Is it true that using A/C in your vehicle increases fuel consumption?

Answer 1

Yes, when the ac is running the engine has to turn the pulley that is on the ac compressor. This puts more load on the engine making it work harder, so more fuel is consumed.

Answer 2

yes it is true.have you ever seen the show myth busters? well they were testing to see weater using AC will increase fuel consumption or having the windows open while driving.So they took two identical cars one is going to have the AC on full and the other one is going to have the windows open while driving and those 2 identical cars have the same amount of fuel in them. Now two drivers started to drive these 2 cars at the same time at a driving range and see which car will stop first ( from lack of fuel) well it was the one with the AC on...and the other car was still going ... so what we learnt is that having the AC on will increase your fuel consumption..so maybe it is a better idea to roll your windows down to save some money..or just better buy a convertible lol

Answer 3

Yes and No! When you drive under about 50 miles per hour, then it is more efficient to roll down the windows than run the A/C. However, going faster than that causes an adverse effect because of air resistence - rolling down the windows creates drag, and at about these speeds is when drag uses as much fuel consumption as running the A/C.

Answer 4

The AC compressor uses the engine to circulate freon through the system to keep you cool. It takes energy from the engine which in turn takes additional fuel. The newer systems are many times as efficient as ones from a few years back, but they still reduce the mileage a bit. My stats are 28.0 mpg with air off 26.2 with it on using the same drive and the same time of the day. However many things degrade the gas mileage to a greater extent. Driving erratically and speed can have a greater effect than the AC.

Answer 5

with modern cars, driving with the windows shut and the A/C on reduces fuel consumption as the air passes around the car better. With the window open the air flow is not constant increasing drag and fuel consumpsion

Answer 6

yes it does increase the amount of fuel usage. do to the fact that it is a motor driven by a belt and when the condesor kicks in there is a pull on the motor try running your ac untill the car gets cold the turn on the recirculation and turn off the ac it sould recirculate the cold air until the sun warms it

Answer 7

Last time around, in "AC vs. Windows Down", the MythBusters concluded that using AC was more efficient than opening your windows to cool down. However, they quickly admit that they were wrong to make such a hasty confirmation. In fact, they find that over 50 mph, you're better off with AC on, but slower than that, open your windows. Myth busted.

Answer 8

Here is a great fuel saving trick, you no longer need to worry when you have your A/C on especially with winter approaching.

It works for me fine.

Answer 9

Yes, When you use the a/c you increase the load on the engine from the a/c compressor

Answer 10

Why do the batteries on your digicam pass flat faster in case you make the most of the flash? .... your automobile engine runs your AC ... so in case your AC is off the gasoline intake is conventional ... if the engine has to paintings more beneficial sturdy to stress the compressor of your AC then your gasoline intake will strengthen
