Marelli has developed an AI-driven System Test Generation (STG) Agent in collaboration with Amazon Web Services (AWS). The tool automates the creation of system test cases from engineering requirements, addressing a traditionally labour-intensive phase of the automotive validation cycle.

The STG Agent was developed alongside the AWS Generative AI Innovation Center and utilises Amazon Nova foundation models, Amazon Bedrock Knowledge Bases and the Strands Agents framework.

The system is designed to integrate with existing requirement management tools and automotive engineering workflows. By automating the analysis of system requirements, the tool identifies expected behaviours and generates structured, traceable test cases to verify that product features align with customer specifications.

As vehicle platforms transition toward software-defined architectures, engineering teams must manage increasing volumes of data and specifications. The STG Agent aims to reduce validation time for new vehicle functionalities, improve consistency in product behaviour across global programmes and accelerate product development for vehicle manufacturers.

Daniele Russo, Head of System Performance Optimisation in Marelli’s Electronics Engineering team, said, “The STG Agent represents an important step forward in how we validate solutions for software-defined vehicles. By combining our engineering expertise with advanced AI capabilities from AWS, we significantly accelerate validation cycles and ensure consistent quality across global programs. This solution enables us to support our customers faster and more efficiently, strengthening the foundation for the next generation of software-defined vehicles.”

Giulia Gasparini, Country Leader of AWS Italia, commented, "Marelli's approach to automating system validation demonstrates the transformative potential of generative AI in automotive engineering. By leveraging Amazon Nova foundation models and Amazon Bedrock, companies are setting new standards for how software-defined vehicles are developed and validated. This solution shows how advanced AI can accelerate innovation while maintaining the rigorous quality and safety requirements that define the automotive industry."

French tier 1 supplier Valeo and open science research lab KE:SAI have launched a joint research collaboration to develop a generalist artificial intelligence (AI) driving system for autonomous vehicles. The partnership plans to publish models, code, weights and datasets as open-source resources.

The initiative brings together artificial intelligence teams from valeo.ai in Paris and the KE:SAI founding team in Tübingen, Germany. The collaboration focuses on training a unified AI model capable of operating across different vehicle platforms, sensor configurations and geographic environments. Initial development will utilise large-scale real-world driving data before integrating reinforcement learning within simulated environments to address rare driving scenarios.

KE:SAI was co-founded by research organisation Kyutai and the ELLIS Institute Tübingen. By making the underlying code, benchmarks and model weights accessible, the initiative aims to provide automakers, component suppliers and academic laboratories with a standardised reference system for autonomous driving research and development.

Marc Vrecko, CEO, Valeo Brain, said, "This open-science collaboration with KE:SAI marks a strategic milestone for Valeo and the broader European automotive ecosystem. By combining our deep industrial and technological expertise in autonomous driving with world-class open-source research, we are establishing a shared foundation to accelerate the development of physical AI and democratize next-generation self-driving technologies."

Andreas Geiger, CEO, KE:SAI, said, "For language models, open source compressed years of progress into months, yet frontier physical AI is still largely closed. Valeo shares our belief that open foundations create more innovation than any closed system ever could. Everything we develop will be open. Every step forward is a step forward for everyone."

Researchers at Chalmers University of Technology, in collaboration with industry partners, have published a study in Nature Communications demonstrating that reconfigurable battery pack architectures can extend electric vehicle battery operational life by more than 20 percent under specific conditions.

In conventional electric vehicle battery packs, cells are wired in a fixed series configuration, meaning the weakest cell dictates the overall capacity, performance and lifespan of the entire pack. The architecture evaluated by the Chalmers engineering team uses integrated electronic switches and a centralised battery management system to monitor individual cells or cell groups. When a cell experiences accelerated degradation or reduced capacity, the system bypasses the degraded unit while electric current continues to flow through the remaining functional cells.

Albert Skegro, a PhD student at the Department of Electrical Engineering at Chalmers University of Technology, said, "They must all move at the pace of the slowest person and stop when that person stops, regardless of how much energy the others have left. With the architecture we have modelled, the battery can instead bypass the cell that is causing problems and continue using the remaining cells."

Changfu Zou, Professor at the Department of Electrical Engineering at Chalmers, said, "Reconfiguration is not an on-or-off choice. It is a spectrum. Where a manufacturer chooses to position itself on that spectrum determines how much of the potential benefit can be realised."

In a representative modelling scenario featuring an 80 kWh battery pack driven 12,000 kilometres annually over an 18.8-year vehicle lifespan, the reconfigurable system deferred battery replacement by approximately 14 months. The researchers noted that the technology yields the highest performance gains in high-voltage vehicles, including 400-volt and 800-volt electric passenger cars and commercial trucks, where higher cell counts in series increase the statistical probability of individual cell variance.

A techno-economic analysis included in the study determined that implementing cell-level switching hardware increases initial pack production costs by approximately nine per cent based on prototype-scale volumes of 1,000 units. The researchers identified an economic break-even threshold at a 12 percent cost increase, noting that volume manufacturing would lower component costs and increase financial viability for fleet operators and private owners. While prototype applications such as Volvo Cars' SmartCell concept and experimental road vehicles exist, mass-production vehicles using reconfigurable battery packs are yet to enter the commercial market.
