GM goes electric with new concept car at auto show

DETROIT (Reuters) - Struggling auto giant General Motors Corp. on Sunday revived its once-failed idea of a mass-market electric car, unveiling a new "concept" car called the Volt designed to use little or no gasoline.

Introduced at the North American International Auto Show here, the Chevrolet Volt will draw power exclusively from a next-generation battery pack recharged by a small onboard engine -- if the technology is ready in two or three years.

"We have a thoroughly studied concept, but further battery development will define the critical path to start of production," said Jon Lauckner, a GM vice president for product development.

The Volt is designed to run for 40 miles on pure electric power, making it marketable for everyday family use.

For the average American driver who drives 40 miles a day, or 15,000 miles a year, the Volt will require no fuel and lead to an annual savings of 500 gallons of gasoline, GM said.

Unlike current gas-electric hybrids, which use a parallel system twinning battery power and a combustion engine, the Volt will be driven entirely by electric power.

GM has been stung by criticism that it conspired to kill the EV1, an experimental electric vehicle program it launched in 1996 and killed by 2003. The documentary film "Who Killed the Electric Car?" released last year criticized GM for first developing but then abandoning electric vehicles.

GM said the Volt will have advantages over the defunct EV1, including smaller batteries, faster recharging, more room for passengers, and a faster maximum highway speed.

"For most drivers, the Volt will use little or no gasoline," GM chief engineer Nick Zielinski told reporters.

FIGHTING TO GET "GREEN" -- AND TOYOTA?

The Volt is part of GM's bid to demonstrate it is investing in break-through technology with some of the $9 billion saved through a wrenching program of job cuts and plant closures.

The push to develop environmentally friendly cars is also an attempt by GM to distance itself from its close association with gas-guzzling sport utility vehicles, a reputation executives say has hampered its sales in some markets.

The Volt's combustion engine is designed only as a supplement to keep its batteries charged, an innovation GM executives hope will help the automaker jump ahead of Toyota Motor Corp., which now dominates the hybrid market.

GM cut 34,000 jobs last year and plans to close 12 plants. Toyota is expected to surpass GM in global production this year, ending a run of more than 80 years for GM as the world's No. 1 automaker.

In November, GM Chief Executive Rick Wagoner used a speech at the Los Angeles Auto Show to announce that GM would build plug-in hybrid vehicles, a potential industry first.

Plug-in hybrids, a favorite among many environmentalists, are capable of being charged with a standard electric outlet.

Battery technology is key to the next generation of hybrid vehicles as automakers seek ways to lower the cost of batteries and increase their power and storage capacity.

The Volt will be outfitted with new lithium-ion battery packs, which hold a charge longer than the nickel metal hydride batteries now used widely in automobiles.

Lauckner said the Volt should be ready for production around the same time the lithium-ion batteries will be, which GM expects to be in two to three years.

Automakers have been cautious that lithium-ion batteries, which are now used in consumer electronics such as laptop computers, have a tendency to overheat.

But GM also plans to introduce hybrid systems in its Saturn Vue, Saturn Aura and Chevrolet Malibu cars and in its Chevrolet Silverado and GMC Sierra trucks.

Last week, GM awarded lithium-ion battery development contracts for its Saturn Vue Green Line hybrid to Johnson Controls Inc. affiliate Johnson Controls-Saft Advanced Power Solutions and Cobasys, a venture of Chevron Corp. and Energy Conversion Devices Inc.. Cobasys will work with privately held A123Systems to develop the technology.

"We're not going to see huge changes in 10 or 15 years," says Marc Ross, professor emeritus of physics at the University of Michigan who has focused on automotive technology. "You can't really change the fuel in that kind of time span. It takes time. It takes huge investments. We have almost 200,000 gas stations. The only fuel you could change in a time like 10 or 15 years is to add ethanol, to adopt a mixture that can be served from the same gas pumps. But if you want to do something different, like hydrogen -- hydrogen is very difficult to handle -- that's going to take a great deal of time."

Cita de: Daniel

Escéptico, formalmente, y por el poder de Greyskull al que invoco y me da plenos poderes de abofetear el MySQL 5.0, te ofrezco cambiarte el nick por "Optimista", o la fórmula que tu elijas que incluya el término "optimista".

Cita de: windguruDaniel, el poder de Greyskull (de Calavera grisa en la traducción que daban en TV3 durante mi juventud) permite modificar el nick sin perder el curriculum forero? es que tengo un problema con mi nick, muy curioso, mirad esa página:

WindGURU: United States - Maui (north shore)

Pues bien, no se de donde saca la gente mi mail pero me piden... ¡¡¡previsiones de viento en la playa!!! yo no tengo nada que ver con esa página, es una coincidencia!
Tengo miedo que me metan una demanda o similar por plagio, aunque no creo, es un plagio totalmente inconciente sin ánimo de lucro.

Si el poder de Greyskull permite eliminar el "Guru" y dejar mi nick en "Wind" supongo que evitará problemas, durante unos dias pondria la conversión en la firma para evitar confusiones, sinó es posible o implica perder mi curriculum seguiré haciendo previsiones de viento sin problemas...

Saludos.
