Present article presents the results of a current study concerning the low‐velocity impact behaviour of some materials potentially applicable in the automotive industry. The materials tested were as follows: the 1050 H24 aluminium alloy, the Docol 1000 and Docol 1200 high‐strength steel plates and an aluminium/Pecolit sandwich. The impact energy, maximum force, damage size and elastic recuperation were measured. The results for the different materials were compared not only in terms of absolute values, but also in terms of the specific values. The highest values of specific impact energy and specific critical impact force were obtained for Docol 1200, about 62 and 84%, respectively, higher than the values obtained for 1050 H24 aluminium alloy and about 46 and 56% higher than the values obtained for aluminium/Pecolit sandwich. This material was therefore considered the best choice to prevent impact damage.
