2002 GM Autonomy Concept



The GM Autonomy Concept, unveiled in 2002, represents a groundbreaking leap in automotive technology, being the first vehicle designed entirely around a fuel cell propulsion system and integrating drive-by-wire technology. This innovative combination enables steering, braking, and other vehicle systems to be controlled electronically, heralding a new era in automotive design and efficiency.


Larry Burns, GM Vice President of Research and Development and Planning, highlighted the transformative potential of the Autonomy concept. By leveraging fuel cell propulsion and drive-by-wire technology, GM envisioned a future where an array of affordable, all-wheel-drive vehicles could be constructed from a small number of common chassis. These vehicles would emit only water from the tailpipe, representing a significant advancement in environmental sustainability.


The fuel cell propulsion system utilized in the Autonomy concept offers exceptional efficiency, approximately double that of traditional internal combustion engines. This heightened efficiency potentially doubles the fuel efficiency of comparable conventional vehicles. Moreover, the optimized design of the Autonomy concept suggests even greater efficiency gains, with projections surpassing 100 miles per gallon gasoline equivalent for a full-size car.


At the heart of the Autonomy concept is its skateboard-like chassis, which houses all essential components. This innovative approach eliminates the need for foot pedals, instrument panels, and steering columns, allowing for unparalleled flexibility in vehicle design. With these traditional elements removed, the driver is free to sit anywhere within the vehicle, enhancing comfort and customization.


Inside the vehicle, traditional foot pedals are replaced by a hand-operated steering guide known as the X-drive. This innovative control mechanism, reminiscent of aircraft and motorcycle controls, streamlines the driving experience and maximizes interior space.


Christopher Borroni-Bird, head of GM’s Design and Technology Fusion Group, emphasized the versatility of fuel cell technology. Unlike internal combustion engines, fuel cell stacks can be distributed throughout the vehicle, offering designers unprecedented freedom in shaping vehicle architecture. The compact design of GM's HydroGen III fuel cell system, adapted for use in the Autonomy concept, further optimizes space utilization.


The Autonomy concept represents a bold vision for the future of automotive transportation, leveraging cutting-edge technology to redefine the driving experience while prioritizing efficiency and sustainability. As advancements in fuel cell technology and vehicle design continue, concepts like Autonomy pave the way for a more innovative and environmentally conscious automotive industry.
