side frame, in the bulkhead and in the roof, subsequently being absorbed by
the deformation zones and thus kept far away from the passenger cell. The
load-bearing structures essential for this transmission of forces are made largely
of multi-phase and heat-moulded steel.
Within the interior not only frontal and hip/thorax airbags play an essential role,
but also curtain airbags both front and rear, all naturally coming as standard.
Depending on the type of collision and its severity, integrated safety electronics
mastermind the restraining effect and the time at which the airbags are
activated. Among other things, this means that airbags not required are not
activated in the first place, but are nevertheless still available for a possible
secondary, follow-on collision.
The frontal airbags come with a two-stage gas generator and may be activated
with varying intensity, depending on the severity of an accident.
All seats come with three-point inertia-reel seat belts. The restraint systems
furthermore feature belt force limiters with an additional belt latch tensioning
function on the front seats.
To prevent cervical spine injury in the event of a rear-end collision, the front
seats are equipped as standard with crash-activated headrests. Masterminded
by the car’s safety electronics, this sophisticated system ensures that in
the event of a collision the front end of the headrests move forward up to
60
millimetres or almost 2.4" and upward by up to 40 millimetres or nearly 1.6",
reducing the distance between the occupant’s head and the headrest before
the occupant is pushed back by the forces acting on the vehicle.
The headrest thus provides an even greater stabilising and safety-enhancing
function, reducing the risk of injury or over-stretching of the occupant’s cervical
spine.
Yet a further point is that the rear seats come as standard with ISOFIX child seat
fastenings. All restraint systems are masterminded by central safety electronics
and the safety steering column of the BMW 5 Series Gran Turismo comes with
a load-dependent deformation unit as well as an extra-large thrust element
protecting the driver additionally from collision forces coming from the engine
compartment. And, last but certainly not least, to optimise passive pedestrian
safety both the engine compartment lid and the side walls give in appropriately
in the event of a collision.
