Question

When your AC turned on in your car, does it burn more gas?

Answer 1

yes...but it's a complete mystery as to why.

Answer 2

no, just uses the battery power.

Answer 3

It takes about 5hp away everytime the compressor kicks in,they say it uses less gas then to roll the windows down,but yes it does use a little more gas.

Answer 4

Yes, AC cause additional drag on engine, however it is a catch 22 because rolling windows down cause a reduction in aerodynamics of the car.

I live in Texas, hard to imagine not using AC in an attempt to save gas during the summer if you have a working AC that is.

Answer 5

Yes it does, you are running a compressor motor.

Answer 6

in some ways yes

but either way if your windows are down you lose gas cause there no aerodynamic

if you have a/c more gas cause your making the engine work more so best bet is no a/c and windows up lol

Answer 7

yes, because the A/C compressor runs off of the engine, requiring more engine power to maintain the same speed

Answer 8

absolutely!!!! 10 to 40 % power robbed! like turning a 4.0 liter motor into a 3.5 liter power wise. the A/C fuel loss is lessened on long non stop drives with all windows closed. City driving it takes its toll milage wise.

Answer 9

yes
