Outdoor x Indoor Temperature correlation?

[JAR897]

HI all,

Has anyone got any data points or articles/references on how the outdoor temperature impacts the inside temperature? I'm keen to understand - eg. If it's 23*c outdoors, what's the temperature likely to be inside? Etc Etc?

Its down to how much sun you have.

Sunny day it can exceed 50C inside without cabin overheat protection on. Latter seems capable of keeping things below 39C.

It's not so much the ambient temperature as it is the sun hitting the car.

Assuming full sunlight hitting it, I've seen cabin overheat kick in at ambient temperatures of around 24C. On days like that once it has kicked in it seems to keep the car awake for a few hours in a cycle of fans/AC on, then off, then on, etc.
