-5 Miata. It comes in Soul Red and features custom Gran Turismo vinyl graphics. On top of that, the bundle comes with a Bravia 4K HDR OLED TV, a Playstation 4 Pro, Playstation VR, a year of Playstation Plus (the online multiplayer service), a Thrustmaster T-GT steering wheel controller, and an Apiga AP1 racing seat for playing the game. Oh, and of course it comes with a copy of the game. Funny enough, this isn't the first time a car has been offered as part of a video game bundle. When " Grid 2" launched a few years ago, the developer, Codemasters, partnered with BAC to sell a Mono edition. This special edition of the game came with a real life BAC Mono with "Grid 2" livery. There's no such thing as a free lunch, or a free car for that matter. At current exchange rates, the " Gran Turismo Sport" Super Bundle costs just shy of $46,300. Now that's a much more affordable proposition than the " Grid 2" BAC Mono package, which rang in at about $189,000, though the Miata is a much more affordable car with less performance. Americans shouldn't be disappointed the " Gran Turismo Sport" Super Bundle isn't available here, though. This is because the Super Bundle can be re-created here for much less money. Every item in the bundle plus a Miata Sport with a manual transmission and the Soul Red paint would come to a little under $32,000, a savings of over $14,000.
