The second-generation BMW 4 Series received a 5-star rating in the Euro NCAP crash test. NCAP only conducted additional tests where the cars’ performance may differ, given that it is structurally similar to the 3 Series. This crash test video for the BMW 4 Series Coupé G22 gives an idea of the safety systems’ effectiveness:
Several 4 Series Coupe and Convertible underwent through a test, because the side-impact tests use a fundamentally different crash structure than the front impact tests. During the frontal offset test, the BMW 4 Series Coupe and Convertible passenger compartment remained stable.
In both the side barrier test and the more severe side pole impacts, the BMW 4 Series received maximum points. This indicates a well-protected critical body. In the event of a rear-end collision, the front seats and head restraints’ test revealed good protection against whiplash injuries.
The coupe scored 97% for adult occupant protection, while the convertible scored slightly lower at 96%. The same tendency can be seen protecting smaller passengers and children. The Coupe’s safety rating is 83%, while the convertible’s rating is 80%.
In tests of its functionality at low, city-driving speeds, the standard-fit AEB System received the highest marks. With no collisions occurring in any of the scenarios. The convertible receives 15.6/16 points for side impact protection, while the coupe receives 16 out of 16 points.
