It is hard to believe something that heavy can move this fast.
The GMC Hummer electric pickup defies intuition. You see its bulk. You see the tires. Your brain says “no way.” Then it launches. The laws of physics feel like a suggestion.
GMC built a beast. It weighs nearly five tons. Yet the electric motors don’t care. They shove this mass forward with terrifying ease. The standard trim hits 60 mph in reasonable time. The top tier? It does it in 3.3 seconds. That is insane. It makes you question what is real.
You get all-wheel drive. Off-road gear. Surprising range for its size. But here is the trade-off. The brakes struggle. The range shrinks when you tow. And the price? It stings. If you just want a fast, cheap electric truck, look elsewhere. The Rivian R1T beats the Hummer on price and charging speed. But this is not a normal truck. This is a statement.
2027 Model Changes: New Colors and the ICON Edition
Not much changes for 2027. The mechanical bones are the same.
The updates are visual. New colors arrive. Dark Ridge. Azurite Blue. Dark Ember. Deep Void Matte. And then there is ICON Yellow.
This yellow recalls the school bus hue of the classic Hummer H2. It is reserved for a limited ICON|25 model. These units get black exterior accents. Serial badging inside. Unique infotainment graphics. It feels exclusive. Scarce. You pay for that scarcity.
Performance Specs: 1,000 Horsepower vs. 570 Horsepower
Which one should you buy? Depends on your tolerance for gravity.
There are two main paths.
– The 2X trim uses dual motors. It makes 570 hp. It is fast enough for most.
– The 3X trim uses tri motors. It makes 1,000 hp. It breaks the internet.
Both have all-wheel drive. The rear wheels steer. This helps you maneuver at low speeds. It saves parking spaces. Once you are moving? Forget it. You are piloting a brick.
Acceleration is where it shines. The Edition 1 trim we tested rocketed to 60 miles per hour in 3.3 seconds. That used a special “Watts to Freedom” launch control mode. GMC promises a new Carbon Fiber Edition next. They claim it will hit 60 mph in just 2.8 seconds. That would tie a Corvette. A heavier, slower-feeling Corvette. But a Corvette nonetheless.
The braking is where it falters. Slowing from 70 mph takes 211 feet. The brakes fade on repeated use. Yikes.
Towing Capacity and Range When Hauling Weight
Can you tow? Yes. But at what cost?
The 2X dual-motor model can tow 12,100 lbs. That beats the Ford F-150 Lightning (10,000 lbs) and the Rivian R1T (11,000 lbs). The tri-motor version loses this capacity. It maxes out at 7,500–8,500 lbs. More power. Less towing. Strange math.
We towed a 6,100 lb camper. The result? Range halved. It dropped to 140 miles while driving 70 mph. That is not a typo. Half. So if you plan to pull heavy loads. Bring a charger. Or a very long rope.
EV Range Test and Charging Speed Results
What is the real range?
The EPA claims up to 311–381 miles. The standard 20-module battery gives you 311 miles (2X) or 314 (3X). The bigger 24-module pack pushes the 3X to 381. If you add off-road gear? Drop to 359.
We drove our test truck at 75 mph. It stopped after 290 miles. That is a long drive. But it is not cross-country on one charge.
Charging is slow for its price tag.
– Peak rate: 287 kW.
– Average rate: 98 kW.
– 10% to 90%: Over 2 hours.
GMC claims you get 100 miles in 10 minutes. We took twice that long. The battery is huge. It takes forever to fill. You will be eating lunch at the charger. Every time.
Fuel efficiency numbers look good on paper. 59 MPGe city for the 2X. 46 MPGe highway. Remember. These are ideal conditions. The real world is heavier.
Interior Comfort: Luxury Materials vs. Convertible Style
Get inside. The seats are firm. The materials… adequate. For this price? You might expect better leather. You might want softer touchpoints. Instead. You get plastic that looks okay but feels cheap in places.
The cabin is tighter than a GMC Sierra 1500. Less room to spread out. Unless. You open it up.
This truck has removable roof panels. Three of them. Lift them off. Stow them in the front trunk (frunk). Suddenly you have wind in your hair. It is a T-top design like the GM sports cars of the ’70s. Or like the Jeep Gladiator. It is convertible pickup living. Do you want a convertible pickup? You probably say no. Then you do.
The back seat? Roomy. Plenty of legroom. You can fit a lot of people. Or a lot of things.
The bed is 5 feet long. Standard crew cab stuff. Door pockets are deep. The center console is massive. There is a place for every gadget. Just find the power outlet first.
Infotainment: 13.4-Inch Screen and Graphics Lag
The tech suite looks expensive. A 13.4-inch infotainment touchscreen. A 12.3-inch instrument panel. It is standard Bose audio. 14 speakers. The sound is rich. The display is crisp.
GMC hired Epic Games to build the interface. Yes. The Fortnite company. The graphics look stunning. It is beautiful. It lags.
We noticed delay. Button presses felt slow. The software wants more processing power. The hardware doesn’t quite have it. It looks like a video game. It sometimes runs like an old computer. You get wireless Apple CarPlay. Android Auto. Wi-Fi. OnStar is standard.
Safety Tech: Super Cruise and Standard Features
Safety gear is solid. GM’s Super Cruise comes standard. This allows hands-free driving on mapped highways. We liked it. It works well. It feels safe.
Other features include:
– Lane keeping assist.
– Blind-spot monitoring.
– Adaptive cruise control.
– Automated emergency braking.
– Pedestrian detection.
Crash test scores are pending. Check the NHTSA and IIHS sites for updates. But the passive safety suite is top-tier.
Warranty: 3 Years, 60k Miles Powertrain
You want coverage. GM gives the standard deal.
– Bumper-to-bumper: 3 years or 36,036 miles.
– Powertrain: 5 years or 60,060 miles.
– Battery: 8 years or 100100 miles.
– Free maintenance: First visit only.
That battery warranty matters. These batteries are large. Expensive. 100k miles is plenty. But you drive 100k? Good. You drove this thing for five years. You earned that wear.
Is it worth the wait? Maybe. The specs are wild. The GMC Hummer EV 2027 specs show a vehicle that prioritizes power over practicality. It is fast. It looks fierce. It tows less than its twin. It charges slow.
It is not for everyone. But if you can afford it? It turns heads. It makes noise. Not with an engine. But with acceleration. You will feel it. Your spine will feel it.
And when the brakes fade on the descent? You will think twice.
