I've driven a friend's S2000, and the powerband is unmistakeable. You get it above 6000rpm and the engine gives you a swift kick in the rear. Same thing on a Toyota Celica GT-S albeit with a much lower red-line, so the powerband is much more constrained. I test-drove an RX8 and it was much less clear how to get any power out of the thing. It makes much sound and fury as you rev it up, but it doesn't really feel any different than it does at lower RPMs. I nearly gave the poor dealer a heart attack while I was trying to push that damn car. "Was that sound the over-rev indicator?"
