I have to say the JC kinda has a point. But our market is different, as it's been said before, the US has a lot more long smooth roads, hence handling has never been a real issue.
Smaller, high reving engines are great in Europe, if you know how to work the gear box, you can get a lot of performance out of them. In the US, cars were generaly much larger and thus heavier, so big torquie engines were the natural choice. When kids started racing they used what roads and engines they had on hand. Long, straight roads, big V8s...drag racing was born. NASCAR was started by moonshiners smuggling illegal booze from one county to another on back roads using those same heavy cars, and one day they got organized and started racing on the beach of all places!! Again, cornering capabilities were not important.
Road racing does have it's place here, but it doesn't have the tradition that drag racing and NASCAR have, so our performance cars have always reflected those traditions. Look at the import (mainly Asian) racing scene here, they drag race for the most part. Impressive to see 4 cylinder FWD Honda Civics run 10.5 second 1/4 miles.
European cars reflect the roads, drivers and types of racing and motoring traditions you have on hand. In other words, it's all good.
