Summary

This report, conducted by Pioneer Engineering & Manufacturing Company for the National Highway Traffic Safety Administration (NHTSA), evaluates the consumer cost and weight impacts of complying with Federal Motor Vehicle Safety Standards (FMVSS) 201, 203, 204, and 210. The study specifically analyzes the economic effects of standards governing occupant protection in interior impacts (201), steering control impact protection (203), steering control rearward displacement (204), and seat belt assembly anchorages (210). The research aims to quantify the magnitude of the economic impact on the automotive industry and consumers resulting from these safety regulations, while also assessing how trends such as vehicle downsizing, weight reduction, and the adoption of front-wheel drive influenced compliance costs. The methodology employed a detailed "teardown" analysis of components from a sample of twelve high-volume passenger cars representing various size classifications, including standard, intermediate, compact, and sub-compact models from domestic and foreign manufacturers. The study compared pre-standard designs with post-standard implementations to isolate costs attributable to regulatory compliance. Researchers utilized a "Micro-Cost Analysis" to determine variable manufacturing costs—covering material, labor, burden, and assembly operations—for specific components like steering columns, shafts, and mounting brackets. These component costs were then scaled using a "Macro-Analysis" of manufacturer financial statements and dealer discount data to estimate wholesale and consumer price effects. All cost data were based on third-quarter 1984 economics. The findings reveal significant variation in compliance costs depending on design choices rather than vehicle size or steering system type. For FMVSS 203 and 204, manufacturers adopted various energy-absorbing steering systems, such as collapsible columns and intermediate shafts with universal joints, to limit chest force and rearward displacement. The weighted average safety system costs for specific components were calculated: $1.88 for shift tube assemblies, $1.04 for steering column mounting brackets, $2.84 for column jackets, $4.04 for steering shafts, and $8.15 for intermediate steering shafts. The study noted that design selection had a greater impact on cost than the type of steering system (worm gear vs. rack and pinion). For instance, the AMC Alliance achieved lower costs through efficient design features, such as a one-piece steering shaft and rubber bushings, while Chevrolet offered the least costly systems for standard and intermediate cars among the major domestic manufacturers. The significance of this report lies in its detailed quantification of the economic burden imposed by federal safety standards on vehicle manufacturers and consumers. By breaking down costs to the component level, the study provides NHTSA with empirical data on the financial implications of FMVSS compliance. It highlights that while safety standards necessitate specific engineering changes, the resulting costs are heavily influenced by individual manufacturer design strategies. The report serves as a critical resource for understanding the trade-offs between safety regulation, manufacturing costs, and consumer pricing in the automotive industry during the mid-1980s.

Key finding

The weighted average safety system cost for steering column mounting brackets was $1.04, while intermediate steering shaft assemblies averaged $8.15, with design choices driving cost variations more than vehicle size or steering type.
