The final batch of pre-production Chevrolet Volts has been built in the US, as extensive development work on the range-extender hybrid continues.
The last of the 80 development models has rolled off GM's assembly line in Warren, Michigan and the car will now be subjected to rigorous testing at the Milford Proving Grounds in the US.
Bob Warner, GM’s director of global pre-production operations, said: “The 80 vehicles we built are now entering the next stage of development.
“This includes a series of crash tests, developmental drives, battery checks, climate tests and other measures we take to make sure the production vehicles meet our high standards.”
GM also said it planned to build between 2000-3000 production versions of the Volt in 2010 and sales are set to begin late next year. The European version, the Vauxhall Ampera, is expected to follow in 2011.
