You just can't beat displacement in those two areas.

 Not necessarily a problem with small capacity, although I agree that it often is a problem. To get good torque off idle from a small engine, you need a big turbocharger, probably with variable geometry, to get lots of air in at low engine speed. 
 
And you also have to build the engine solidly enough and with a big enough flywheel to stand up to the power pulses. In fact this is probably why there is usually a lack of torque off idle on small engines - the smaller capacity does not need as big a flywheel to idle smoothly so it doesn't get it!
