Since the 3-Series, in sedan form, is an all-new model for 2012, it hasn't yet been rated by either of the major U.S. crash-test agencies. However, Coupe and Convertible versions carry over in their previous E90 forms for one more year, and earn a “good” score for frontal impact and a “marginal” score for side impact from the Insurance Institute for Highway Safety (IIHS).
The 3-Series sedans have a completely new structure with more aluminum than ever before, along with ultra-high tensile steels, to help make it light yet protective.
Active safety features are available this year and include options such as blind-spot monitors, lane-departure warning, and forward collision warning. The 3-Series also includes an emergency services notification system that alerts first responders in a severe crash.
A rearview camera is bundled in a parking assistance package that includes a surround-view camera system that stitches together many camera angles to provide a bird's-eye view of the car when parking in tight spaces.
All 2012 3-Series models include front and front side airbags, plus side head airbags covering both rows.
