"the curves of Corvette"?

Nope - they pretty much lifted the design cues from the Saab Aero-X.

Don't look for Big Auto to change the status quo anymore than it did after the first oil crunch in 1973. While GM gushes on about fantasy concept cars, the Tesla Roadster is already here.

Hells bells, who's in bed with the big, bad wolf:
The Sierra Club espouses hybrids, "...each gallon of gasoline burned pumps 28 pounds of CO2 into the atmosphere, the average car emits about 63 tons of CO2 over its lifetime. If all of the vehicles in the US averaged 40 miles per gallon we would save over 3 million barrels of oil each day; that is more oil than the United States currently imports from the Persian Gulf and could ever extract from the Artic National Wildlife Refuge, combined." In conclusion, the answer they stand behind is that "Innovative technology can help free us from our dangerous oil dependence."
And found on the Green Peace USA web-site is your average house wife Sally, who sallies forth to gush about how hybrids are "...everything we had imagined and a little more. We are the proud owners of two hybrids." Meet Heather--an environmental consultant--and her husband Dave--a research scientist--and find out how they "...love our hybrids and can't imagine driving any other type of car. It is such a small price to pay to encourage technology that will help us reduce the amount of pollutants we are contributing each year to the global warming epidemic."
Still..., don't you just love how BP Exploration (Alaska) Inc. made a sweetheart deal with Alaska Governor Tony Knowles to develop Northstar oil field. Of course, the project was put hold after a lawsuit was filed by several Anchorage residents who argued that the deal was only sugar-coated..., before "the Supremes" got into the act and predictably sided with the state in a 1998 decision. Some North Slope Natives also challenged the the developement in court, alleging that the Environmental Impact Statement for the project was inadequate, and that BP didn't have an adequate oil spill response plan for the project. Yet, alas, that big, dirty, old Ninth Circuit ruled against the indians running scared. On the one hand, the uS Army Corps of Engineers noted that the "Calculated total probability of one or more large spills (greater than 1,000 barrels) from any source is approximately 11% to 24% over the 15-year project life," while, on the other hand, although pipelines are normally monitored once a week, Northstar is monitored only once a month--and this by drilling randomly through ice in conditions of near-darkness, such it's likely that any leak which occured in winter would go unnoticed until spring--if even then!
Currently, electric cars can travel 180 miles per charge... So..., exactly why haven't the automakers gotten around to developing cars with quickly replaceable battery packs...
Why not actualize electric cars that travel on an electric grid that's laid right into the well drained lanes of all freeways and highways, And the great thing about this concept is that it would be easy to switch over all existing cars... Simply install a small battery fro around town, and than for longer commutes, ect., one would just get on the freeway..., which would charge up the battery at the same time!

Plugs on cars could provide the best way to reduce CO2 emissions, lower petroleum dependence, and reign in the montrous oil companies by giving consumers a choice. Whether GM means it is still up in the air. My blog follows these issues closely. Check it out. www.plugsandcars.blogspot.com

Regarding:
"GM killed off its previous electric vehicle."
Right. GM stopped producing it because people weren't willing to pay for it. Please note that Toyota and Honda didn't even try to produce an all-electric vehicle because they knew customers weren't interested (in large enough numbers to make it worth it).
Also, please note that the reason GM went all-electric with the vehicle was because it was mandated by the CA regulators. The CA regulators backed off of the regulations when they realized how difficult it was to do successfully. Gotta love gov bureaucrats. Reminds me of old Stalinists times..
Please stop with the GM bashing.

Watch "Who Killed The Electric Car." GM, et all NEVER wanted the electric car to suceed, made it difficult/ near impossible for regular people to get and even when people were willing to pay thousands to buy one after the recall chose to crush them instead.

American automakers wonder why consumers are looking abroad? Look no further than stunts like the EV (Although Toyota was with them on that fiasco). Hmmm... wonder when this wonderful GM hybrid will be available... probably the same time there's a car that can fold up into a briefcase.

The Volt concept car is not a plug-in hybrid... it runs ONLY on electricity. The gas engine never drives the wheels directly... it's just a back-up power generator.

The energy to run a car has to come from somewhere, whether that is a gas pump or an electrical wall plug. The energy content of gasoline, converted to electrical units, is equal to about 31 kilowatt-hours per gallon. Looking at my summertime electric bills, I paid a "baseline" rate of 17 cents per KWH for a parsimoneous "baseline" allocation of electricity, and up to 36 cents per KWH for "more than 200% over baseline" power. So powering my car from a wall plug would cost me the equivalent of paying $5.27/gallon for gas to run a gas-powered car, even at the "baseline" electricity rate, and up to $11.16/gallon equivalent for the marginal rate if I added car-powering to my electricity consumption in summertime. One might imagine electric companies or governments offering subsidies for electricity to power electric cars, but inconceivably to less than 10 cents per KWH, which would actually lose money compared to the cost of generation and at the same time be equivalent to paying $3.10/gallon at the pump. Add to all that the fact that energy is energy and a fossil-fuel fired electric power plant uses as much fuel and produces as much waste gases as an automobile on the road, per unit of energy delivered to the wheels, and you can easily understand why the plug-in car is a loser, regardless of whether automakers or governments love them or hate them.

Here is an interesting article on why vehicles will continue to require gas vs electric ... fuel taxes feed infrastructure needs http://money.cnn.com/magazines/fortune/fortune_archive/2004/01/26/358835/index.htm
