BMW accelerates vehicle development and quality control
BMW Group faced slow vehicle development and quality analysis due to manual data transfer and on-premises processing. To solve these bottlenecks, BMW developed a mobile data recorder (MDR) IoT device and rolled it out to thousands of development cars. The MDR automatically transmits data over cellular networks to Azure cloud for rapid aggregation and analysis. Azure AI Services and Azure OpenAI Service, including a GPT-4 powered copilot, allow engineers to query data using natural language, speeding analysis and insight delivery. The cloud-based platform leverages Azure Kubernetes Service, Azure Data Explorer, and Azure IoT Hub to manage large volumes of automotive development data. Power BI democratizes data access with business-focused visualizations. The new system reduced time to insight from days to hours or minutes, enabling real-time troubleshooting and faster prototype iterations. As a result, BMW achieved higher development quality and faster innovation cycles, ensuring better reliability for future car models. The platform's architecture is regarded as a critical asset for all of BMW's car development since 2020, and future plans include exploring Microsoft Fabric for unified analytics.

Architecture
Mobile Data Recorder (MDR) IoT devices in each BMW development car transmit telemetry over cellular networks to Azure IoT Hub. Data is ingested into Azure Data Explorer for time-series analytics, managed and visualized using microservices on Azure Kubernetes Service and Power BI dashboards. Engineers interact with a copilot web app (using Azure OpenAI Service, GPT-4) for natural language queries. Backend and frontend are deployed as managed microservices on AKS; conversations and knowledge base logs are stored in Azure Database for PostgreSQL. Future plans involve potential Microsoft Fabric integration for unified analytics.
