GMC Teases Off-Road Concepts: The Hummer X Duo
General Motors (GM) recently pulled the wraps off two intriguing concepts at the grand opening of its new advanced design centre in Pasadena, California. These are the GMC Hummer X ute and SUV concepts, which, while presented as experimental ventures, offer a tantalising glimpse into potential future directions for the brand.
Crucially, both of these concepts are significantly more compact than their existing Hummer EV brethren. The current GMC Hummer EV SUV measures a substantial 5.0 metres in length, while the Hummer EV Pickup Truck stretches even further to 5.5 metres. The new Hummer X concepts, however, are designed with a more accessible footprint, suggesting a potential shift towards a more versatile and perhaps even more utilitarian off-road offering.
GM has been clear that these concepts are “not intended for production” at this stage. Instead, they are positioned as a “testbed for new technologies, new aesthetics and new ways to build community around adventure.” This implies that their primary purpose is to explore innovative design philosophies, cutting-edge features, and novel manufacturing techniques, rather than to be immediate contenders for showroom floors.
A Niche in the Market?
Considering GM’s current lineup, there’s a notable gap in their portfolio for rugged SUVs and utes that sit below the considerable size of the Chevrolet Tahoe and GMC Yukon twins. These large, capable vehicles, while popular, occupy a different segment of the market. The introduction of something akin to the Hummer X concepts could very well fill this void, offering a compelling alternative to established players like the Jeep Wrangler and the Ford Bronco, both of which have carved out significant market share with their off-road prowess.
Hummer X SUV Concept: A Compact Contender
The Hummer X SUV concept presents a compelling package for those seeking a more nimble off-roader. It measures 4783mm in length, 1853mm in width, and stands 1853mm tall, with a wheelbase of 2946mm. These dimensions place it remarkably close to the Jeep Wrangler in terms of length and height, though the GMC is slightly narrower by 20mm and boasts a shorter wheelbase by 61mm.
This compact size, combined with short overhangs and an impressive 334mm of ground clearance, endows the SUV concept with formidable off-road geometry. It features a 44-degree approach angle, a 46-degree departure angle, and a 30.9-degree breakover angle. The vehicle rides on 18-inch beadlock wheels shod with burly 37-inch Goodyear 315/75 tyres, signalling its serious off-road intentions.
Hummer X Truck Concept: The Larger, More Capable Sibling
In contrast, the Hummer X Truck concept is a considerably larger proposition. It stretches to 5265mm in length, supported by a substantial 3319mm wheelbase. While still offering ample ground clearance at 316mm, its off-road angles are somewhat reduced compared to its SUV counterpart. The approach angle is 41.5 degrees, the departure angle is 29.7 degrees, and the breakover angle is 24.9 degrees.
This larger truck concept is fitted with 22-inch alloy wheels, wrapped in more road-biased 35-inch Goodyear 305/55 tyres. Both the SUV and Truck concepts share some key underpinnings and features, including Multimatic shocks for enhanced damping and extensive underbody protection to shield vital components from trail hazards. They also feature removable fender flares, adding to their customisable and rugged aesthetic.
Innovation in Design and Manufacturing
A standout feature across both concepts is the integrated “scout drone.” This small aerial vehicle can be deployed to fly ahead of the vehicle, scan the terrain, and transmit that data back to the car’s advanced, stackable display system. This technology could revolutionise off-road navigation, providing drivers with real-time insights into upcoming obstacles and optimal routes.
The concepts also showcase GM’s forward-thinking approach to manufacturing with the conceptual “Flex Fab” production process. This innovative method is designed to enable “fast, small-batch, on-demand production” of specific components, crucially without requiring expensive, specialised stamping tools. This could pave the way for more customisation and quicker iteration in vehicle development.
Sustainability has been a core tenet of the design brief. Many parts are engineered from single materials to facilitate easier recycling. Furthermore, these components are secured using mechanical fasteners rather than adhesives, simplifying disassembly and repair. Other elements, such as seat backs, headrest backs, and dashboard ends, are ingeniously crafted from recycled car bumpers. These parts are designed for effortless removal, swapping, and replacement, promoting longevity and customisation.
Adding a touch of personality and a nod to adventure, the floor mats are imprinted with Morse code, and the tyre tread is said to bear the message: “the courage to get lost leads to new discoveries.”
Powertrain Questions Remain
While both Hummer X concepts are presented as electric vehicles (EVs), GM has remained tight-lipped about specific performance figures. Details regarding power output, battery capacity, and estimated driving range have not yet been disclosed.
Given the recent trends in EV adoption in the US, particularly the tapering off of federal tax credits, it’s plausible that any future production version of the Hummer X concepts might also offer a traditional petrol-engine option to broaden its appeal and cater to a wider range of consumer preferences. This strategic move could ensure greater market viability for these intriguing off-road explorations.
