Chevrolet Sequel (2006)

SAN DIEGO (Sept. 11, 2006) GM Motors today announced a driveable version of the most technologically advanced automobile ever built the Chevrolet Sequel, GM's solution to provide the world with a cleaner, petroleum-free vehicle that is better in nearly every way.

"General Motors is proving that advanced technology can remove the automobile from the environmental debate and reduce our dependence on petroleum," said Larry Burns, GM vice president, research & development and strategic planning. "Chevy Sequel clearly shows that our vision for the future of the automobile is real and sustainable."

Sequel was introduced in 2005 at the North American International Auto Show in Detroit. It is the first vehicle in the world to successfully integrate a hydrogen fuel cell propulsion system with a broad menu of advanced technologies such as steer-and brake-by-wire controls, wheel hub motors, lithium-ion batteries and a lightweight aluminum structure. It uses clean, renewable hydrogen as a fuel and emits only water vapor.

"Sequel fundamentally changes the DNA of today�s automobiles exchanging an internal combustion engine, petroleum and mechanical systems for fuel cell propulsion, hydrogen and electrical systems," Burns said. "In Sequel, GM has created a real vehicle that promises to excite customers and lead to long-term, sustainable automotive transportation."
