I pre-chilled my R2 and R1S to 68 degrees, set Pet Comfort mode in both, and let them sit in the midday sun for 45 minutes with thermometers in every row to see which one actually keeps your pet more comfortable.

Note: Both the R1S and R2 are tinted using Llumar Ceramix IRX. The rear is 30% over the factory tint, the front windows are 15%, and the windshield is 50%. The glass roof is factory on both.
