It says 28 mpg, but you've got to consider some things.
First, those are the city economy numbers, which are always lower, so you should compare to the 31 mpg (37 mpg UK)of the combined number.
Second, the engine in those US Fiestas are the last-gen 1.6 16V so it is a cheaper and older engine,they've done so because those cars in the US are the cheapest ones in the market, in Europe the 1.0 Ecoboost is quite expensive.
Third, the testing system is different, often the cars in the US really get what the manufactures claim, otherwise they are prosecuted by false marketing (Kia and Hyundai had to pay millions recently because of that). In Europe the tests achieve huge numbers, that can't be reproduced in normal driving.
