Everything about the GMC Hummer EV is big and over the top. Just a few examples of this include the off-roader’s peak output (upwards of 1,000 horsepower), its speed (0-to-60 mph in as little as 3 seconds), and its curb weight (over 9,000 pounds). It should come as no surprise, then, that charging this beast can be rather costly as well.
In a recent report, Car and Driver says it took the GMC Hummer EV to a local quick-charger station to see how much it would cost to bring the onboard GM Ultium battery pack up from a 10-percent charge to a 90-percent charge. According to the publication, adding this extra 80 percent of battery charge cost $81 at a rate of $0.43 per kWh, taking an hour and 49 minutes to do so.
Indeed, by modern EV standards, that’s rather pricey, not to mention quite a lengthy charge session for a DC quick-charger station. Of course, those numbers should be viewed with consideration for the GMC Hummer EV’s total battery capacity, rated at a rather ridiculous 212.7 kWh. By comparison, the new 2023 Chevy Bolt EUV has a battery capacity of 65 kWh.
Car and Driver also points out that the Hummer hit a peak charge rate of 287 kW, making for the second-highest charge rate among the 20 competitors in the publication’s “EV of the Year” contest, bested only by the Lucid Air. That said, the Hummer EV’s average charge rate was a much-lower 98 kW. Car and Driver also adds that the charge session was done at an Electrify America station in Michigan, which added a 6-percent sales tax to the equation. Additionally, the charge was not 100-percent efficient, losing approximately 5 percent of charge over the course of the session.
Indeed, although the GMC Hummer EV does not produce any local emissions, it is most definitely not energy efficient by any measure. As one might expect, given the specs and heritage.
