The Straight Dope is an exhaustively researched newspaper column, book series and website dedicated to giving detailed answers to just about any question that people can think of (take a look through the archives and you'll see that it really is any question, even if it could be considered extremely taboo).

Anyway, in the latest newsletter, there was a question regarding the difference between horsepower and "torques," as Jezza likes to call them.
