Major changes included:
The 2013 model year ushered in an all-new base model for the 3 Series in the form of the 320i. The new 320i was only available in a sedan format, and included the 3 Series new design language that BMW released the year prior. Under its hood, the 320i carried a 2-liter four-cylinder that produced 180 horsepower and 200 pound-feet of torque. A six-speed manual transmission was standard. xDrive all-wheel drive and an eight-speed automatic were optional on the 320i.
