A group of police that drive fast, un-marked cars(usually impounds) such as Mustangs, Corvettes, Chargers, or even exotics such as Ferrari's, Porches and Lamborghini's.
Their main purpose is to catch speeders and street racers, though they will often assist other officers during traffic stops, accidents or spot checks.
Though many jurisdictions have used impounded sports cars as special duty patrol cars, the Wolfpack has its origins with the Tampa Police Department. They were the first department to specifically assign such vehicles to select officers with specific orders to target speeders.
Think twice before you race that mustang, he might be in the wolfpack.
