Eerily peaceful is what the Mazda 3 felt like through the slalom. At constant throttle without lifting for the next cone, GVC Plus worked surprisingly well to accentuate grip and subdue understeer.
The actual application is very subtle but it’s there. Also sounds like black magic whenever someone tries to explain how GVC works. The only thing you need to know about GVC is it helps the car corner better by automatically cutting power at turn-in, to induce frontal grip and even continues regulating power throughout the corner to retain a consistent lateral G for maximum uninterruptedness.
GVC is created to manage bad driving basically. It takes the effort away from the driver and he / she will have no clue it is working in the background, perpetually monitoring steering input and intercepts instantly, ever so gently to reduce spikes in G forces especially at the corners.
The latest GVC Plus in the Mazda 3 adds on braking, for the purpose of stabilising the car in between direction changes or when steering away from an obstacle. This is done by gently braking the outer wheels as the steering returns to center position.
