This master’s thesis concerns a new instep for the LowEntry truck segment of Scania. The current instep has major ergonomic, safety and aesthetic issues. The solution is manufactured by an external supplier therefore it does not have a coherent design under the Scania brand. Regarding the problems a study about the truck segment, the existing solutions in Scania and the market, the standard and regulations as well as a user analysis has been conducted. The set requirements gotten from the study has been used as a base for the design proposals in the next phase. Different concepts both on steps and step wells and finally an instep as a design were proposed. The last phase has been the development of the potential solutions, choosing the best set, designing it in details and progressing to a complete and tested prototype.
