Here's the Fastest Way to Cool Down a Hot Car

posted by Aaron Zytle -

You might think that just blasting the A/C on max is the fastest way to cool things down, but it's actually a little more nuanced than that.  The people at Thrillist ran an experiment where they tried to cool down a hot car using four different methods:

  

1.  Blast the A/C but keep the car parked the whole time.  

2.  Blast the A/C and drive with the windows down. 

3.  Blast the A/C and drive with the windows up. 

4.  Roll the passenger window down . . . fan the car with the driver's side door . . . then blast the A/C and drive off with the windows up. 

 

And they found that the fastest way to cool down your car was actually option #4 . . . where you roll down the passenger window and fan the car with the driver's side door about a half dozen times.  

Apparently that creates a low-pressure system that literally sucks the hot air out of the car. 

It cooled the car at a rate of about 3.6 degrees per minute.  Which was half-a-degree better than the next best option, blasting the A/C and driving with the windows up.  Now you know.
