Bjorn wetting himself again. This time cruising at 120MPH (on German autobahn). In practice traffic got in his way, but he rarely fell below 90MPH. He was interested in battery temperature and consumption. Although he pressed on, after a slow car pulled over, he was trying to only use 50% throttle
He did a similar test in his original M3P (and, from memory, in his MX) and makes a comparison between them.
Its a 1 hour video - no edits I think, and he jabbers to the camera the whole time ... in his inimitable style. Results start 54 minutes in:
Summary: battery temperature was not an issue (i.e. for a steady 120 MPH cruise, rather than track-style repeatedly flooring it)
Charged at Tesla supercharger (dunno if it would charge faster on V4 / Ionity
et al) ramped up to 250kW
If my conversion maths is correct that was 660 wH/mile, 140 mile range
