In truth, the 662-horsepower rating of the GT500 doesn't tell the whole story. The big supercharger riding on the top of it takes about 150 horsepower to compress the 14 psi of air into the 5.8-liter V-8. That puts the total output of the GT500's engine, at the crank, at something north of 800 horsepower.
While "only" 662 of those ponies are accessible for forward thrust, it's still an amazing combination of power, speed, handling, and price.
