The international car manufacturer Stellantis designs and produces vehicles for fourteen brands. Some brand characteristics satisfy both the European and North American market (e.g., Jeep), while others primarily target one market or the other. Efforts have been made recently to harmonize design and development processes within the global company. The cornerstone of this project is the subjective assessment procedure performed on the dynamic driving simulator, a newly developed technology that reduces time and cost during the development phase of a new car model. The technology can be used prior to the production of physical prototypes, allowing the assessment of handling and dynamic qualities continuously during the design phase as various parameters are changed.
