The | The '''Chevrolet Sequel''' is a [[hybrid car|hybrid]] [[crossover SUV]] [[concept vehicle]] developed by [[General Motors]] and introduced at the 2005 [[North American International Auto Show]]. | ||
The Sequel is powered by a [[fuel cell]] [[powertrain]], which includes an electronic control unit and a fourth-generation version of GM's [[fuel-cell stack]]. A fuel-cell is an [[electrochemical]] device that combines [[hydrogen]] fuel with oxygen from air to produce electricity. The only waste by-product of that conversion is water vapor. | |||
The Sequel became the basis for the design of the [[Chevrolet Traverse]] which is the replacement for the [[Chevrolet Uplander|Uplander]] [[minivan]], which is being phased out. | |||
== | ==Characteristics== | ||
The Sequel's fuel-cell stack has a rated power output of 73 [[kW]] (98 [[horsepower|hp]]), supplemented by a [[lithium-ion battery]] pack rated at 65 kW. One 65 kW electric motor drives the front wheels and individual 25 kW wheel-motors (outboard of the rear brakes) drive each rear wheel, providing total tractive power of 115 kW. | |||
Although this may not sound like much power, electric motors have different characteristics from internal-combustion engines. Specifically, they achieve maximum torque at start-up. Consequently, according to GM's figures, the Sequel will accelerate from 0-to-96 [[km/h]] in less than 10 seconds — more quickly than a [[Hummer H3]] and well within the CUV/[[SUV]] norm. | |||
Hydrogen storage and, consequently, driving range are major challenges in the development of fuel-cell vehicles. The Sequel stores 8 [[kilogram|kg]] of gaseous hydrogen in three cylindrical, carbon-composite fuel tanks, pressurized to 700 [[Bar (unit)|bar]] (10,000 [[p.s.i.]]) and mounted longitudinally beneath the cabin floor. That is sufficient to provide an unprecedented range of more than 480 km between fill-ups, in spite of the vehicle's considerable 2,170-kilogram mass. | |||
The Sequel is just short of five-metres long (4994 mm), on an exceptionally long (3040 mm) wheelbase — the better to accommodate the extremely long fuel tanks. As a result, it is a very roomy vehicle, particularly in the rear seat. | |||
==Possible production== | |||
GM has made no commitment to building the Sequel. However, GM vice-chairman [[Robert Lutz|Bob Lutz]] has said he would push the company's strategy board to approve full production of a fuel-cell vehicle as early as the 2011 [[model year]]. However, due to the extremely high cost of fuel cells, GM opted to instead build several hydrogen-powered [[Chevrolet Equinox|Chevy Equinoxes]], as testbeds. It then decided to change it's direction of alternative-fueled vehicles, and showed the concept [[Chevrolet Volt|Volt]], followed by the production version a year later. As of October 2006, GM has built only two Sequels. | |||
