Why do small cars make power so high?

I'm in the process of buying a new small car, most likely a Mazda3 Maxx or Hyundai i30 Elite, so I've been reading the specifications. I've tried at least five and all of them show maximum power at 6000rpm or above. That's all very well but, frankly, who drives at these sorts of revs on a daily basis? I've found that a lot of those new engines seem to be very weak under 2500rpm and, although it's good to know the maximum power, I think it would be useful to show the dyno graph, or at least being able to know how much power there is at about 3000rpm.
