2022 Acura MDX Body Structure

Body Structure

The 2022 MDX body structure is made with a significant concentration of higher-strength steels. The 1,500-megapascal “door rings,” are large single-piece structures encompassing the A- and B-pillars, hinge pillar, and front halves of the roof and frame rails.

Advanced High Strength Steel
To aid safety performance and long-term durability, the 2022 MDX uses three different grades of press-hardened and high-strength steel (HSS) in 60.9 percent of its body structure by weight, up from 54 percent in the outgoing MDX. This high-grade, high-tensile strength steel is applied to improve both dynamic and collision safety performance while mitigating weight. Altogether, 69.7 percent of the MDX body is composed of press-hardened steel, high-strength steel or aluminum — more than in any previous generation of MDX.
