The bold push from General Motors Corp. to reinvent the automobile, first revealed in the AÚTOnomy and Hy-wire concept cars, became that much more real today wîth the unveiling of the GM Sequel.

The technologies embodied in Sequel, such as fuel cells, by-wire and wheel hub motors, have developed so fast that GM has been able to double the range and halve the 0-60 mph acceleration time, compared to current fuel cell vehicles, in less than three years, according to Larry Burns, GM vice president of research and development and planning.

'Three years ago, our chairman and CEO, Rick Wagoner, challenged us to completely rethink the automobile,' Burns §äid. 'The Autonomy and Hy-wire concepts were the outgrowth of that challenge – a revolution in how vehicles would be designed, built and used in the future. But, they were concepts. Today, wîth Sequel, the vision is real – not yet affordable, but doable.'

Sequel embodies GM's vision of reinventing the automobile wîth a fusion of technologies that includes advanced materials, electronic controls, computer software and advanced propulsion. According to Burns, it's an exclamation point for GM's comprehensive global advanced technology strategy that is addressing efficiency and emissions, from today's engine and transmission technology to hybrids and, eventually, fuel cells as the ultimate answer.

'GM's goal,' Burns explained, 'is to design and validate a fuel cell propulsion system by 2010 that is competitive wîth current internal combustion systems on durability and performance, and that ultimately can be built at scale affordably. '

What excites Burns is that Sequel's performance is achieved wîth technology available today and does not depend upon some science yet to be invented.

'We've achieved remarkable gains in range and acceleration by using our fuel cell system technology that exists today,' Burns §äid. 'That's a real breakthrough. For anyone tracking the viability of fuel cell vehicles, this is encouraging news.'

Sequel, about the size of a Cadillac SRX, travels up to 300 miles on its hydrogen supply, and accelerates to 60 mph in less than 10 seconds. Current-generation fuel cell vehicles have a range of between 170 and 250 miles and cover 0-60 mph in between 12-16 seconds, depending upon whether a battery is used.

'With Sequel,' Burns said, 'virtually everything is packaged in an 11-inch ‘skateboard' chassis, building on what we first showed the world in the AÚTOnomy and Hy-wire. Sequel points to a vehicle that, in the future, will be better in nearly every way – quicker, surer-footed, easier to handle, easier to build, better lòòking, safer and only emits water vapor.'

Other benefits include:

Únequaled control on snow and ice, or uneven terrain

42-percent more torque for unparalleled acceleration

Shorter braking distances

While Sequel should excite customers, it also should encourage world governments, Burns added, because of its potential to address societal concerns.

'Sequel helps address major societal issues, from eliminating auto emissions, to helping the world transition to renewable and stable energy supplies, to reducing the chance for crashes and traffic congestion,' Burns §äid.
