The National Geographic Channel, available on cable and satellite TV systems, tells all about the Audi R8 on an episode of Ultimate Factories that airs at 10 p.m. Eastern. The show takes views into Audi's assembly plant in Neckarsulm, Germany, where workers build up the R8's aluminum spaceframe by hand.

Just prior to the Audi episode, the channel airs an episode of Man Made devoted to building the Veyron. From the factory in Molsheim, France, that bolts three sections together to form a car to the engine plant in Germany that builds the 1,001-hp W16 engine, we get a close look at this much-lauded car. The Veyron episode starts at 9 p.m. Eastern.

Need more assembly mania? Tune in an hour earlier, at 8 p.m. Eastern, for an episode of Ultimate Factories devoted to the John Deere operation.
