The General Motors Hy-wire Concept, introduced in January 2002, represents a groundbreaking approach to automotive design and propulsion. Running on hydrogen fuel cells and utilizing a sophisticated drive-by-wire system, the Hy-wire concept reimagines the traditional car layout, offering unparalleled flexibility and adaptability.
The design of the Hy-wire concept is centered around its hydrogen fuel cell drive system, which eliminates the need for a conventional engine block and transmission system. Instead, all propulsion and energy storage components are integrated into a flat skateboard configuration. This innovative layout not only lowers the car's center of gravity but also standardizes vehicle drive train systems, paving the way for modular vehicle configurations.
By housing the power system and electric motor in the skateboard, designers have the freedom to arrange the passenger compartment in various configurations, such as a 4-door sedan, mini-van, or small bus. The only differences lie in the shape of the car's upper body and the seating arrangement, while the skateboard remains consistent across models. Additionally, the skateboard incorporates crumple zones for enhanced safety, similar to conventional automobiles.
The Hy-wire's drive-by-wire system, coupled with cameras replacing traditional mirrors and multiple LCD displays, offers an advanced driver interface. This system theoretically allows the driver's seat to be located anywhere within the vehicle, although current designs often place the driver in a position for optimal visibility. The controls, including steering and throttle, are not fixed in place, enabling flexibility in seating arrangements. For example, some models feature a single control interface operable from either the right or left front seats, while others utilize rotating platforms to swap the positions of the driver and passenger seats.
Powering the Hy-wire is a fuel cell capable of producing 94 kilowatts of continuous power, with a peak output of up to 129 kilowatts for short durations. Hydrogen, supplied from three tanks of compressed hydrogen located in the chassis, fuels the fuel cell. With its three-phase electric motor, the vehicle, weighing 1,814 kg (4,000 lb), achieves a top speed of 160 km/h (100 mph).
Overall, the General Motors Hy-wire Concept represents a visionary approach to sustainable and adaptable transportation, leveraging hydrogen fuel cell technology and innovative vehicle architecture to redefine the driving experience.
