The Quaife differential powers both drive wheels under nearly all conditions, instead of just one. With an ordinary open differential (standard on most cars), a lot of precious power is wasted during wheel spin under acceleration. This happens because the open differential shifts power to the wheel with less grip along the path of least resistance. The Quaife, however, does just the opposite. It senses which wheel has the better grip and biases the power to that wheel. It does this smoothly and constantly, and without ever completely removing power from the other wheel. In drag race-style, straight-line acceleration runs, this results in a close to ideal 50 / 50 power split to both drive wheels, resulting in essentially twice the grip of an ordinary differential. They don't call open differentials "peglegs" for nothing.

In cornering while accelerating out of a turn, the Quaife biases power to the outside wheel, reducing inside wheel spin. This allows the driver to begin accelerating earlier, exiting the corner at a higher speed.
