    I am trying to figure out (based on a thread over at the Tesla forums) what ESC is. It's listed as a separate item from Traction Control on the Tesla Model X specifications page. Yet in the Owner's Manual, the entry for Stability Control in the index takes you to the page for Traction Control. So... is there a separate stability control, and what does it exactly do?

    My other thought is that maybe they mean how the air suspension will try to keep the car level.

    Generally, Traction Control only refers to the feature where torque is cut dramatically to prevent wheelspin. ESC is a complex 6-axis model of the movement of your car which tracks all your car's motions with an accelerometer and gyroscope and monitors for oversteer, understeer, left-right traction imbalance and so on.

    However, it's very likely on modern cars both functions are provided by the same piece of hardware so the terms are somewhat interchangeable.

    Right. The description you gave is what I'd expect Stability Control to be. Just odd that they don't specify more about what it does or how it works anywhere.

    I can speak from personal experience, the X does have both traction control AND stability control. T/C will prevent wheel slip when accelerating, stability control will help keep the car under control in situations causing it to slide or fish tail. They both work quite well.

    Well given that there's no way to defeat ESC and only a slight way of influencing Traction Control (slip start), I don't blame Tesla for not wanting to talk more about it.

    I find that most manufacturers' wording of the ESC feature makes it sound like the car has supernatural abilities and coaxes drivers into driving dangerously.
