DETROIT, MI - The first Chevrolet Volt rolled off the assembly line at General Motors' Detroit-Hamtramck Assembly plant in November 2010.
We took a first-generation, 2013 Chevy Volt and a new, 2016 model back to the place where they were first assembled to compare what's new and improved on the plug-in electric car:

We'll have more information on the 2016 Chevrolet Volt later in the week.
And to be clear, not every single piece of the Volt is built at the Detroit-Hamtramck plant, which straddles the Detroit and Hamtramck border.
The new Volt's drive unit is manufactured at GM's Powertrain plant in Warren, and the 1.5-liter engine is built at a GM plant in Toluca, Mexico. However, after the first year of production GM will be switching engine sourcing to its Flint, Mich. engine plant.
The 4.1 million-square-foot Detroit-Hamtramck plant was opened in 1985. It employs about 1,600 workers, including 1,400 hourly and 200 salaried.
GM invested $336 million in 2009 to upgrade the plant for production of the Volt, and spent another $384 million in 2014 for production of the all-new, next-generation Volt, as well as for the Cadillac CT6 sedan.
GM also assembles the Chevrolet Malibu, Impala and Cadillac ELR at the site.
