Utilizing extensive aluminum component, this innovative suspension design offers superior tracking stability and low unsprung weight. The five-link rear axle in lightweight steel, ensures precise wheel guidance as well as excellent roll comfort, ensures class-leading agility and dynamic handling.
Safety features include the first front-to-rear Head Protection System to be offered in the 3 Series employs a curtain-type system, which takes up less space in the headliner and can remain inflated for several seconds after deployment, especially important in case of rollover. The 3 Series is BMW's first to employ seat-mounted side-impact airbags, as opposed to the door-mounted type of the predecessor and other current Series. In their function of protecting occupants' pelvis and thorax regions in side impacts, the seat-mounted airbags are equal to the door-mounted type, but offer greater freedom for the interior designers to achieve their functional and esthetic goals. It has a sophisticated electronic control strategy for managing the deployment of airbags and safety belt tensioners.
This approach to optimal effectiveness of safety systems now becomes more precise, thanks to a new sensing mat in the front passenger seat. Called OC3, the mat is more highly sophisticated than its predecessor; it measures the weight and analyzes the pressure distribution of the occupant in order to distinguish between an adult and an infant in a child safety seat.
