20 Shelby GT500

It’s hard to believe that Ford will ever make a more ultimate Mustang than the 2021 Shelby GT500. Of course, somebody probably said the same thing when the 1968 Shelby GT500 KR came out, and look where we are now. Still, the GT500 is just about the fastest thing on the road for under $100,000. Ford fits it with a monstrous 760-horsepower 5.2-liter supercharged V8, massive brakes, massive tires, special aerodynamic body pieces, and an adaptive suspension that allows you to both dominate a racetrack and comfortably cruise on the highway.

The GT500 has such a breadth of capabilities that it’s hard to compare it to one specific class. On the bonkers-horsepower muscle car front, there’s the Dodge Challenger Hellcat Redeye. It has 797 hp and superior comfort, but it comes at the expense of precise and sporty handling.
