ACE Body Structure Design
The MDX uses the next-generation Advanced Compatibility Engineering™ (ACE™) body structure to enhance occupant protection and crash compatibility in frontal crashes. This structure helped the MDX (FWD and SH-AWD® models, Sport Hybrid model have not been tested) achieve Five-Star Overall Safety Ratings from the NHTSA in single-impact tests.
- The 2018 MDX was also rated as a Top Safety Pick by the Insurance Institute for Highway Safety (IIHS)
- The ACE™ design utilizes a network of connected structural elements to distribute crash energy more evenly throughout the front of the vehicle.
- This generation of ACE incorporates extra braces at the front corners to absorb and distribute impact energy from narrow off-set collisions, in which a small portion at one side of the front end must absorb the collision forces.
- The outer braces are designed to transfer impact load toward the center of the frame where the energy can be distributed around the cabin area more evenly.
- This enhanced frontal 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.
