American cars often differed from their overseas 4-wheel counterparts. They were usually much larger which is a feat that mandated additional power. Things are still, more or less the same, but this strategy has had many ups and downs over the years. American muscle car reached its peak in late sixties and 1970 model year. Next decade and a half would be a roller coaster. A roller coaster towards the bottom. Malaise era hit the car world so hard that the industry would need more than thirty years to heal its wounds as first serial production non-supercars with at least 400 horsepower on tap only arrived after the millennium.
Needless to say, most powerful American production cars in history all hail from twenty tens. Not only has technology advanced to a certain level that allows 600+ horsepower cars, but the climate has been favorable as well. Of course, we’re only talking about factory production cars here. Callaway, Hennessey, Roush and co. will have to find another place to promote their majestically tuned beasts. Anyway, here are the top 10 most powerful domestic production cars ever made.
2013-2014 Ford Mustang Shelby GT500 (662 hp)
Shelby Mustang has been absent since 2014 and it’s already being missed. Sure, GT350 is a superb car, but that GT500 moniker simply doesn’t go hand in hand with the retirement in my opinion. I can name plethora of reasons to defend that statement. Last GT500 itself could name you at least 662 reasons. Incidentally, that’s exactly how many horsepower that muscle car has had. Unlike the current GT350 models which rely on normal aspiration, GT500 from a few years ago found its spark in 5.8L supercharged V8 mill. But we won’t hold that against it. After all, it’s the most powerful factory-built Mustang ever produced. Question is, for how long?
