Don't, ever, make the error of building a plane optimised for short range.
When fuel was cheap and anything with capasity had to be able to fly coast to coast, standarizing on 1 type was a good idea.
That's why 737 and A320 fly 3000nm.
For almost all flights the 500 million Europeans make within Europe it is a total waste, a gross overkill.
ATR andBombardier will come with bigger props, as will India. Embraer said they will probably make their new 5 abreast optimized for shorter ranges too.
Times change.
