The instrument cluster, center display and HUD for Porsche's Enova EV concept, designed in 2025 and validated across five rounds of usability testing with 32 participants. Average task success rose from 79% to 95%; the "set a destination" task from 61.5% to 95.2%; SUS from 61 to 74. Rapoport was Product Manager: he set direction, ran the research and test plan, and coordinated the disciplines through to a tested cockpit, on a team of 31 with a separate Project Manager and three track leads. A concept project, not a shipping Porsche product, run as a sponsored studio with the Savannah College of Art and Design.
