Changes by Model Year
In September 2008 sedan and Touring were updated. Compared to typically subtle BMW facelifts the change to the E90 and E91 were relatively extensive.
The front and rear bumper, the wing mirrors, the headlamps and the tail lamps which return to the classic BMW L-shape as well as bonnet (“hood”) and boot lid (“trunk”) were changed. The rear track on some models were increased by 24 mm (0.9 in). The BMW kidney grilles were re-arranged with a wider appearance. In the interior high-quality materials and trim are used, also some control elements were changed. The front seats were equipped with crash activated head restraints.
There were also technical changes to the optional navigation system “Professional”, that provided with an internal non-removable disk and high-speed keys (now supplied by Harman Becker instead of Siemens VDO). In addition to the new updated iDrive, internet access (special equipment) was also introduced.
Only the 330d engine was changed. It was changed to the new BMW N57 all-aluminium diesel engine with a variable geometry turbocharger, and will develop 245 PS (180 kW; 242 hp).
The E90 M3 only received the new rear design and iDrive system from the E90 2009 model year facelift.
