Hei. My 320ia Gt xdrive gets about 0,95 L/km at this moment. That translates to about 24,8 mpg in city driving. My previous 2010 320dat got about 0,8L/km (30 mpg) in city driving.
Dont know if the 328i is suppose to use a lot more since its the same engine basically.
Tyres mean a lot and correct airpressure aswell
