Which Hummer EV year to buy used
Our verdict · Felix Hartmann
Our verdict depends on what you want from the truck:
- Lowest entry price: a 2024 or 2025 2X. You still get four-wheel steering and air suspension, and the 2025 trucks can take the NACS adapter.
- Maximum range: a 3X pickup with the 24-module battery. It has the longest EPA rating of the range, up to 571 km.
- Collector value: an Edition 1 or an Omega Edition. Both are documented limited runs, but the Edition 1 has the early range rating.
- Newest hardware: a 2026 car, with King Crab from the factory and vehicle-to-home charging.
On any used truck, check that the software is up to date and that the King Crab update has been installed on 2022–2025 cars. Count the Sky Panels and their storage bags, and check the 35-inch tyres, which are expensive to replace. The truck is very large: the pickup is 2,202 mm wide, so measure your garage first with our will-it-fit tool. In Europe, any version weighing over 3,500 kg needs a C1 licence, so the Hummer EV stays a specialist import.

The GMC Hummer EV has five model years so far. It started in 2022 as a three-motor Edition 1 pickup and gained the SUV, cheaper 2X versions and the Omega Edition for 2024. The 2025 model was a carry-over. For 2026, King Crab became standard and a Carbon Fiber Edition arrived.
In short
- 2022: Edition 1 pickup only, 746 kW (1,000 hp) and an EPA range of 529 km.
- 2024: the SUV joins, the two-motor 2X appears, and the Omega Edition is built for one year.
- 2025: no mechanical changes; new colours, an NACS charging adapter and a home bidirectional charger.
- 2026: King Crab standard, vehicle-to-home charging and a 3X with a GM-estimated 865 kW (1,160 hp).

What GMC promised in 2020
GMC revealed the Hummer EV pickup in October 2020, ten years after the original Hummer brand was wound up. The story of that first brand is told in our history of Hummer. Production was assigned to the Detroit-Hamtramck plant of General Motors, renamed Factory ZERO for electric vehicles.
The launch plan described four versions. The old 1cars text, written from GMC's 2020 announcement, listed them as follows:
| 2020 plan | Motors | Power (claimed) | Range (claimed) |
|---|---|---|---|
| Edition 1 | 3 | 746 kW (1,014 PS) | about 560 km |
| EV3X | 3 | about 597 kW (811 PS) | about 480 km |
| EV2X | 2 | about 466 kW (634 PS) | about 480 km |
| EV2 | 2 | about 466 kW (634 PS) | about 400 km, coil springs, no rear steer |
Two things changed on the way to the showroom. The base EV2, with coil springs and no four-wheel steering, never joined the line-up; from 2024 the range was simply 2X and 3X. And the Edition 1 was rated by the EPA at 529 km (329 miles). By our calculation, that is about 5–6 % below the 560 km first promised.
2022: the Edition 1 pickup
The first customer trucks were built from 17 November 2021. Every 2022 Hummer EV was an Edition 1 crew-cab pickup with three motors, one at the front and two at the rear. In its Watts To Freedom launch mode it gave 746 kW (1,000 hp) and a GM-quoted wheel torque of 15,590 Nm (11,500 lb-ft).
The Edition 1 carried everything: adaptive air suspension with Extract Mode, rear-wheel steering with CrabWalk, removable Sky Panel roof sections and 35-inch tyres. The reservation book filled within minutes of opening. According to GM's US sales reports, 854 Hummer EVs were delivered in calendar 2022, a slow start for a truck with that much demand.
2023: the 3X pickup arrives
For 2023, the 3X pickup joined the Edition 1. It used the same three-motor layout and was aimed at buyers who wanted the full performance without the launch-edition trim. Deliveries grew to 3,244 in 2023, again from GM's US figures. Production of the SUV began at Factory ZERO on 30 January 2023, but it was sold as a 2024 model.
2024: the SUV, the 2X and the Omega Edition
The 2024 model year was the biggest step. Three changes came at once:
- The SUV. It is about 508 mm shorter than the pickup (4,999 mm against 5,507 mm) and has a shorter wheelbase. Its three-motor 3X gives about 619 kW (830 hp), and its EPA range is 480–505 km (298–314 miles).
- The 2X. This two-motor version gives 466 kW (625 hp). GM's figure for its wheel torque is about 10,030 Nm (7,400 lb-ft). It keeps four-wheel steering and adjustable air suspension, so it is not the stripped EV2 of the 2020 plan.
- The Omega Edition. It was a one-year special on the 3X with Neptune Blue Matte paint, 18-inch beadlock wheels, a Kicker audio system and the Infinity Roof. The encyclopedia count is 550 pickups and 1,108 SUVs.
Sales reached 13,993 in 2024. The extra versions roughly quadrupled deliveries compared with 2023.
2025: a carry-over year
GM Authority's comparison of the 2025 and 2024 trucks lists no mechanical changes. The pickup and the SUV each came as 2X or 3X. The listed batteries were a 20-module pack of about 170 kWh and, on the 3X pickup, a 24-module pack of about 205 kWh. GM quoted 311 miles (about 500 km) for the two-motor trucks and 314 miles (about 505 km) for the three-motor SUV.
The 2025 changes were about charging and appearance:
- A dealer-fitted NACS DC adapter, so the trucks can use Tesla-standard fast chargers.
- The GM Energy PowerShift home charger, bidirectional and up to 19.2 kW.
- A Dark Essentials package with black badges, a black recovery hook and 22-inch gloss black wheels.
- New paint colours, Graphite Blue Metallic and Solar Orange. Four colours and the Omega Edition were dropped.
US sales rose again, to 15,788. By our calculation, about 33,900 Hummer EVs were delivered in the US from 2022 to 2025.
2026: King Crab and the Carbon Fiber Edition
GM announced the 2026 changes on 15 May 2025. Production began later that year at Factory ZERO.
| 2026 change | What it means |
|---|---|
| King Crab standard on 2X and 3X | at low speed the rear wheels turn faster than the fronts, for tight off-road turns |
| Over-the-air update | King Crab also promised for 2022–2025 trucks |
| Bidirectional charging | vehicle-to-vehicle and vehicle-to-home, with GM Energy hardware sold separately |
| 3X pickup, 24-module battery | GM estimate 865 kW (1,160 hp) and 17,600 Nm (13,000 lb-ft) of wheel torque |
| Carbon Fiber Edition | 3X pickup or SUV, 24-module battery, 22-inch carbon wheels, carbon mirror caps and skid plate |
| Super Cruise | Google Maps lane guidance and a hands-on mode |
| Ride | retuned dampers |
GM quotes 0–60 mph in 2.8 seconds for the Carbon Fiber Edition pickup, measured on a closed course. New colours are Coastal Dune and Auburn Matte, and new cabin themes are called Granite Drift and Stealth Eclipse.
