I am guessing the Bolt does not have Solar Glass? It was in the 80's this afternoon, I did not put up sun shade and left windows all rolled up this morning. Getting into the car at the end of the work day... it was HOT inside and temp was 111F on the dash display in late afternoon...

No Solar Glass, the side windows are just slightly tinted, but the main problem is the huge windshield and equally huge dashboard.
I always leave all four windows cracked a bit during the summer just to let the heat out.

I put the windshield and the passenger front shade up and left tiny gap in the front window today. Nice and comfortable when I got in the car at the end of the day.
