Auris hybrid: Proof a city Prius possible

A great Prius derivative for America?

The Toyota Auris has become a pretty successful car for Toyota in Europe, and that success is pushing Toyota to consider a hybrid version of the Auris, a subcompact, for the European market.

Why not rebrand the Auris hybrid as a city Toyota Prius for America? Why let Honda sell the cheapest hybrid cars in America?
