Chevrolet Sequel

The Chevrolet Sequel is a purpose-built hydrogen fuel cell-powered concept car and sport utility vehicle from Chevrolet, employing the then-latest generation of General Motors' fuel cell technology.
The Sequel's powertrain included an electronic control unit and a fourth-generation version of GM's fuel-cell stack. The Sequel became the basis for the design of the gas-powered Chevrolet Traverse, which was the replacement for the Uplander minivan.

Characteristics

The Sequel's fuel-cell stack had a rated power output of, supplemented by a lithium-ion battery pack rated at. One electric motor drove the front wheels, and individual wheel-motors drove each rear wheel, providing total tractive power of.
The Sequel stored of gaseous hydrogen in three cylindrical, carbon-composite fuel tanks, pressurized to and mounted longitudinally beneath the cabin floor. As a result, the range of the vehicle was more than.
The Sequel was just short of five metres long, on a similarly long wheelbase in order to accommodate the extremely long fuel tanks.

Possible production

GM made no commitment to building the Sequel. However, GM vice-chairman Bob Lutz has said he would push the company's strategy board to approve full production of a fuel-cell vehicle by 2011 model year. Due to the extremely high cost of fuel cells, GM opted to instead build several hydrogen-powered Chevrolet Equinox-based vehicles as testbeds. It then decided to change its direction of alternative-fueled vehicles, and unveiled the concept Volt in 2008, followed by the production version in 2010. As of October 2006, GM has built two Sequels.
