    On earlier HCHs and Insight I and II, that's the case. There's no electric AC compressor. Same deal w/NHW11.

    IIRC, HCH-II added the electric AC compressor so that the ICE can shutdown at stoplights w/AC on.

    What Cwernda said. I believe the HCH-II allows the compressor to be belt-driven or electrically driven.

    It will kick in the moment you lift off the brake pedal which is a little annoying when making left turns.

    Its been a while but it is nice to see the discussion is still alive and well. ;)

    Well, back to my usual routine... and yes, for those who still remember me, I will be "upgrading" my current 2006 HCH to the newer 2012 as soon as it is released in Canada.

    Also as a friendly reminder: The electric stator/motor in current IMA designs was not developed to produce HP numbers. Its design (high energy density) was purposely engineered to provide a meaningful boost in torque numbers when the ICE is weakest.
    For instance, on the current HCH-II the electric motor provides the equivalent of just 20HP but it produces almost as much torque at just 1000RPM as the ICE produces at 6000 RPM.

    Cheers

    The "electric compressor" can be operated under full duty and without stopping depending on how you set the climate control. The compressor starts in electric and the belt driven half is triggered on if the cooling demands are too high. Again, both can work exclusively or in tandem as required by the system.

    Hummm... after having driven dozens of HCH-II's and owning a couple I must say I have not noticed the issue with "left turns" yet. ;)

    Cheers

    I'll reserve judgement until I see how many units sell. While some may criticize Honda for not making the Civic as efficient as the Prius, I would consider the new Civic a success if it got more people out of a gas guzzler and into a 40+mpg vehicle.

    Ahh I see. Well I thought that the HCH-II's system might be good as it runs off the engine while the engine is running and off the HV battery when it's off. It still puts a drag on the engine but I figured it's more efficient than if the engine had to charge the battery.

    Well I just remember that left turn I did on the test drive. Had to creep a few times. Maybe it was because the car was new and hasn't broken in yet.

    Looking forward to your report on the HCH-III.

    If AC is running AutoStop will tend to pack it in sooner, re-start the engine: the state of charge runs down quicker.
