GM shrinks the Hummer and shows an electric off road SUV that wants to fight Bronco and Wrangler

The smaller Hummer is not a small car

The Hummer X SUV measures 4782.5 mm long and 2032 mm wide, with a 2945.5 mm wheelbase. That makes the concept roughly 216 mm shorter than the production GMC Hummer EV SUV without its spare wheel, which measures 4999 mm. Include the spare wheel on the production model and the difference grows to nearly 468 mm.

The Hummer X Truck is 5264.5 mm long, with a 3318.6 mm wheelbase. By comparison, the current Hummer EV pick up stretches to 5507 mm, so the concept cuts about 243 mm from its length. In Hummer terms, that is a major step. In a European car park, a vehicle 2032 mm wide remains a fairly serious spatial examination.

The off road geometry says more than the design talk

The Hummer X SUV is not just a shorter design exercise. Its 334.3 mm ground clearance, 44 degree approach angle, 46 degree departure angle and 30.9 degree breakover angle give it proper off road geometry. The 37 inch Goodyear tyres work out at roughly 940 mm in outside diameter.

The Hummer X Truck takes a slightly different route, with 316.7 mm of ground clearance, a 41.5 degree approach angle, a 29.7 degree departure angle and 35 inch tyres, equal to about 889 mm. The SUV therefore looks like the more aggressive rock crawler, while the pick up puts more emphasis on usability and proportion.

Bronco and Wrangler sit directly in the sights

By size, GM places the Hummer X SUV very deliberately in Ford Bronco and Jeep Wrangler territory. A four door Bronco Base has a 2949 mm wheelbase and a length of 4811 mm. The Jeep Wrangler 4 Door gives 3007 mm between the axles and measures 4785 mm long. The Hummer X SUV is essentially the same length, but much wider and with greater ground clearance.

In the electric field, the Rivian R2 appears as the obvious comparison. Rivian promises 244 mm of ground clearance, a 25 degree approach angle and a 26 degree departure angle. The Hummer X SUV clearly beats those geometric figures, but Rivian has the advantage that matters most: the R2 is actually heading for production. For now, Hummer X remains an idea laboratory.

FLEX FAB is the real story

The most interesting part is not the Hummer name, but the production logic. GM uses Hummer X to showcase FLEX FAB technology, where metal parts can be made in small runs without dedicated press tools. The concepts use FLEX FAB for 57 percent of their parts, hinting at how a manufacturer could one day build niche models, special editions and replaceable body panels with less investment risk.

That suits Hummer’s image neatly. Removable wheel arch extensions, visible bolts, replaceable parts, mechanical fasteners and less reliance on adhesives make the car feel more like a tool than a disposable design object. GM also links this to circular manufacturing. Parts of the seats and dashboard use materials from recycled bumpers, while components should be easier to remove and replace.

Hummer Hub and a drone add the science fiction layer

The digital centre of Hummer X is Hummer Hub, a connected suite of apps intended to link the vehicle, driver and adventure route before, during and after a journey. The showpiece feature is a scouting drone that flies ahead on the trail, sends terrain data back to the vehicle and later docks itself again.

It sounds like motor show theatre, but the idea makes sense off road. Today, a driver uses a spotter, cameras or simply gets out and looks. A drone could digitise the same role, reducing the risk of driving a two tonne or three tonne electric off roader blindly onto a rock, into a ditch or up a sand bank.

The powertrain remains secret

GM did not release figures for the Hummer X battery, motors, output, weight or range. So it would be unwise to compare the concept directly with the power figures of the production Hummer EV. The current Hummer EV pick up offers up to 865 kW, up to 584 km of estimated range and a 0 to 97 km/h time of about 2.8 seconds, but a production Hummer X might need a smaller battery and a lighter structure.

Weight would decide its real value. The biggest problem with the Hummer EV is not power, but size and mass. If GM could pack the Hummer attitude into an electric off roader roughly the size of a Bronco, it would create something the market barely has at all: a luxurious, rugged, modifiable electric rock machine.

European view: no sales model yet, but the idea is strong

For Europe, the Hummer X is not something to look for on a price list. GM states clearly that the concept is not for sale. Even the current Hummer EV is mostly a grey import, specialist dealer and enthusiast story here, because the US base price of 97,200 dollars means about 83,500 euros before VAT, transport, customs and conversion costs.

Still, the idea matters for Europe. The Mercedes Benz G Class, Ineos Grenadier and Wrangler show that emotional off road vehicles still have buyers here. Hummer X would add electric power, modular construction and a design that does not apologise for its brutality. The problem is simple: GM first has to decide whether Hummer becomes a real model family or stays a brand symbol orbiting one expensive electric giant.

Technical snapshot

Hummer X SUV: 4782.5 mm long, 2032 mm wide, 2945.5 mm wheelbase and 334.3 mm ground clearance.

Hummer X Truck: 5264.5 mm long, 3318.6 mm wheelbase and 316.7 mm ground clearance.

SUV off road geometry: 44 degree approach angle, 46 degree departure angle and 30.9 degree breakover angle.

Tyres: 37 inch Goodyears for the SUV and 35 inch Goodyears for the pick up.

Production logic: 57 percent FLEX FAB content, with the aim of supporting small runs, modularity and easier part replacement.

Status: GM does not plan to put the Hummer X into production or sale in its current form.

For now, Hummer X is only a concept. But it points to a more interesting future than simply making electric excess heavier, louder and more expensive.
