    I would like to know more about the ION's ABS and traction control. Any
    takers? Thanks.

  2. The ABS on the Ion is a Bosch 8.0 ABS system. The traction control is a
    fairly simple system, it will signal the ECM to reduce engine torque output
    by retarding spark timing and/or cutting fuel delivery, and in some cases
    request the transmission upshift, when wheelspin is detected. It will not
    apply the brakes to stop wheelspin, as in some systems.

    I haven't seen the ABS on mine in action yet, we'll see this winter.
    However, that Bosch system seems fairly advanced, so it should hopefully
    work pretty well (better than the cheap Delco ABS VI system on many older GM

  3. It's a full four-channel system. (The main components in the hydraulic
    module are a pump, accumulator, and one inlet solenoid valve and one outlet
    solenoid valve for each wheel.)

    It also uses the ABS system to control the rear brake pressure (Dynamic Rear
    Proportioning) instead of a traditional mechanical proportioning valve.
