The term 'facelift' is actually too much of a stretch for the 2011 M3 range that comprises of the Coupe, Sedan and Convertible, as there are far less changes than on the recently launched 2011 3-Series Coupe and Convertible models.
To sum up the upgrades, all three body styles of the M3 gain a new Auto Start Stop function that promises to reduce average fuel consumption and CO2 levels, while the Coupe and Convertible get modified LED tail lights and the Coupe and Sedan an optional Competition Package that sharpens handling.
