Abstract
Present and proposed safety, damageability, emission and noise regulations require major compromises in other
desirable automobile characteristics. Fuel economy, acceleration, performance and cost all suffer in the design
tradeoffs required. As an example, a subcompact vehicle produced for sale worldwide has been experimentally
modified to meet U.S. vehicle regulations. The sacrifices in customer perceived values are enumerated. The ‘chain
reaction’ effects of mandated changes which add weight to a car are described and quantified. It is concluded that
benefits from motor vehicle design regulations are difficult to measure and a universal need exists for better data
upon which to base future safety, damageability, emission and noise regulations.
