Vauxhall Insignia Scores Five Stars in NCAP Tests | Part Two

Vauxhall Insignia

Vauxhall Insignia

There is a plethora of standard safety equipment on all Vauxhall Insignias, including the following:

  • Anti-lock braking system with electronic brake force distribution, cornering brake control, comprehensive brake assistance system, that comprises emergency brake assistance, hydraulic brake-fade assistance, brake disk cleaning and hill start assistance.
  • Electronic Stability Programme (ESP)
  • Traction Control with engine and brake intervention
  • Three height-adjustable head restraints in the rear
  • Three-point safety belts all around
  • Belt-force limiters and pyrotechnic double belt tensioners in front
  • Seatbelt warning signals in front (on all rear seats)
  • ISOFIX child seat fixtures in the rear
  • Comprehensive airbag system, including multi-stage front and side airbags for driver and front passenger, head curtain airbags (front seats)
  • Adaptive brake lights that warn vehicles driving behind the car if it brakes suddenly or if ABS intervenes at speeds above 20mph. All three brake lights then flash at a frequency of five hertz and continue flashing for three seconds after the car comes to a stop
  • Pedal Release System
  • The latest generation active head restraints in front, which provide front occupants with highly effective protection against whiplash injuries
  • Super-strong passenger safety cell

The basis of passive safety in the Vauxhall Insignia is a rigid passenger cell mainly fabricated from high-strength steel. To absorb the impact energy in a crash, the front, side and rear of the passenger compartment are surrounded by crumple zones that deform and protect in a controlled manner.

At the front, three distinct loads paths are designed to absorb and channel impact forces: the front sub-frame, the longitudinal members carrying it and the upper rails leading into the lower A-pillars.

At the rear, two more longitudinal members are linked by the aluminium bumper beam. In the event of a heavy rear-end impact, these are designed to buckle and deform in a progressive manner, channeling crash energy towards the lower C-pillars, wheel arches and floor.

For side impact protection, where there is little scope to engineer a substantial crumple zone, the side body structure is designed to spread loadings. The doors have steel reinforcing beams that are mounted diagonally. This layout proves to be more effective in engaging the B-pillar, side sill and the floor and roof cross-members as a single network to bear the load bearing task.

Measures for pedestrian head impact protection included providing adequate clearance for all hard points under the bonnet, and also the adoption of a 'soft' bonnet design, with wide openings in the inner skin to provide flexibility as well as stiffness.
