While we all know what the GOM is good for, in this case, for curiosity sake, this was the highest I have ever seen. This was with extra range extended charge, 85 degrees, and driven 11 miles averaging 4 mph and using 3 mpkWh. I think I must have done a bit of coasting and creeping during those 11 miles.
I am sure people have experienced extra long range in theirs on actual extended trips. That of course is the real range test, not the GOM.
