New Model Body Technology
BODY CONSTRUCTION AND HIGH STRENGTH STEEL CONTENT
• Steel parts are color-coded based on their tensile strength in megapascals (MPa).
• High strength steel is defined as any steel with a tensile strength of 340 MPa or higher.
• Steel repair and welding procedures vary depending on the tensile strength of the parts involved.
• Refer to the body repair manual for complete information.
1,500 MPa (HOT STAMP) STEEL LOCATIONS
The one-piece front door outer stiffener rings and door
reinforcement beams are made from 1,500 MPa steel.
This steel is stronger than ordinary steel, so it can help
protect vehicle occupants while reducing overall vehicle
weight to improve fuel economy.

3-BONE PLATFORM STRUCTURE
A new “3-Bone” platform structure is used on this vehicle.
• The structure improves impact load management around
the cabin while reducing weight.
• Additional floor reinforcements may require replacement
or spot weld removal if damaged in a collision.
• Limited sectioning allowed to the Front side frame and
Rear frame B parts. Refer to the body repair manual for
complete information.
STRUCTURAL FOAM LOCATIONS AND REPAIR
Structural foam bulkheads are used to improve body
stiffness at the left and right inner panel assembly (A)
and inside the floor rear crossmember assembly (B).
Replacement part assemblies have the structural
foam pre-installed.
• A structural foam joint is used on a bracket that connects
the left and right side center frames under the front floor (C).
When replacing either the left or right front side frame
assemblies, a special room-temperature cured 2-part epoxy
structural adhesive (L&L Products L-0504 or equivalent)
is required to replicate this joint.
• Because of limited shelf life, the adhesive must be ordered
at the same time as the replacement front side frame.
• Once the adhesive/foam is applied, the parts can be
assembled and welded. The repair adhesive material
will cure at room temperature in 24 hours.
