A style of car that became popular in the US, which, while it makes a pretty good growl, manages to produce very little power, despite having 6+ litres of displacement. While they were very quick (and actually rather good looking and stylish in their own way) in the 60s and 70s, modern muscle cars are now left standing by Euro and Japanese cars (such as the supra, skyline, and BMW 3,5,6 series) of much smaller displacement, with more BHP and more BHP/Litre which also offer better fuel economy, better styling, and aerodynamics than their fat, sluggish, ugly, thirsty american counterparts.
The 69 Chevelle SS, 69 mustang, and C2 Corvette stingray are examples of great classic muscle cars, all very cool.

The 2008 Mustang managed to achieve a shocking 210 bhp from a 4.0l engine, America should be ashamed to claim that it is a performance vehicle, the Japanese get nearly 50% more than that from an engine half the size.
