2012 Ford Focus ST BODY AND CHASSIS Structure - European Specs

StructureComputer-optimized, high-efficiency, unitary-welded steel
Safety Elements - Body Ford Intelligent Protection System (IPS) with optimised bodystructure to achieve moderate deceleration levels whilst minimisingintrusions into the passenger compartment in offset and straight frontimpacts, side impacts and rear impacts:

  • Front bumper system, consisting of boron (Ultra High Strength Steel) bumper beam and HSS (high strength steel) crash cans,bolted to the front side rails (to minimise repair cost in a lowspeed impact, also considering slightly angled impacts), optimized for maximum energy absorption in low and high speedcrash events, with controlled deformation in bumper facia in frontof the beam to minimise effect of an impact to pedestrians
  • Rear bumper system, consisting of a boron steel bumper beamwith welded HSS crash cans, optimised for maximum energyabsorption in low speed impact to minimise repair cost, alsoconsidering slightly angled impact directions
  • Front and rear energy-absorbing crumple zones through welldefined deformation patterns of the main structural elementssuch as bumper systems; front and rear laser welded siderailswith optimised panel gauges; optimised front subframe withcontrolled deformation pattern serving as additional load pathand energy absorbing unit
  • Stiff occupant protection cell through utilisation of HSS andUHSS materials (boron steel) in the A and B pillar, roof and sillarchitecture, supported by lateral structural elements in floor androof, also delivering excellent side impact and side pole impactprotection, cross beam and steering column support to enablewell controlled steering column kinematics and ride down duringthe interaction with a forward moving front occupant in a highspeed frontal crash
Passive safety and restraint system elementsFord Intelligent Protection System (IPS) featuring:

  • Full size driver (~60L tethered volume) and 110L passenger airbags featuring latest single stage inflator technology
  • High power pyrotechnic belt pretensioners (retractor
  • pretensioner) and belt load limiting for front-seat safety belts
  • Standard inflatable side curtains for front, and second row seat occupants
  • Standard thorax-protecting side airbags for front occupants Horizontal stroking steering column for optimized energy absorption and leg protection
  • Safety Pedals
  • Passive neck injury protection system on front seats
  • Three-point safety belts in all positions
  • Safety belt reminders for driver and front passenger
  • ISOFIX child seat attachment anchors on outboard seats second row
  • Approval for universal ISOFIX child seats
  • Optional passenger airbag deactivation kit (dealer fit).
  • Optimisation for wide range of human body profiles, from 5 percent female to 95 percent male
  • Crash severity sensing system with satellite sensors in B-pillars and front-end module
Bumper systemDamage-resistant, full-depth moulded reinforced polypropylene
Security system elements
  • Perimeter alarm with interior volume sensing (optional)
  • Advanced Ford PATS immobiliser
  • Key fob and manual-key operated central locking (FordKeyFree-System available as option)
  • Global closing feature for power windows
Corrosion protection24-stage paint and body protection process, including zincprecoating for all relevant exterior panels, optimised dip phosphatecoat, electrocoat primer, primer/surfacer and basecoat/clearcoatsystem, plus comprehensive cavity wax injection, PVC underbodycoating and stone chip protection. Thick PVC sealing beads forflanges. Front plastic wheel arch liners, rear textile wheel arch liners,anti scuff strips on inner doorsills.
Suspension Front – Macpherson strut suspension with isolated subframe andelectric variable ratio steering. Shocks, springs, anti-roll bars andspring aids adopted to ST requirements

Rear – Control blade rear suspension derived from Focus RS. Shocks,springs, anti-roll bars and spring aids adopted to ST requirements

SteeringType – Rack and pinion steering with rack-mounted Electric PowerAssisted Steering (EPAS)
