The 2009 3-series comes in a variety of flavors: the naturally aspirated 328i, the twin-turbo 335i, and the new twin-turbo diesel 335d. The 328i and 335i can also be had with BMW's xDrive all-wheel-drive system. Only the sedan and wagon versions are getting the updates shown here; the coupe and convertible versions remain the same.

BMW expects the diesel version to offer the same level of performance as the gasoline versions. With the twin-turbo diesel, which will be sold in all 50 states, the car gets 265 horsepower and an astounding 425 pound-feet of torque. BMW claims 6 seconds from 0 to 60 miles per hour.

The most apparent change with the new 3-series will be the new iDrive controller and menu. We saw an example of the new iDrive screen in the 7-series preview. This new iDrive controller includes hard buttons for quick access to the sound system, telephone, and navigation.
