SAFET Y   Protective
Roll Stability  Control  (RSC)
Frontal  structure
In the event  of an emergency  manuever,  Volvo’s Roll Stability  Control  (RSC) can  step in
to help prevent  the vehicle  from rolling  over. It features  a gyroscopic  sensor  that
registers  the vehicle’s  lean angle  and rollover  risk. If required,  RSC  will cut engine
power or  brake one or more  of the wheels  just enough  to reduce  the centrifugal  force
and help  regain balance.
The generous  front deformation  zones  are designed  to yield  in a controlled  way to help
absorb  crash energy  before it reaches  the cabin.  The transversely  mounted  and very
compact  engine enables  optimal  use of the deformation  zones  to help protect
occupants.  Longitudinal  steel  struts help  disperse crash  energy away from  the front to
the rear of the vehicle,  further helping  to reduce the strain on  the occupants.
SAFET Y   Protective
Restraint  technologies
In a collision,  Volvo’s  restraint technologies   interact  to help reduce  the impact.  The
safety  belts with pre-tensioners   activate  within a few  thousandths  of a second in
the event  of a collision  or roll-over  and tighten  the belt to help  keep the occupants
securely  restrained.  The front seat  safety belts  then release  a little  so that the driver
and passenger  are cushioned  by the  airbags in  a controlled  manner. Helping  to
optimise  protection,  the dual-stage  airbags  adapt the level  of inflation  depending  on
the force  of the collision.  The driver’s  airbag  also interacts  with the  deformation  of the
collapsible  steering  column.  Side airbags  in the front seats  help reduce  the risk of
serious  injuries in  a side collision.  In a collision  or roll-over,  the Inflatable  Curtain
(IC) helps  protect the  heads of both  front and rear  outboard  occupants.  It also stays
inflated  for some seconds  to provide  prolonged  protection  for subsequent  impacts.
Lower cross  member
Whiplash  Protection  System (WHIPS)
To help protect  the occupants  in an
oncoming  car with lower  positioned
bumpers,  there’s a low  cross member
integrated  in the front  structure.  In an
impact,  this cross  member is designed  to
help activate  the other  car’s own
crumple  zones and other  safety systems
to help reduce  the risk  of injury.
Integrated  in the front  seats, Volvo’s  WHIPS cradles  the occupant  to help  reduce the
risk of whiplash  injury  (one of the most  common types  of traffic  injury  and often the
result of  a low-speed  rear impact  collision).  The function  is activated  by a collision  of
sufficient  force from  behind. Independent  research  has shown  that WHIPS  is one
of the most  effective  systems in the  world and can  reduce the  risk of long-term
invalidity  by 50%.
