Compression ratio is different (10:1 for 28i & 11:1 for 20i) for F10 & F30, but same for both models of x1.
What maybe happening is BMW is doing some sort of binning with these engines (i.e. if output is above official figures then it'll be a 28i, otherwise it'll be a 20i), after that they'll lock the power down for the 20i.
For me I'll not bother with the 320i as there's vitually no price difference between the 2 if u spec them the same, plus it comes with smaller brakes than the 328i.

Dont compare the F30 320i engine with the X1 or F10 .20i engines, they are not the same
