9. 2013 Jaguar XKR / XKR-S — 3968 pounds
Price: $98,375 / $132,875
Although a regular Jaguar XK coupe weighs only 3770 pounds, the faster XKR and XKR-S coupes tip the scales at 3968 pounds. Compared to the base XK, the performance versions add a supercharger to the 5.0-liter V-8 engine, boosting horsepower to 510 in the XKR coupe and 550 in the XKR-S. The cars also get performance equipment like stiffer suspension, larger brakes, and a rear wing, which adds even more mass to the British two-door, earning the XKR and XKR-S the number-nine spot on our list. Buyers who want a lighter — but also considerably slower — Jaguar coupe can opt for the base XK, which is powered by a non-supercharged 5.0-liter V-8 with 305 hp. It weighs only 3770 pounds.
