Opel Ampera on the Volt?s heels

The Opel Ampera passed an important milestone Friday, April 23, when the first pre-production Model Year 2012 Ampera rolled off the line at GM?s Pre-Production Operations assembly line in Warren, Michigan. Assembly workers will build more pre-production Ampera?s in the coming months. These pre-production vehicles will not be sold at dealerships, but used instead for testing and validating the production intent design as well as developing the final vehicle software and controls.
