ACE Body Structure and Related Safety Construction
Body construction now includes Honda's Advanced Compatibility Engineering™ (ACE)™ Body Structure that enhances frontal collision energy management through a network of load bearing structures in the front of the vehicle. This newly developed front-end frame structure (similar to the all-new 2005 Honda Odyssey ACE Body Structure) incorporates new upper and lower frame members to significantly enhance energy dispersion in a frontal collision throughout the upper and lower load bearing channels in the body. The ACE concept differs from traditional crash designs that guide a high percentage of collision force through a vehicle's two lower channels in a collision. The ACE design with its polygonal front structure helps reduce the potential for misalignment with the frame of the opposing vehicle. Taken together, these features are designed to increase compatibility between vehicles of different size categories for enhanced occupant protection in the event of a collision.
The Civic's ACE body structure is configured for high energy absorption. In the event of a frontal collision, the body structure with its front-mounted polygonal main frame is designed to prevent structural penetration while distributing forces evenly through multiple major load bearing pathways - and away from the passenger compartment. For comparison, a conventional body structure generally concentrates the loads from a collision through two pathways running longitudinally through the lower portion of the frame. In the ACE body structure for example, frontal impact force can be distributed from the front of the vehicle through the side sill, floor frame and A-pillar in order to reduce the cabin deformation.
The bottom line is that the ACE body structure enhances energy distribution during a collision because impact forces can be distributed through more vehicle mass and away from the passenger compartment.
For side impacts, all models now incorporate high-grade, high-strength steel body side frame structure. Additionally, coupe models apply special gussets used to further help direct forces throughout the frame for side impacts.
