Good news. Yet the announcement was light on other important details—like when the car would go on sale, how many the company is producing (and how often a new car rolls off the line), and how many they plan to deliver this year. One thing CEO Ze'ev Drori did say: They plan to ramp production up to over 100 Roadsters per month by early 2009. Not enough to make much of a dent in total U.S. oil consumption, for sure, but perhaps enough to push battery technology forward to the point where a mass-market plug-in hybrid like the Chevy Volt becomes a reality. Here's hoping.
