Thats not correct.
If you are referring to the sedan yes 2010 amd 2011 are LCI models
If you are referring to e92 coupe then there is a big difference between 2010 and 2011. Engine wise 2011 is a n55 vs a n54. Also 2010 is a pre lci while 2011 is lci models
You can always google lci vs pre lci and n55 vs n54
