Ford loves to remind us that the 2020 Mustang Shelby GT500 is the most powerful street-legal car in the company's history. Under the hood is a 5.2-liter supercharged V8 that produces a Hellcat-crushing 760 horsepower and 625 lb-ft of torque.

This enables the potent pony car to hit 0-62 mph in around 3.5 seconds, do the quarter-mile in less than 11 seconds, and hit a limited top speed of 180 mph. Ford also recently confirmed the 2020 GT500 will do 0-100-0 mph in just 10.6 seconds. It already delivers supercar performance, but Hennessey has wasted no time taking it to the next level.
