"Fastest Car" tries to find out if tricked-out "sleeper" cars can keep up with exotic supercars that are known for their speed. The sleeper cars are built and modified by true gearheads before being put to the test against the supercars that are piloted by drivers who put their street cred on the line in the automotive battles. In each episode, three souped-up cars that have been lovingly labored on go head-to-head with one of the world's most sought-after vehicles. Among the matchups featured on the series are a 2011 Pontiac minivan going against a Porsche GT3.
