16. Shelby Cobra 427
With a 0-60 mph time of just 4.3 seconds, the Shelby Cobra 427 was the fastest production car in America in the ’60s. They put the biggest Ford V8 engine in the lightest roadster body, so it is 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. This is too much for a tiny roadster body that only weighs around 2,000 pounds.
With all that power going to the rear wheels in a body so light, the Cobra 427 spelled trouble form the moment they released this speed demon. There are numerous reports of fatal accidents and owners crashing their cars as soon as they got them. Remember, this car doesn’t have any stability control or electronic aids. Putting 400 horses behind those four tires makes it one of the deadliest cars Detroit ever produced.
