21. Shelby GT 350 R
Even though Ford based the Shelby on the Mustang GT, much of the suspension, design, aero package and engine were new. The most significant single difference was the fantastic Voodoo engine, which has a 5.2-liter displacement, 526 HP, and 429 lb.-ft of torque. The main feature of this high-revving powerplant is the flat-plane crank technology (via Car and Driver).
Ford’s investment in the Shelby GT350R paid off and the performance is mind-boggling with 3.9-seconds 0 to 60 times. But the numbers don’t do this car justice. The Shelby GT350R is a pure sports car that delivers fantastic driving dynamics as well as an unforgettable driving experience.
