Trying to keep the cabin from not be scorching hot next summer

most effective thing I have used so far:



Completely generic fit, but it's great. The one we have bounces out tons of heat and the real key is it deploys and stows fast so you use it every time. Saves a lot of energy that way.

 

Yep, I put those on all my cars. My windows are always down 1/4 inch and I gotta put up with the warning while exiting. The car interior will still get warm, but it isn't a blast furnace when you open your door.

 

Find shade tree - Open windows whenever possible ( if ever - ignore the windows open message in the MID and don't forget they are open if it starts to rain ....) - get a battery operated fan or if you're adventurous, run a three wire flat extension cord under the rear door and plug something in, wrap the extention cord in duct tape where it fits under the door https://99mpg.com/

 

The dealer does not (yet) have any window shades that fit the Gen 5 Prius.

 

Let us know how it works out. I am interested to know how cool it keeps the cabin and if it lowers fuel economy. It looks to significantly protrude from the side windows, which may increase the drag coefficient. Last year I bought a full set of custom sunshades for all 6 windows from the site below. The only window it dosn't cover is the the bottom portion of the rear hatch.

It's pricy, but they fit perfectly and practically block out all of the sun. Prior to that I used non-custom shades, but the magnets on the side window shades scratched the interior paint and never fit right.
