I think ppl (maybe) used to their previous NA bimmers or other vehicles meeting or beating epa numbers and from my limited experience with an X1 28i xdrive- I couldn't get close to sniffing 30 let alone 33. EPA figures on the AWD 28i are wrong IMO by ~15% and many people are/were attracted to the having your cake and eating it picture that the numbers paint and they're rightfully pissed cause it ain't happening. Many may be thinking they should have just dropped the extra for the 35i- or maybe something a bit more practical/cost effective or diesel
