Yeah, if I really need to goose it on a merge or something, I shut down the A/C in the Civic before I do, no joke. I almost got killed once with A/C & Eco mode on merging across a busy highway to a quick left-hand exit, because it was so incredibly sluggish 😳 So I don't use Eco mode ever, for starters, and if it's really fast, packed traffic on a merge, I just turn off the A/C for a minute. It's usually only really bad if it's a hot day, and the merge is an uphill ramp, and traffic is moving at like 70+ and is tightly packed (in other words, every day of summer in Connecticut lol).
The rest of the time it's pretty much fine, but I kind of would have liked to have taken an Si out to see how much better the engine in that was. My Kia Soul was around 170 HP and it was always plenty for merging and darting around traffic as needed with no little gimmicky tricks to make it work in certain situations. On the flip side, I've been driving our Civic for the last couple of weeks while my wife has been out of town and I've been average 36 mixed city/highway with the A/C nearly full blast and a bit of a lead foot, so the extra savings at the pump makes the minor annoyances it worth it!
I never heard of a modern car that did not shut the a/c compressor off when you floor the gas. On cars that are a bit older, you needed to press the pedal far enough to trip the WOT switch. On modern computer controlled cars it's usually enough to just boot the throttle pretty good. Even my Jeep with the Hemi turns off the A/C compressor when I get on it.
