In this Gap Analysis and Technology Forecast Report, we highlight the academic and industrial perspectives on the key building blocks required to be completed to define, implement, and evaluate the software-defined vehicle concept in practice. We focus primarily on areas where significant gaps can be found. First, we discuss proposed SDV architectures and their challenges in terms of interoperability and paradigm shift from monoliths to microservices. Second, we analyse vehicles as a part of a broader continuum with other vehicles, roadside infrastructure, and edge-cloud computing capabilities, as future API developments will also require changes in the supporting systems and resources. Thirdly, we address validation and verification as an integral part of the SDV development pipeline, as vehicular software will be compatible with real-world complexities.
