Information is a bit loose but in these photos we can see a slightly new body kit, new 18 inch wheels and special red leather interior with navigation.  Look for a new engine possibly the 265hp 2.5 liter flat 4 cylinder turbo as the air scoop in the hood suggests instead of the current normally-aspirated flat six cylinder engine with 245hp.  The Bilstein sport suspension will remain.
