I have a 2.8 a4 and i am looking to get the s4 biturbo. Will i get the same MPG on the s4 as i get on my a4 2.8?
I know that since i have 2 turbo i will prolly drive it harder but lets say they were being driven the same.

 

i dont know much about these cars or the engines in them, but it seems...since the s4 engine has 2 turbos, and you get one, it would of course depend of the size but you would most likely get the same gas mileage. injector size and other things come into play as well...

 

so if it was teh exact same enigine (which it sn't cyliners are .1L smaller) and injectors and all it would not directly affect the MPG?
