Presentation Transcript

AUTOnomy is the “Reinvention of the Automobile” and is the first vehicle to be designed from the ground up around a fuel cell propulsion system and combining drive-by-wire control technology and electric wheel hub motors.

  • The GM AUTOnomy is a powerful vision of what the future of auto-mobility may become and as such offers an endless variety of all-wheel-drive vehicles built from a limited number of common “skateboard” chassis with unlimited plug-and-play body styles. The skateboards include all of the essential systems: a fuel cell stack, an electronic network, electric drive motors, and an on-board hydrogen storage system. The result is a vision of a future based on hydrogen fuel, a future where the only emission from the tailpipe is water.

With AUTOnomy, an almost endless variety of affordable, all-wheel-drive vehicles could be built from a limited number of common chassis - possibly as few as two or three - emitting only water from the tailpipe and using renewable energy.


POWER: Fuel Cells combine hydrogen and oxygen to produce electricity, with water and heat as the only by-products.  Hydrogen  is the most abundant element in the universe. 

  • CONTROL: Drive-by-wire allows steering, braking, and other vehicle systems to be controlled by electrical signals rather than mechanical joints and linkages.
  • SKATEBOARD: A six-inch thick chassis with the entire propulsion system housed within; wheel hub motors at the wheels enable four-wheel drive and four-wheel independent steering, acceleration, and braking; four electrical mechanical body attachment mounts to lock the body in place onto the skateboard; pre-configured and validated perimeter structural impact zones; external side mounted optimized cooling fins; a smart single access docking port to connect and link power, control, heating and cooling systems to the body from the skateboard; a refueling port for hydrogen, and an exhaust outlet dispersing water in the form of vapor.
  • MANUFACTURING: By decoupling the body and skateboard in the manufacturing process and using modular assembly and accelerated vehicle development techniques, millions of skateboards can be manufactured at one location to achieve economies of scale. The various bodies and body styles would then be built and customized at satellite assembly plants around the world for both emerging and established markets. This freedom and flexibility allows the vehicle to adapt to the needs of unique global markets,  changing lifestyles, and various customer requirements around the world.
  • BODY INTERCHANGEABILITY: The body of an AUTOnomy vehicle can be tailored to a manufacturer type, to a desired interior vocabulary, and to any exterior form or desired style. 
  • SOFTWARE CUSTOMIZATION: The body and skateboard are programable and customizable and can learn from and adapt to the user. Software--in combination with hardware--can adapt to a user or be pre-conditioned for certain driving characteristics, such as braking, cornering and acceleration.
  • UNVEILING: Revealed January 2002 at the North American International Auto Show (NAIAS). The General Motors AUTOnomy body has a futuristic two-seat roadster body (one of many possible interchangeable body styles) inspired by motorcycle and fighter jet designs. 

It looks like an ordinary Opel Astra, one of Europe’s most popular compact sedans. But slip into the driver’s seat and you quickly realize there’s something a bit unusual about this high-tech prototype. The oddly shaped steering wheel is probably the first clue, though the lack of foot pedals is a definite giveaway. The particular Astra TheCarConnection had the chance to drive at California’s Buttonwood racetrack uses the latest in so-called “drive-by-wire” technology, and could very well be a sign of things to come.


Named for its combination of hydrogen fuel cell and drive-by-wire technology, the Hy-wire incorporates the features envisioned in the AUTOnomy concept vehicle. All of its propulsion and control systems are contained within an 11-inch-thick skateboard-like chassis, maximizing the interior space for five occupants and their cargo.

Overview: The Sequel, about the size of a Cadillac SRX, is the first fuel cell vehicle that achieves 0-60 mph in under 10 seconds and has a 300-mile range. Unequaled control on snow and ice, or uneven terrain. 42-percent more torque for unparalleled acceleration. Shorter braking distance than an equal size vehicle

Sequel’s sophisticated by-wire system replaces the mechanical and hydraulic linkages of conventional vehicles with electrical wires and actuators. This means fewer parts to wear out, and because by-wire systems work like a fast computer, Sequel has enhanced accelerating, braking and overall handling.
