Legendary drivers lead us on a record-breaking race through a century-long search for sheer acceleration that began before World War One, when hot-rodders modified Model-T Fords to see how fast they could go. Today's dragsters can cover a quarter-mile from a standing start in four-and-a-half seconds, hitting top speeds above 330 m.p.h. Top driver Gary Clapshaw shows us how to put together a modern dragster and revolutionary designer Bob Norwood unveils his newest car.
