Street racing in the U.S. is the subject of this docu-reality series, which purportedly provides an inside look into the action both on the road and behind the scenes. In Oklahoma City, for example, racers boast having the fastest street cars in the country, and the racing, they say, comes first -- before family, before friends and before work. From a 1969 Chevy Nova to a race-ready farm truck, the vehicles -- and their drivers -- come in all shapes and sizes and have one thing in common: the need for speed.

"Street Outlaws" gained traction with viewers by glamorizing activities on the road and behind the scenes of street racing enthusiasts in Oklahoma City. Now, with underground leagues "exploding across the country and taking new forms," says Discovery Channel, the network expands its docuseries to focus on fledgling teams in New Orleans. Following the pavement scorched by their Midwestern brethren, street racers in the Big Easy band together to prove they are the fastest in the country.

Discovery Channel takes viewers inside the world of underground truck racing. In "Dirty Mudder Truckers," a crew of racers in Central Florida called the Dirty 7 gets down and dirty in The Pit facing challengers and pushing their machines to the limit. Each week, a different crew heads down to Central Florida to take on the Dirty 7 in The Pit, a 750-foot stretch of mud with a 10-foot tabletop jump. The crews battle it out in head-to-head grudge matches to see who will come out on top, take home the cash prize and earn bragging rights as the best crew out there.
