- The work considers changes occurred in the features of the supporting structure in three categories of cars, namely: with the self-supporting body, framed body an intermediate structures between these two solutions. The area of analysis includes the length of deformation (crush) of the front al part of the car after collision with a rigid obstacle (barrier). The range of deformation is a significant factor of the passive car safety and indicates the efficiency of fulfilling the protective function for the passengers. The work shows absolute and relative (percentage and unit) variations of the car deformation, depending on the year of manufacture, including the period of 1980 - 2010. Marked trend lines indicated general nature of the deformation range variations together with the improvement of the car supporting system structures. The course of the trend line has been calculated on the basis of average deformation length values, calculated in defined periods of vehicle manufacture. Selected sections of time result from the division of the period of analysis 1980 - 2010 into six parts. The analysis of the deformation length of the frontal part of passenger cars, SUVs and pickups has been combined with simultaneous evaluation of total car length variations and their weight values. The car weight directly affects the kinetic energy of the impact so it has a significant influence on the range of deformation of the car front during collision with an obstacle.
