Ultimate Factories: Mercedes Benz

Go inside Mercedes' largest German factory to see what it takes to build the 571-horsepower Mercedes SLS. Computers control everything in a Mercedes with more than a mile of wiring in each car, but to create the fastest Mercedes to date topping out at 197 mph it takes some of the best engineers in the world to mold a light yet strong supercar in 15 hours. The spiritual successor of the original 1950s Mercedes 300 S-L, the $183,000 2010 SLS blends modern engineering with classic Mercedes design.
