Next Generation Advanced Compatibility Engineering (ACE)
Next Generation ACE Body Structure
The HR-V utilises the next generation version of Honda’s proprietary Advanced Compatibility Engineering (ACE) body structure to enhance occupant protection and crash
compatibility in frontal collisions. ACE utilises a network of connected structural elements with extensive use of high tensile steel to distribute and disperse crash energy more evenly throughout the front of the vehicle.
The front crash energy management helps to reduce the forces transferred to the passenger compartment and can help to more evenly disperse the forces transferred to other vehicles in a crash. It is designed to help the HR-V achieve top class crash test ratings. The ACE body structure also helps mitigate the potential for under ride or over ride situations that can happen during head-on or offset frontal impacts between vehicles of varying size and ride height.
Unlike most conventional designs where the direct frontal crash energy is transferred to the lower load-bearing front body structure, ACE actively channels frontal crash energy to both upper and lower structural elements. The collision force is dispersed through the floor chassis rails, side sills and A-pillars. By creating specifically engineered pathways that help distribute these frontal impact forces through a greater percentage of the vehicle’s total structure, ACE can more effectively direct those forces around and away from the passenger compartment to help limit cabin deformation and further improve occupant protection.
The HR-V’s body is constructed with high tensile steel and hot stamped steel reinforcements and stiffeners. The result is low weight with high rigidity. This directly contributes to accurate steering, precise handling, excellent ride quality, low NVH and high durability.
Many areas of the platform have received special attention to make them even more rigid. These include the front sub frame and lower dash cross member, the rear damper mounting structure, and the rear hatch opening. This high front and rear contact point rigidity helps improve handling by reducing suspension geometry changes. Specifically improving rear body performance is a new gusted girdle shaped shock mounting frame and underbody bracing in the form of a V shaped performance rod.
Construction High Efficiency Frame Joins
In addition to the use of ultra high strength steel to improve rigidity, the HR-V uses high efficiency frame joints in several key areas of the body structure, including at the top and bottom of the A, B and C-pillars. These frame joints also require fewer reinforcing parts, resulting in both a stiffer and lighter structure.
Pedestrian Injury Mitigation Design
The HR-V has an impact absorbing front body design to help dissipate energy in the event of a frontal collision with a pedestrian. Research by Honda shows that the features can dramatically improve a pedestrian’s chance of survival if struck by a moving vehicle.
