I'm surprised we have not seen posts then of power at 75 mph on level ground with no wind.
Each direction, for the finicky
It's on my list of things to do. Maybe next weekend...
Closest I've seen reported is 65 mph on flat ground, no wind, sea level at 48F, no HVAC. The screen indicated 18kW. My model, at that air density, predicted 17.5kW. Pretty close considering the screen indication rounds off any decimals.
Here're my latest guesses for energy consumption for the Bolt EV and IONIQ Electric. Warm temp, no HVAC, etc.
Bolt EV at 75mph is 320 Wh/mi...187mi.

The drag model says a combined 15.8 kW for air and tyres, so 2.2 kW for the rest.
At 75 mph, 22 kW for air and road, so 22 + 2.2*75/65 = 24.54 kW total anticipated.
That works out to 327 Wh/mile and presuming 59.5 kWh usable battery capacity, a range of ~ 182 miles.
HybridCars.com double-checked this claim with GM's press spokesman and the press rep says the actual result was 170 miles at 70 mph (not 92).According to the TFCL guy, GM said the Bolt could travel 170 miles on a full charge at WOT (Wide Open Throttle @ 92 mph).
The rep says the GM engineer who was quoted as making that claim either misspoke or was misunderstood.
The new "170 miles at 70 mph" now seems perhaps pessimistic to me, offhand. I think we need to crowd-source some of these numbers for ourselves and find a consensus result. I'm not really trusting any of these sorts of numbers until that happens.

Anything that spins
The electronics should be a fixed power drain but I was too lazy to try and separate that component.

Norway is apparently very hot for the AmperaE:

Huh
I started from air resistance based on Cd, air density and frontal area, and tyre rolling resistance and car mass.
The calculated forces exclude the drivetrain.

Does this mean that the salesman who gave me a test drive was wrong when he told me, "range is 238 miles no matter how fast you drive"?!

I hate to say this, but I'll guess that really happened.Does this mean that the salesman who gave me a test drive was wrong when he told me, "range is 238 miles no matter how fast you drive"?!

I don't know, Bruce. Car salesman are known far and wide as the most reliable source of information about their cars - and you know you can trust them because they have absolutely no motive to mislead whatsoever.

How foolish of me to doubt.
And for @SageBrush, yes, the Chevy salesman actually told me that range is same at any speed.

Bear in mind, though, that the liquid advantage is moderated by the necessity of dissipating the heat to the atmosphere via radiators, so the last step relies on the heat capacity of air. Of course, it is vastly easier and more efficient to use liquid in the cramped confines of the battery pack than to try to force air uniformly through the pack.
