Mazda G-Vectoring Control

Ben Hsu, writing for Autoblog:

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.

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. We suspect most drivers will notice the latter most starkly. The wet stretch was designed so that the tires were just on the brink of losing traction with G-Vectoring off. At the same speed when switched on, the extra grip kept the car planted through that section.

It's always great to hear a mainstream, non-premium car manufacturer introduce an innovative, software based safety measure. Although G-Vectoring Control will not have any significant effect most of the time, initiatives such as this are the best kind of safety measure- always active, but unnoticeable unless required.
