Digital Activity
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
JX35 Competitor #3
Rear Torsion requires a higher target to make up for reductions in other systems:
Tire width decrease for fuel economy improvement
Mass reduction

JX35 Torsion Targets
Orange = Secondary
Red = Primary
Several iterations of CAE were
run to fine tune stiffness and
increase mass reduction.

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

IMPACT SAFETY (Roof Crush)
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.

<The Merit to Users> Safety Zone Body structure and efficient restraint systems allow for improved Safety
performance.
IMPACT SAFETY (Side Impact)
<Key points for side impact>
<Body Structure> 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.
<Restraints> 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.
