Chevrolet Monte Carlo SS
Chevrolet not only again called upon GM Motorsports for design inspiration, but also to Monte Carlos of the past. Among the traits carried over from older Monte Carlos were the stylized wheel flares, vertically oriented tail lamps, and a stylized rear bumper. Another classic trait for 2000 was the return of the "Knight" badging, as well as a full gauge cluster, not seen on the Monte Carlo since 1988. Back again was the Super Sport moniker, replacing the Z34 designation of the Fifth Generation, which was a Lumina Coupe legacy. At the request of racing teams, Chevrolet stylists added a slight "hump" on the rear trunk - similar to, although smaller than, a Lincoln Mark. It was a distinct trait that stayed with Monte Carlo until its demise, even though later in the generation every trim level would get a spoiler that all but masked the hump. From the NASCAR circuit came the aerodynamic styling and duck tail spoiler.
