Noticeable engine load from running AC?

Hi all.

I upgraded from a F250 7.3L diesel to a 2015 Tacoma (4x, v6, 6-speed) back in February.

So far everything is great, but I have one nagging question. I find that running the A/C has a very noticeable drag on engine power. I can ask the dealer, but wanted to first ask if others find it easy to notice the A/C is on just due to the truck feeling a bit sluggish. Not a lot, but I'm surprised I can tell.

I understand my last truck had more torque, but this one is actually higher in horsepower. (Ok, 236 rated instead of 235. But still...

 

yeah you feel it... It is also one of the things i noticed when i switch to my 2013 taco from a 01 chevy 2500hd with the 6.0L v8.

I have noticed the more i use it the less noticeable it is... as if the compressor is freeing up etc.

You will also feel the "bump from behind" when sitting at a stop light and the AC kicks on and the idle goes up a 1-200 rpms.

 

Compressor definitely steals some power. There are a couple choices on the air selector knob that do t run the compressor. Feet and maybe in your face. I only use it when I need it.

 

FYI i have done the mod so that the feet / defrost or defrost only DOES NOT run the ac when selected.... essentially i have manual control over AC regardless of where the air is directed.

Its a simple quick wire mod in the cab.

 

Do tell.

Thank you.

 

I've notice that 'bump from behind' feel sitting at the light. First time I really thought someone bumped me!

 

It is all about the torque.

 

Ok, thanks all for the confirmation that it's normal.
