She is talking about the Ultium platform (think Silverado EV), not the HummerEV specifically. With the HummerEV aerodynamics I expect right around 350 miles of EPA range (less on a straight freeway run @65 mph, and much less if you drive 75-85 mph), assuming the battery is 200 kWh. If the battery has more capacity, more range is possible, but I do not think GM massively understated their range on the HummerEV.Inside GMC HUMMER EV’S battery technology
Anyone else catch her saying the current battery technology can produce up to 450 miles of range based on configuration? She says it right after going though all of the ways the batteries can be configured with the double stack Hummer being the largest configuration. This portion starts about halfway through.
With 350 miles being the current publicly released range, I hope this is another example of Al’s motto of “under promise, over deliver” (or something like that).
Realistically, because you do not get 0-100% effective use typically, if I am planning a highway road trip, I figure I will be charging every 200 miles, dropping to about 100 miles with a trailer. I think in the Hummer Ev your trip will go faster if you drive slower, but that will be hard to do in the Hummer Ev, with such an awesome looking truck it will be hard to putt putt in the slow lane, so plan extra charging stops. Not much different then earlier Hummers stopping for gas, they did not go far on a tank of fuel.
