A small sample size, but I had an R2 demo drive in 98 degree F Orlando from 11:30 to noon and no cloud cover. The AC was cold and the ventilated seats were excellent. I was concerned about radiant heat coming down from the glass roof but I didn't notice anything.
Related to the topic of this thread - how is the A/C performance when the car idling? Sorry, I’m new to EVs, and in ICE, air moving through the engine helps. I sit in carpool in NC heat (95 degrees) in the summer for an hour daily, so an EV would really help me in keeping the cabin comfortable (VS running an entire engine just to run the A/C compressor)
Mid 90s here today. Can't provide useful info, too busy enjoying all the windows down.
Still got some chill from also having the AC running, but I was never truly comfortable. For comparisons sake, today my R1T was warm my whole drive with the windows all up though.
