GMC Hummer EV Winter Vary-Examined In Bitter Nebraska Chilly

The GMC Hummer EV presents what I wish to suppose is a really American answer to getting as a lot vary as potential out of an electrical automobile: Use the most important battery you possibly can muster. It is like Scorching Rodding 101, however with a giant battery as an alternative of a giant engine. And on the top-spec Hummer EV3X SUV, you stand up to 312 miles (502 km) of EPA-rated vary from its 20-module, 170 kWh battery. 

However that is an optimistic quantity even when the climate is nice. How about when it is not good?

Tim Esterdahl of the Pickup Truck + SUV YouTube channel discovered in a trial by fireplace (or snow?) this weekend when he left his city in Nebraska to catch a flight in Denver 188 miles away. Usually, the Hummer EV can be greater than up for the duty, however Nebraska in January brings climate that is removed from optimum for electrical driving. The temperatures there have been within the teenagers these previous few days and into the negatives at night time.

Making that flight in such climate is a bit harrowing. The excessive temperature that day was about 14 levels F (or -10 C.) However it makes for a really fascinating EV winter vary check. 

 As Tim explains on the outset, the Hummer EV begins the day charged to 100%. That reads as 285 miles (459 km) of vary, so the SUV estimates a few 10% vary hit already. He heads to Cheyenne, Wyoming as a result of he is aware of there are charging stations there, and units off amid the single-digit temperatures and an entire lotta snow. 

Tim performs it good right here. He preconditions the inside cabin whereas the Hummer EV continues to be plugged in, which warms it up properly earlier than he is able to go. Then as soon as he begins his drive, he dials the heater down however leaves the heated seats on to preserve vitality. He is additionally good relating to charging; he decides early on that if he must juice up, it does not should be to 100% over a number of hours, however solely so as to add 100 miles or so—sufficient to comfortably attain his vacation spot. (That is type of the thought solution to deal with an electrical highway journey until you simply have loads of time to kill.) 

He additionally notes, appropriately once more, that having that huge battery within the flooring of the Hummer EV helps maintain the middle of gravity good and low, which helps with general stability and weight distribution when issues get slippery. As I’ve written myself earlier than, EVs are higher at winter driving than many individuals suppose. 

However the tradeoff goes to be lowered general vary as chilly impacts effectivity. And as you possibly can see, that is legit winter driving situations, not only a gentle breeze:

Like I mentioned. Chilly. 

However Tim has a decent schedule to maintain, so he commits to powering via—albeit fastidiously. He has reward for the Hummer EV’s regenerative braking, which additionally affords a better diploma of management in situations like this as a result of the precise brake pedal will get used much less whereas happening hills. Sadly, in snowy situations like that, Tremendous Cruise is out—and EVs do not warmth up their hoods like gasoline automobiles do, so he offers with extra ice than an ICE automobile would. 

After driving about 90 miles to Cheyenne, Tim notes that he solely has 98 miles of vary left. A Hummer EV is not an effectivity king on a very good day; right here, the mixture of freeway speeds and the chilly climate leaves him with about 98 miles of vary left. The Hummer EV reads a paltry 1.3 miles per kWh of effectivity, too. “I’ve simply been burning via this battery,” he says. Tim errs on the facet of warning (and he has to make use of the services anyway) so he costs prior to the Hummer EV recommends after which downs a sandwich contained in the cabin. 

And his conclusion here’s a fairly honest one: “The query in my head is, do you take into account this a hit or a failure?” It was a hit, he says, in that he was in a position to get to the airport on time, albeit with a cease alongside the way in which that wanted to occur regardless. On the identical time, he estimates about $30 or $40 for public charging. 

However, sure: as snug and distinctive because the Hummer EV is, that huge battery and virtually 9,000-pound curb weight are disadvantages for winter vary. At these temperatures, a full-bore 314 miles of vary is fairly out of the query—simply as it could be on any freeway highway journey, however it suffers greater than ordinary on this cold-weather check. 

Finally, it is a nice abstract of EV winter road-trip planning. You could suppose forward, know the place your chargers are, and you will have consolation and traction benefits which will surpass gas-powered automobiles. However there’s nonetheless a giant distinction between an EV’s estimated vary within the chilly and what you truly may get.
