The way I see it america will never be able to make track cars, I've always wondered why the majority of american cars are automatic too?
Just like oweneades says - Because they're driving conditions are much more suited to automatics - very long distance cruising, or lots of in-town driving and heavy traffic
You have to remember that America is a much larger place, with longer journeys required from point to point.
America's able to make track cars - if they want to. Regardless of what we think, Corvettes et al have always ruled the autocross out there, even against European competitors - with tweaked C4s ('85 to '87 in particular - better than the C5s in autocrossing due to shorter wheelbase) commonly returning times faster than F430s, RX7 TTs and so on around tight, twisty, competitive circuits.
Don't forget the likes of period 60s Mustangs, Galaxies and so on that ruled the touring car series for years......Of course, not forgetting the GT40 as well....or the C5-Rs that have won their class in Lemans against various European exotica with 1-2 finishes several times.

The new ZR1 (which I'm sure you've read about, by now, seeing as it's come up umpteen times here) drives that point home somewhat after beating everything on the 'ring
Their needs, expectations and requirements differ, tis all - and consequently breed a different style and class of car
A lot of their stuff, also, is extremely capable when tuned and tweaked outside of the manufacturers specification. Gibbo's got a good example of that
