The original Hummer was originally developed for military use, with little regard for fuel economy or urban maneuverability. Civilian versions proved popular with American buyers keen on excess and after a few years away the Hummer name is back. This time it’s playing toy soldiers and has returned with an all-electric powertrain. However, I don’t think it has become a green machine.

Electric cars often weigh more than equivalent gasoline or diesel cars, but none are as portly as the GMC Hummer EV. It weighs the best part of four and a half tons. A good chunk of that (1.3 tonnes) is attributed to the massive 213kWh battery pack, which alone weighs more than a Smart EQ ForFour.

Weight affects many things negatively: handling, braking, efficiency and performance. Hummer gets around the last of them with the option of a 986bhp triple-motor electric powertrain, like a Tesla Model S Plaid, which is good for a 0-62mph time of just 3.5 seconds if you activate the launch mode called ‘Watts To Freedom’ .

While getting up to speed is no problem, reigning in all that weight is not a pleasant experience. It takes a lot of space to brake from highway speeds, and regular hard braking will quickly cause brake fade.

Low-speed driving is actually less of a chore than you might imagine, with four-wheel steering dramatically improving maneuverability. Not that you’d want to drive the Hummer EV around a quaint British village, due to its tall dimensions. At higher speeds it is unwieldy and you are always aware of its width. Fortunately, a range of cameras help here.

We didn’t get a chance to take it off-road, but this is where the Hummer EV should come in handy. With a track almost as wide as the original Hummer H1, the new car has the same party trick of being able to follow tank tracks. Optional air suspension should be a boon on rocky trails, while the four-wheel steering even allows for diagonal crab-like driving. How useful any of this will be on city streets remains to be seen.

It would probably measure up to its main rivals—the Rivian R1T and the Ford F-150 Lightning—in rough terrain, but those trucks are better at practical truck stuff. The Hummer trails the competition in terms of payload, cargo bed size and towing capacity. That may not matter to Hummer buyers, as the majority probably plan to use it as a lifestyle vehicle rather than a true workhorse.

After all, buyers focused on pure utility are unlikely to spend around $100,000 (roughly £85,000) on a work vehicle. Regardless, it seems the majority of that cost is due to the massive battery pack and monstrous powertrain, as the material quality inside is quite disappointing in places.

Sure, you can remove the roof and the mechanism and parts for it are impressive, but a lot of the cabin plastics feel too cheap for a car that costs that much. Like the convertible, the cargo space basically becomes a space to store the roof. Although there is a practical 320 liters of extra storage space under the bonnet.

There are plenty of standard features, including a 13.4-inch central touchscreen and 12.3-inch digital driver display, plus GMC’s SuperCruise semi-autonomous driving technology. The graphics come from the same company that makes video games like Fortnite, although there is some lag, which is hard to justify in this price range.

The Hummer has an official range of 329 miles, which is reasonable (until you consider the size of the battery). In reality, you should get close to 300; our test car had 75% charge and a range of 229 miles. The efficiency was around 1.5 miles per kWh, so the Hummer will still cost a lot to run even on electricity.

Like the Porsche Taycan, the Hummer uses 800-volt technology for charging speeds of up to 300kW; find a compatible fast charger and nearly 100 miles of range can be added in 10 minutes (on the sold-out Edition 1). It will take a long time to charge the Hummer on a less powerful charger – as much as a day and a half on a 7kW home wallbox.
