My family had two volvos that behaved like this. One was an '81 Volvo 240 DL manual, and the other was a '92 Volvo 740 automatic. Both of them could get up to highway speed noticeably faster if you turned off the A/C. (My dad used to say they’d “do 0 to 60 on a leisurely afternoon.”) There’s some chance that A/C was aftermarket on the '81, so maybe that’s a factor? But the '92 did it too, and that was definitely stock.
Then turning it off doesn’t give you more power in those cases, and even those ones will limit the kw output to the electric AC during wide open watts if the battery can’t supply the output. But most evs don’t need to turn off the ac because the battery output exceeds the electric motor requirements
Ice vehicles automatically turn off the AC at wide open throttle.
Some do if the belt drives the compressor. Humans have built many cars, exceptions exist
Belts drive the clutch. I haven’t seen a single production car that has a direct driven compressor.

I can believe it, i was talking about cars made this century. The care from the 1900’s were something else.
Im thinking of something where an electric motor does it so probably a hybrid… Maybe a Lexus
