Live Webcast: General Motors product and technology update at 8AM Eastern

General Motors CEO Fritz Henderson will make a presentation this morning at 8:00 AM EDT from the GM Tech Center in Warren MI. One month after exiting bankruptcy, Henderson will update the media on GM's progress so far, as well as make some product announcements, which were previewed yesteday during a similar presentation to social media users as part of a deftly-executed viral campaign. Among the announcements expected today is Chevy Volt-related news that formally explains the cryptic "230" hint discussed last week. Bloomberg reports this morning that the number represents the Volt's EPA city fuel economy rating-- as in 230 mpg. We'll be on hand in Warren for the briefing, and you can watch the announcement live yourselves via webcast at 8AM Eastern after the jump.
