5. Ford Thunderbird Turbo Coupe
Ford Thunderbird isn’t the car you would normally consider a muscle car but in the `80s, Ford introduced a couple of Thunderbirds that could have that designation and were an interesting addition to the performance car scene in those days. Although the T-bird was available with a V8 engine, the best performing version was, in fact, the Turbo Coupe, introduced in 1987.
The TC received a Mustang SVO, a 2.3-liter turbocharged four-cylinder engine with a manual transmission, 190 HP power level and top speed of whopping 143 mph. The top speed was affected by the relative lightness of the car and aerodynamic shape of the ninth generation Thunderbird.
