Updates include new front and rear bumpers, restyled front headlights and restyled taillights with LED technology. A refreshed interior is also presented featuring the new shifter from the new X5, and the addition of the new BMW Drive-By-Wire system. The 2008 model of the 520i has gotten a new engine: a 2.0 liters 4 cylinders instead of the R6 2.2 liters.

BMW is considering bringing its diesel powered models to the United States in late 2008.
