The Alfa Romeo Giulietta and the BMW 5-Series have been awarded a five-star rating in Euro NCAP testing.
The BMW features highly resilient bearer structures, precisely defined deformation zones, numerous airbags (front, pelvis-thorax, and side curtain), active front headrests, and an active bonnet (which uses pyrotechnic charges to raise the hood to reduce injury to pedestrians and cyclists). More importantly, the 5-Series is equipped with an advanced passenger cell which causes forces from a front-end collision to be "dissipated via a number of different load paths in the floor assembly, side frame, front wall and roof."
Likewise, the Alfa Romeo Giulietta was "designed and built to obtain maximum passive and active safety performance." It boasts a Vehicle Dynamic Control system, assisted panic braking, six standard airbags, and Self Aligning Head Restraints (SAHR).
