OK, clickbait title, I do not know the result of the InsideEV range test yet, but figure those of us owners should make some guesses?

I had guessed around 300 miles, I am seeing closer to 400 miles in mixed driving, but it definitely is lower on the highway. What do you folks think the 70 MPH range test result will be?

Guessing 313. Most of when we were driving the Hummer at 70 mph was in sub-freezing temps and it'd still get maybe 280 miles of range from 100% to 0%. Otherwise I drove 10 over on our trip, which was more like 250-275 miles of range in warm weather.

If he's in Ypsilanti, we've had shit weather here the last few days so it's going to definitely impact the range.
Ya, he was in Detroit, so I wonder what conditions he got? Weather makes a big difference.

What are you using as battery capacity? My truck was reporting over 214kWh. Our first real big drain of the battery was in below freezing weather, calculated out around there as well. I'm not sure if Ultium reports a lower capacity in cold weather but my Bolt would report about a 5% capacity loss just because of the cold that would come back in the summer.
@Tom E-Tron: I concur. My range modeling software says 297 miles @ 70 deg. F/sea level. See below. That will probably be Tom Malough's. When Kyle Connor does it, driving from mile-high Ft Collins, the spreadsheet suggests he'll probably do an "amazing" 330 miles.

Note also that at 80 mph, it shows about 257 miles, fitting with @Dark-Fx 's 250-275 trip result.

It's going to be interesting to find out what Tom came up with, I am expecting it to be close to 300 miles, maybe a hair over.

Yes, Tom witnessed other EVs charging normally even using the dispenser he abandoned, which strongly suggests a vehicle issue. If this EV was a GM press loaner, I’d have expected GM would have verified it was 100% prepared to not have issues. So what happened? I’m sure when Lucid let Tom test theirs for the first time, they dress-rehearsed both the vehicle and the charge station, knowing the PR stakes. I’m seeing conversations on all the GM EV forums asking about the fast charging expected and, to-date, we have seen nothing other than anecdotal posts from owners charging in various non-ideal situations. The only actual non-NDA’ed owner of a dealer-delivered Lyriq communicating on their forum has reported speeds not even close to GM’s claims, even under apparently good conditions.

Tom’s range test was a GM home run, but the failed charge session was like hitting a home run and then forgetting to step on home plate.
The Hummer charging does have some quirks, I have seen too, on EV-Go, our other EV's start at a hight rate then taper, but the Hummer starts at its high rate, and will have dramatic drops, then go back up, then drop again, sometimes dropping to as low as 20kW, then back to 150 kW within a minute. GM definitely still has work to do on the battery management.
