For 2 cars I personally can compare.
2011 Hyundai Elantra, Rated at 29 city, 41 hwy (at least when I bought the car in 2011) in reality? City 23-24, hwy 33-34.
2013 VW GTI rated at 24 city, 31 hwy, in reality? 25 city solid, and 33-34 hwy solid.
So it all depends on the manufacturer I reckon. From what I have gathered from reading the rags, and people I know, most Turbo 4's make about the same MPG's as any modern V6. Did you read the Article in the new Automobile Mag I believe it was about the new 2015 Camry? The Toyota Rep stated "we stuck with our V6 vs a turbo 4 like our competitors because or V6 beat the turbos in every single category".
Only benefit I personally like about a turbo is the flat torque curve. Its nice to be in any gear and hit the gas and your gone, vs naturally aspirated you have to get some revs up, unless you have a V8.
One example, though its a 4 cyl comparo, my friends 2012 Hyundai Sonata with the 2.4 GDI motor, going up the same 6% grade to the local big city and it downshifts all the time to maintain speed. Vs. My Turbo 4 making the same HP rating can pull the same exact hill in 6th and never downshift.
Just love a turbo motor, just dont buy one thinking you going to get better gas mileage. Well maybe you can if you drive with an egg under your foot.

So I guess yo9u would have to keep it out of turbo boost mode to get decent mileage? Geez, you go up a 6% grade in top gear? What RPM, how much turbo boost to do that?
