General Motors Corp. showed off the so-called “skateboard” for its Chevy Sequel technical concept vehicle at SAE’s 2007 World Congress this week. The vehicle, which GM calls the “most technically advanced automobile ever built,” was said to represent the third stage in the automaker’s “Reinvention of the Automobile” program.”
Designed around hydrogen fuel cell technology, the Sequel uses three electric motors and a lithium-ion battery for its propulsion system. The vehicle reportedly has a 300-mile range between hydrogen fill-ups and emits only water vapor.
Late last year, GM announced that it had created the first driveable version of the vehicle.
The so-called “skateboard” shown at SAE this week is an 11-inch-deep chassis that contains all of the Sequel’s propulsion, transmission, steering and braking components and provides a single electrical connection to its body.
