I came from a 2011 F25 35i SAP (loaded including DHP) with 19" staggered 309s on the run flat performance Continentals that were offered at the time. That X3 was amazing, especially since I had just got out of a 2001 LR D2. M-Sport was not available at the time so it was pretty much the performance leader in it's class at the time.

Compared to that, my current 2015 F25 35i M-Sport (loaded including DHP) is a huge upgrade in every aspect from interior finish to overall driving experience and performance. I am currently running with the 20" staggered 310Ms on Pirelli P-Zero run flats. I can say without a doubt that the ride is smoother, more composed, more nimble and more powerful than my previous 2011 F25 was... in any mode.

With that said, I thinks it's safe to say that the difference between (IMO and excluding looks of course) a 2014 pre-LCI and a 2015 LCI is marginal to slightly better to the latter simply because the line has been slowly evolving ever since 2011. The next big evolutionary change will be the release of the new G0x platform in 2017...which will be fun to compare to a 2011 F25.
