GMC Hummer EV Winter Vary-Examined In Bitter Nebraska Chilly

The GMC Hummer EV presents what I prefer to suppose is a really American resolution to getting as a lot vary as potential out of an electrical car: Use the largest battery you’ll be able to muster. It is like Scorching Rodding 101, however with a giant battery as a substitute 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 sweet. How about when it is not good?

Tim Esterdahl of the Pickup Truck + SUV YouTube channel came upon 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.) Nevertheless 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 couple of 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 power. He is additionally good in the case of charging; he decides early on that if he must juice up, it would 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 concept option to deal with an electrical street journey except you simply have loads of time to kill.) 

He additionally notes, accurately once more, that having that large battery within the flooring of the Hummer EV helps preserve the middle of gravity good and low, which helps with total 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 diminished total vary as chilly impacts effectivity. And as you’ll be able to 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 by way of—albeit fastidiously. He has reward for the Hummer EV’s regenerative braking, which additionally affords the next 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 fuel automobiles do, so he offers with extra ice than an ICE car 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 day; right here, the mix 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 by way of this battery,” he says. Tim errs on the aspect of warning (and he has to make use of the amenities anyway) so he costs ahead of the Hummer EV recommends after which downs a sandwich contained in the cabin. 

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

However, sure: as comfy and distinctive because the Hummer EV is, that large 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 will be on any freeway street journey, nevertheless it suffers greater than typical on this cold-weather check. 

Finally, this can be a nice abstract of EV winter road-trip planning. You might want to 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.
