Ultimate Factories: Dodge Viper

Detroit's only hand built production car, the Dodge Viper, is born, bred and built in Detroit, Michigan. National Geographic takes a unique insiders look at the Viper factory in the current models last year of production. This ultimate factory is comprised of craftspeople who spend two and a half days building each Viper, which is packed with 600 horsepower that can take it from zero to 60 mph in under four seconds. Without any robots on this assembly line, every Viper is truly hand crafted. Priced at half of the cost of Ferraris and Lamborghinis, only 26,000 Vipers have hit the road in 18 years.
