Use Cases and Implementations
- German Luxury OEM: Digital Twin for Simultaneous Engineering
A leading German luxury car manufacturer is leveraging digital twins as a core enabler of digital engineering. In contrast to traditional development models that follow a strict, step-by-step process, the company is shifting towards simultaneous engineering, where development phases overlap and run in parallel. This innovative approach integrates several key elements: advanced engineering services, a standardized framework for geometrical data, a semantic layer to interpret complex information, and value synchronization to ensure consistency across systems.
The concept has been successfully demonstrated through a real-world use case involving the synchronization of geometrical and behavioral data in a suspension system, highlighting how digital twins can bridge design and performance in real time.
This OEM has also transformed its production area into a software-defined business model, integrating hardware, software, and digital ecosystems. Their goal is to transition production planning into a fully digital process, allowing real-time production updates and eliminating manual interventions.
Furthermore, the company integrates digital twins with the Industrial Metaverse, enabling simulation, virtual testing, and commissioning throughout the vehicle lifecycle—from development to production and beyond.

User Experience & Future Outlook
A strong UX component is critical for digital twin adoption. This OEM has developed an immersive, interactive UI that dynamically adapts information based on user needs and real-time process states. Users can engage with simulations, test real-world scenarios, and drive innovation in a safe, virtual environment.
Enablers of the Digital Twin Revolution
According to Digital Twin researcher Julian Gebhard, the industry is moving toward integrated federated systems that allow seamless data exchange and synchronization across tools and platforms.
These systems rely on semantic models and knowledge graphs to ensure interoperability and data integrity throughout the product development process. By structuring data as semantic triples (e.g. (Car) → (is colored) → (blue)) data is traversable, transforming raw data to knowledge. Furthermore, it becomes machine-readable, an enabler for collaboration across departments making development more efficient and consistent.
The next step is to use Knowledge Graphs to model product data on a value level, instead only connecting metadata. They enable dynamic feedback loops across systems, so that changes in one area, such as simulation results or geometry updates, can automatically influence related systems. This helps maintain consistency and accelerates iteration during development.
Moreover, when functional data is represented at the value level, it becomes possible to integrate disparate systems such as simulation and CAD tools into a unified, holistic viewer. In this integrated model, any change in geometry in one system automatically triggers updates in simulation parameters and physical properties, ensuring that the digital twin evolves in tandem with the actual product. This dynamic, bidirectional synchronization mirrors the demands of modern, agile product development, where rapid adaptation to change is not just beneficial but necessary for success.
Julian explains that “a growing number of automotive companies are now shifting from traditional databases to knowledge graph-based architectures, enriching their Digital Twins to represent the real world in more detail”.
The Next Evolution: AI-Powered Digital Twins
Based on conversations with digital experts from leading automotive organizations, the next frontier for digital twins lies in AI-driven simulation and automation. Companies are actively exploring areas such as:
- AI Agent Collaboration – Integrating AI-driven decision-making within the Industrial Metaverse
- Physical AI Training – Using synthetic data to test and refine AI models
- Enhanced Transparency – Real-time insights into planning and production progress
- Security & Collaboration – Optimizing process quality through interconnected simulation power
Expert Note: Boris Scharinger from Siemens Digital Industries views AI and Digital Twins as symbiotic technologies:
“AI is an essential tool for data integration, accelerating simulations, extracting insights, and preparing content for the industrial metaverse. System-level simulations and photorealistic visualizations within the industrial metaverse provide an excellent foundation for training industrial AI in real-world control applications.”

FAQ
1. What is a digital twin in automotive manufacturing?
A digital twin in automotive manufacturing is a virtual replica of a physical asset, production line, or entire factory that continuously synchronizes with real-time sensor data. It enables engineers to simulate scenarios such as retooling a body shop or adjusting paint booth parameters without disrupting live production. According to industry estimates, automakers using digital twins can reduce prototype costs by up to 50% and shorten development cycles by 20 to 30 percent. The twin evolves alongside the physical system, incorporating machine learning models that improve prediction accuracy over time. This makes it a foundational technology for both predictive maintenance and process optimization.
2. How do digital twins support predictive maintenance in automotive plants?
Digital twins support predictive maintenance by ingesting vibration, temperature, pressure, and other sensor data from production equipment and comparing it against modeled baselines in real time. When deviations exceed learned thresholds, the system generates alerts before a component fails, allowing maintenance teams to schedule repairs during planned downtime windows. Studies show that predictive maintenance strategies enabled by digital twins can reduce unplanned downtime by 30 to 50 percent and extend equipment life by 20 to 40 percent. The AI layer continuously retrains on new failure modes, making the system more accurate with each operating cycle. This closed-loop approach transforms maintenance from a cost center into a measurable source of productivity gains.
3. What are the biggest challenges when implementing digital twins in automotive manufacturing?
The most common challenges include data integration across legacy OT systems, the cost of deploying sufficient sensor coverage, and organizational resistance to new workflows. Many automotive plants run equipment from multiple vendors with proprietary protocols, making unified data collection difficult without middleware or a unified namespace architecture. Scalability is another hurdle; a proof-of-concept twin for a single robot cell is far simpler than a plant-wide model that must process millions of data points per second. Successful implementations typically start with a high-value use case such as a bottleneck station or a critical press line and expand incrementally. Change management, including training operators to trust and act on twin-generated insights, is equally important to technology deployment.
