13. Corvette Conan ZR-12
The C4 chassis was a state-of-the-art component when they introduced it in the mid-80s. All during the production, Chevrolet knew it could handle much more power than stock. So, to test exactly how much power the C4 chassis could withstand, the Corvette team built the Conan ZR-12 prototype.
This custom Corvette had a frame that was five inches longer than stock as well as an enormous V12 engine under the hood. The engine delivered 700 HP and an insane 750 lb-ft of torque. And even with that kind of power under the hood, the C4 chassis proved to be a perfect match.
