A point here is that DI and turbocharging has made the old adage that the gasser needs to rev like crazy to produce power no longer holds true. The 3.0 Audi gas example that was given has an extremely flat torque curve, one any diesel would be proud of. It produces that 364 lb ft from 1370 RPM all the way to 4500 RPM.
BTW that 3.0 diesel in European S trim is now putting out 340 HP and 516 lb ft but we know it won't meet NA emission standards. Wish it did cause it must be a hoot.
