"GM's Chevy Volt plant in Detroit-Hamtramck is not your run-of-the-mill car factory."
Detroit-Hamtramck Assembly Of The Chevrolet Volt
"The 3.6 million sq. ft. facility with 1,600 workers makes five different models that all come off the same assembly line. Each car travels 16 miles inside the plant before completion."
Yes, that's right. The odometer on each vehicle rolls over 16 miles before its even left the building. No, that's not true.
Anyways, here's a look inside Detroit-Hamtramck Assembly, site of production for the Chevy Volt, Holden Volt, Opel Ampera and Cadillac ELR.
