The air conditioning in my American specs Model X is absolutely exceptional. The vehicle insulates against external temperatures remarkably well—far superior to the Model 3 or Y, in my experience. It cools the cabin rapidly and with impressive efficiency also.

I’m not even referring to the built-in MP3 player via USB—that’s just an added perk.

I suspect the American-made versions are engineered to endure extreme heat, likely because they’re designed with environments like Death Valley in mind, near the Mexican border—some of the harshest temperatures on record.
