After suffering what must be called the worst five years of American car design 1974-1979, the 1980s ushered in the beginning of a new generation of performance cars. Chevrolet showed up first with the ground-breaking Corvette in 1984, followed by a series of performance cars leading up to the Buick GNX, the IROC Camaro, Mustang SVO, and several other cars that launched a second muscle car revolution. A revolution, that has arguably continued into the 21st century.
