Do you folks realize that to run an A/C compressor on electric means that the ICE will run more often to recharge the battery to replace the energy that is being used to run the compressor. There is no "free lunch" - the energy has to come from somewhere.
I quote from a posting on "Green Hybrids.com":
"Ford engineers are smart people.
IF an electric A/C were an advantage, and the advantage out-weighed the cost, then it would have been included. I do not like it when people think they are smarter than a whole team of engineers.
The FEH is the way it is, because it is the BEST way to do things, for the majority of users, in the majority of situations, in the majority of climates.
YOU may be an exception, in the minority, and it may not be best for you.
But if you look at the whole fleet, world-wide, then an ICE based A/C is the best answer, and has the lowest environmental impact to the planet. And isn't that what you really want?
Isn't it better for you to burn an extra ounce of gas at a stoplight to run the A/C a couple months a year, than for 9 others to burn 9 extra ounces of gas to re-charge the battery from using an electrical A/C? ( Plus what if an electrical A/C meant you got a 6 year battery warranty??? Still want it? )
Remember, the A/C in your HOME is the largest power user you own.
Cool air isn't cheap folks. Most (small) home A/C are rated at 10,000 watts."
I live in Michigan and went through last summer with my Mariner Hybrid. I only found myself turning off the "Economy mode" on the A/C a couple of times to require the ICE to run all the time in order to provide cooling at stop lights or in slow moving traffic when the Mariner would normally be running in EV mode.
