New development schedule
Infiniti JX was NNA’s first V3-P project which is a shortened development schedule, key reductions are:
Enhanced Digital phase activity by CAD data quality and CAE
Physical phase schedule 19.5 month (6.5 month compressed)

JX35 Torsion Targets
Rear Torsion requires a higher target to make up for reductions in other systems:
Tire width decrease for fuel economy improvement
Mass reduction

Several iterations of CAE were
run to fine tune stiffness and
increase mass reduction.
Critical parts for Body
stiffness are:
Red = Primary
Orange = Secondary

Design Challenges
Deep clearance pocket was required to eliminate
Styling bump at Hinge area. This reduced section caused
larger stress issues than expected in the digital phase

Safety – Roof Crush
w w w . a u t o s t e e l . o r g

The upper body construction minimizes the
intrusion into the occupant compartment
through the application of high strength
steels.
- Roof strength achievement with smaller section sizes to
meet visibility and roominess targets.

IMPACT SAFETY (Side Impact)
Designed to maintain integrity of the cabin in the event of a side collision by use of
Multi-Load Path impact force dispersion structure and use of high strength steel.
Side airbag
Energy absorption airbags with separate chambers for chest/abdomen and pelvis areas
allows for occupant injury reduction.
Inflatable Curtain
Occupants of all 3 rows are protected by the inflatable curtain airbags.
Safety Zone Body structure and efficient restraint systems allow for improved Safety
performance.
