General Motors has unveiled the GMC HUMMER X concept alongside the opening of its new Advanced Design studio in Pasadena, California, presenting a pair of electric vehicle concepts intended to explore future design, manufacturing and mobility ideas.
The concepts, which include both truck and SUV body styles, are not planned for production and serve primarily as design studies developed by the company’s advanced design and engineering teams.
New Pasadena Design Campus Opens
The GMC HUMMER X made its debut at GM’s new 148,000-square-foot Advanced Design campus in Pasadena.
The facility spans three buildings and houses approximately 100 employees, including designers, sculptors, fabricators and digital development specialists.
According to General Motors, the studio will focus on long-term concept development and future mobility exploration rather than current production vehicle programs.
Bryan Nesbitt, vice president of Global Design at General Motors, said Southern California continues to play an important role in shaping future vehicle concepts.
“Southern California isn’t just a place where we work, it’s a place of unfiltered inspiration,” Nesbitt said.
“These sources of inspiration influence how our designers see the world to envision what mobility could offer 10 or 20 years into the future.”
Four Design Themes
GM said the HUMMER X concept was developed around four primary themes: reconfigurability, capability, community and sustainability.
The project was created through collaboration between GM Advanced Engineering, Advanced Manufacturing and the Pasadena design team.
Brian Smith, who previously led the Pasadena studio, said the design process was guided by an outdoor exploration philosophy.
“Every great concept starts with a belief,” Smith said.
“The team rallied around a working mantra of ‘Take nothing but pictures, leave nothing but footprints,’ and let that philosophy guide every decision.”
Exploring Flexible Manufacturing
A key element of the concept is a manufacturing approach called FLEX FAB.
General Motors describes FLEX FAB as a flexible metal fabrication process designed for small-volume production without the need for dedicated stamping tools.
The company said the approach enables multiple component designs to be produced using the same manufacturing equipment.
According to GM, approximately 57% of each HUMMER X concept was produced using the FLEX FAB process.
The manufacturing method contributed to the vehicle’s distinctive design, featuring flat surfaces, rounded edges, laser-welded seams and exposed fastening elements.
Off-Road-Oriented Design
The HUMMER X was conceived as a mid-size electric vehicle focused on off-road capability.
Features include:
- Up to 37-inch Goodyear tires
- Beadlock wheels
- Multimatic suspension dampers
- Removable fender flares
- Underbody protection systems
- Up to 13.2 inches of ground clearance
GM said the electric platform’s low center of gravity and instant torque characteristics support off-road performance objectives.
Connected Community Features
The concept also introduces a digital ecosystem known as HUMMER HUB.
The proposed system includes connected applications designed to support vehicle customization, community engagement and outdoor exploration.
Among the concepts presented is a scout drone capable of flying ahead of the vehicle, gathering terrain information and transmitting data back to the vehicle in real time.
Sustainability Concepts
GM incorporated several sustainability-focused ideas into the HUMMER X design.
The vehicle utilizes mono-material construction strategies in selected areas and reduces the use of adhesives in favor of mechanical fasteners and snap-fit components.
According to the company, these design choices are intended to simplify future recycling and component replacement.
Several interior components, including seatback panels, headrest backs and dashboard trim elements, were produced using recycled vehicle fascia materials.
The concepts also feature components designed for easier removal and replacement, supporting future reuse and material recirculation strategies.
Part of GM’s Global Design Network
The Pasadena facility joins General Motors’ global network of advanced design studios, which includes locations in Detroit, the United Kingdom and Shanghai.
GM said the new campus will serve as a center for experimental vehicle development and future mobility research as the company continues exploring next-generation transportation concepts and technologies.
