And most people said the NSX was under powered for years, until one embarrassed them on a track (it was definitely under powered in the 2000's though).

It isn't about peak horsepower, it's about performance, and the 370Z was leading until the 2011 Mustang GT came out, and it is still pretty close, which the 350Z - 370Z update brought about.

I don't think a variable valve lift and timing throttle-less engine with a flat torque curve and 7500 RPM red line is out of date at all - add some direct injection and tuning, and it can beat the Mustang with just an engine and I/H/E mid-cycle facelift (though some more lightness would be nice).
