Full inner frame structure is adopted for further enhancement of rigidity and strength.
The upper framework joint forms a load path to the platform, improving torisional rigidity, while the cyclical framework around the rear gate strengthens cargo space opening rigidty. The improved joint in the front bulk joins the platform and upper framework securely.
Urethane foam: applied at cross member, and improved eigenfrequency
This highly rigid and lightweight material has been injected into the cross-section of the floor cross member to suppress floor surface vibrations.
Improved load transfer efficiency by removing parting portions from corner area.
Reinforcement with thermoset resin: effective area are chosen to suppress deformation at the opening area.
