16. Shelby Cobra 427
With a 0 to 60 mph acceleration time of 4.3 seconds, Shelby Cobra 427 was the fastest production car in America in the sixties. Putting the biggest Ford V8 engine in the lightest roadster body was as equally extreme then as it is today. But there’s one thing you must know.
The Shelby Cobra 427 has a 7.0-liter V8 with around 400 HP. They put it in a tiny roadster body that only weighs about 2,000 pounds. So, with around 400 HP sent to rear wheels in a body that is so light, the Cobra 427 spelled trouble from the moment they introduced it.
