No matter which version of the 2015 BMW 3-Series sedan lineup you choose, you'll find good occupant protection as well as some handy active-safety features. And as for Sports Wagon and Gran Turismo models, don't expect any compromise in safety.
On all 2015 3-Series models, you get front and front side airbags, plus side head airbags covering both rows. Several other optional tech features might enhance safety.
Blind-spot monitors and lane-departure warning systems can be equipped for the first time this year. A camera-based forward collision warning system and front and rear parking sensors are available as part of a larger Park Distance Control package that adds a surround-view camera system for a bird's eye view in close parking spaces, or for pulling out of obstructed areas, such as an alley.
Automatic collision notification is standard on the 3-Series and can automatically call first responders if the car is involved in a crash.
The 3-Series earns mostly good marks from federal and independent testers. In federal testing, the 3-Series earned a five-star overall score, including four stars for frontal impact safety. The IIHS has returned mostly top "Good" scores, except in the small overlap front crash test, where it only earned a "Marginal" rating.
The federal government has extended those results for the sedan to both the wagon and GT, while the IIHS keeps their ratings valid for the sedan only.
