Evaluation of the Bumper Standard-As Modified in 1982

摘要

An evaluation of the Bumper Standard was conducted to determine actual benefits and costs and cost effectiveness of changes made in 1982. These changes, effective with the 1983 model year, reduced required damage resistance for passenger car bumpers. The evaluation compares collision damage experience and bumper system costs of 1983/84 models (post-standard modification) to a two year baseline of 1981/82 models (pre-modification). Manufacturers were selective in implementing the new minimum requirements, with only 35 percent of the cars sold in the U.S. in 1983 being equipped with bumpers that were changed in a way which reduced collision damage resistance when compared to the predecessor 1981/82 models. By the 1984 model year, slightly over 50 percent of models sold were equipped with bumpers changed in comparison to 1981/82 models. The conclusions are: (1) The costs to consumers have not changed as a result of the modification of the bumper standard from 5 to 2.5 mph; (2) The net effect, over a car's 10 year life, is a small increase in repair cost, which is offset by a reduction in the cost of the bumpers; and (3) The change in the bumper standard has not affected the protection of safety-related parts.
