No, you're actually wrong. Yes, torque and HP are equal at 5252 RPM. Since all your Japanese car (VTEC comes to mind) make peak HP much above that, what does that tell you? You torque has well fallen off by then. And yes, torque is more important. Torque all comes down to the amount of turning force at the crankshaft, which, if I remember correctly, is what engines use to make HP, right? The physics of engines are too complex for you to argue except that it all comes down to this: with greater displacement, the engine doesn't need to work as hard to turn the crank, for the engine is compressing mor air/gas mixture per stroke (or 4 strokes, rather). And don't come back with that "HP/Liter" again - since it takes 4 times the energy to make twice the power. Oh, and American cars invented VTEC 50 years ago, except we use it to make power throughout the entire RPM band (off-idle to redline). Too little, too late.
