MSantos,

Thanks for the comments.

I thought about the AC settings question, but had somewhat of a time constraint where I could not wait for Auto at xxF degrees to be steady state. My intent was to try to illustrate the impact of FE by using max AC. I thought setting it to 58 (not in AUTO) and once through air would keep the AC load on the engine.

I also wanted to avoid forced regen, so I limited the the consecutive conditions with AC to two. I would have tracked the SOC start/end as well, but had to keep eyes on the road. It did stay between 5-7 bars though.

Certainly, most drivers will not run AC at max settings for extended periods. Maybe these results just show a worst case impact of using AC versus none at all. What suprised me a little was that at "high" speeds, the additional impact of AC load is smaller.
