This is a great shade for such a large windshield. I am amazed on how it really does help keep the interior cooler. I would say at least 20 degrees maybe more. I wish it wasn't so bulky. I would like to suggest something that is a bit more compact but keeps it cool. I would give more stars if it were more mobile.
