Strategy for Unibody vs. Frame
Key Benefits of Improvement
 Ride & Handling
 NVH
 Body Stiffness
 Mass Reduction
 Fuel Economy

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
JX35 Competitor #3
www.autosteel.org
JX35 Torsion Targets
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

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.
