범퍼빔에 무슨 짓을 한걸까요? 무슨 짓을 했길래 범퍼빔만 바꿨는데 Marginal에서 Acceptable로 등급이 올라갔을까요? 위 두번째링크와 아래 iihs.org링크에 어느정도는 설명되어 있네요.

위 링크의 설명
The Honda Fit was redesigned for the 2015 model year. (The 2014 model year was skipped except for a limited number of plug-in battery-electric variants.) Two small overlap front tests of the Fit were conducted. In the first test, the bumper beam, a steel bar located behind the plastic bumper cover, broke free of the frame rail on the passenger side of the car early in the crash. This caused much more of the crash energy to be absorbed by the driver side than Honda intended, resulting in extensive intrusion into the driver survival space and excessive upward movement of the steering column.
As a result, Honda improved the strength of the bumper beam welds for all Fits built after June 2014 and has announced a "product update" to replace the beams free of charge on cars built before the change was made on the assembly line (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door). In the second test of a car built with the improved bumper beam, intrusion was considerably reduced and the steering column remained much more stable during the crash.
The evaluation of the Fit is based on the second test and also applies to earlier cars repaired under Honda's product update. This modification will significantly improve protection in small overlap crashes.
