20. Jaguar XKR
Jaguar was always known for its line of perfect GT coupes and convertibles with luxury appointments and power. But from 1996 to 2006 XKR coupe is a proper muscle car. Under the sleek body and acres of finest leather lies a supercharged V8 engine delivering 370 HP and a brutal performance.
Also, the XKR is a bit different than regular XK coupes or convertibles due to some subtle design changes and a different grille and wheels.
These are the best British muscle cars in history. Some of them may still be on the road, so if you can get one, be sure to grab it fast. These cars will be harder to find as time goes on.
