Across the entire 2014 BMW 3-Series lineup you get some innovative occupant protection and useful active-safety features. And based on the information available at this point, Sports Wagon and Gran Turismo models should be just as safe of a bet as sedans.
In Insurance Institute for Highway Safety (IIHS) testing, the 2014 BMW 3-Series earns top 'good results in all subcategories except small overlap frontal impact--where it performed only to 'marginal' standards. In federal testing, the 3-Series earns five stars overall, including four stars for frontal impact and five stars for side impact.
It's worth noting that the federal government has extended those results for the sedan to both the wagon and GT, while the IIHS hasn't yet done so.
All 3-Series sedans include front and front side airbags, plus side head airbags covering both rows. Several other optional tech features might enhance safety. Active Blind Spot Detection and the Lane Departure Warning System include a camera-based Collision Warning system and are for the first time offered in the 3-Series. It's offered as part of an enhanced Park Distance Control is a new rearview camera system with side view and top view modes to give a bird’s-eye view in close spaces and to monitor cross traffic when pulling out of concealed exits (like alleys).
The 3-Series also includes an Automatic Collision Notification system that relays to emergency responders detailed information on the type of accident and likely level of trauma.
