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.
