Model-Based Systems Engineering (MBSE) shifts systems engineering from document-centric to model-centric approaches. Its application in student engineering projects remains understudied in European educational contexts despite widespread industrial adoption. This paper investigates MBSE implementation in group-based student engineering projects, examining how systematic requirements management, architectural design, and traceability practices enhance project outcomes and team collaboration. A case study analysed the implementation of MBSE in Silesian Phoenix student association autonomous rover design for Rover Challenge competitions. Data collection included project documentation and technical artefacts (SysML models, requirements matrices, design specifications) across a 24-month project cycle. Structured MBSE implementation demonstrated significant improvements: requirements clarity increased, design traceability achieved much higher coverage, and interface incompatibilities were detected during the design review rather than the integration phase. Critical success factors included early methodology training, dedicated configuration management, and formal stakeholder validation. MBSE provides an effective pedagogical framework for engineering education, developing systems thinking capabilities while improving project execution. The study identifies implementation barriers and provides practical recommendations for educators integrating MBSE into project-based curricula.
