Chevy Volt in Transformers 201/09/2008
Perhaps the most telling detail though is the visible at the base of the A-pillar right in front of the mirror.
The letters on that badge sure appear to spell out VOLT!. The car in this photo was shot during filming of Transformers 2 somewhere in Long Beach. So far calls to our contacts at GM are going unanswered but let you know as soon as we hear something. Thanks to Tony for the tip!
UPDATE: This is indeed the Volt! A video of the shoot has turned up that shows the car from above and clearly shows the rear end with a Chevy bowtie badge and prominent Volt logo. You can check out the video here and screen caps in the gallery below.
