Video walk through of the Volt. (she says "intuitive" a lot. A visual tour of the GM Volt, electric cars | Green Tech - CNET News
There is a bit of other EV news.
Interesting that it has a 400 lb battery but only goes 40 miles compared to a 900 lb Roadster bat goes 200 miles.

That's because the Volt only uses half of its capacity. Also, since the pack is small, it will have to sustain high discharge rates. That means it has to be optimized for power density (which trades off with energy density)

Does anyone know the weight of the Volt? I bet it is more than 2700 lbs. | |

Even so $750 million to make a car still looks like a lot compared with Telsa's $140 million. I wonder if the price they are reporting now as opposed to earlier is because it is true, or because they needed to look better to try and receive the loans? | |

General Motors has put the brakes on construction of a $349 million plant slated to produce engines for the extended-range electric Chevy Volt and compact Chevy Cruze in Flint, Mich. by 2010. According to the Flint Journal, preliminary surveying, property security, and underground work on the site has already been done since GM unveiled plans for the plant less than three months ago.
“It’s temporarily on hold as we assess our cash situation,” GM spokesperson Sharon Basel told the Detroit Free Press today. “I don’t think it’s a surprise that we’re studying and reviewing everything given the position we’re in.” Nor would it be a surprise if GM is using the Flint plant for leverage in its emergency loan negotiations with the White House, as suggested on the GM-Volt blog today:
