I love driving the M3 hard on the curves, thanks to G-Vectoring Control!
Behind the Science: How G-Vectoring Control Gives the Mazda3 a Dynamic Edge
To understand the role of G-Vectoring Control, imagine any ordinary driving situation where you’re coming into a corner. In most cars, you point the wheels in the direction of travel, and not much else happens. If necessary, traction control will kick in to help you keep from flying off the road. Minor steering or braking corrections are often necessary to achieve the right path through the corner.
But in the Mazda3 equipped with GVC, every time you turn the steering wheel, whether to full lock or just a tiny bit, the system instantaneously cuts a bit of engine torque to help the car glide smoothly through the corner. It’s a minor incision with significant impact. It’s neither a full-on intrusion, like stability control, nor torque vectoring, which shifts power among the wheels. And it’s almost a given that you won’t feel GVC at work. As the steering wheel moves, GVC monitors the amount of force and steps in accordingly, as if to say, “Let me help you out here.” In turn, the front wheels gain additional grip, and the result is a straighter line through the corner with fewer steering adjustments needed to make it happen.
By now, you might be wondering why a machine like the Mazda3 would need any additional enhancement to its driving dynamics. For the answer, all you need to do is refer to Mazda’s cardinal rule of jinba-ittai: human and machine moving as one. Mazda seems to care more than most car companies about drivers being able to revel in the pleasure of driving. Remember, the substance of GVC is software, not hardware. Computers are making it all happen. From the company that emphasizes and expounds on the manual pleasures of driving, this is a big deal.
In testing, it’s difficult to feel the system at work. We can’t think of higher praise for a driver aid than that. GVC doesn’t change the steering feel, but it intensifies the feeling of stability, making it easier to feel your way through a corner. It also helps with straight-line stability, thanks to sensors that mitigate steering correction. Perhaps most important, GVC also lessens the feeling of being buffeted around by the car. Having to make fewer corrections reduces driver fatigue and increases driver comfort. In short, the Mazda3 equipped with G-Vectoring Control provides more feel with less necessary input.
