One word for this "This car is made here, boo hoo!"

Globalization.

Also, 400HP 4-cylinders will not run as long as 400HP v8s with similar parts for obvious reasons (more stress being the most obvious, there is no replacement for displacement in the end. Put the same type of part on each engine and the larger engine will make more power.) They also won't run for 200k miles, unless they're something supercarish, and even then probably not.

Oh, and your junk heap isn't more advanced than shit...its just built for performance, DUH!
