The Mercedes-Benz CLA has been named Euro NCAP’s Best Performer of 2025 after achieving the highest overall safety score among 49 vehicles tested this year, highlighting the growing influence of advanced driver assistance and artificial intelligence in vehicle safety assessments.
Euro NCAP said the CLA led the field across its weighted evaluation categories, which include adult occupant protection, child safety, vulnerable road user protection and safety assist systems. Only vehicles that achieve a five-star rating with standard equipment are eligible for Best Performer recognition.

The result reflects the integration of NVIDIA’s DRIVE AV software and its Halos safety architecture in the CLA. The system combines an AI-driven end-to-end driving stack with a parallel, rules-based safety stack, designed to provide redundancy across sensing, planning and vehicle control functions.
Euro NCAP, Europe’s independent vehicle safety authority backed by governments, motoring organisations and consumer groups, places particular emphasis on crash avoidance technologies in its “Vulnerable Road User” and “Safety Assist” categories. These cover features such as automatic emergency braking, lane-keeping assistance and speed control, which increasingly rely on software and sensor fusion.

According to NVIDIA, the CLA also uses the DRIVE Hyperion platform, which incorporates sensor diversity and hardware redundancy, alongside the Halos safety framework. That framework spans hardware, software and development processes and is intended to support fault tolerance and regulatory compliance for advanced driver assistance and automated driving systems.
Independent validation of the platform includes ISO 21434 cybersecurity certification and ISO 26262 Automotive Safety Integrity Level D conformance from TÜV SÜD, as well as a UNECE-related safety assessment by TÜV Rheinland.

Mercedes-Benz said the CLA’s performance reflects several years of joint development with NVIDIA, including extensive simulation-based safety validation. NVIDIA’s development approach uses cloud-based training and simulation to test rare and high-risk scenarios that are difficult to reproduce safely in real-world driving.
Mercedes-Benz Chief Executive Ola Källenius has previously said that achieving top Euro NCAP scores increasingly depends on state-of-the-art driver assistance systems, as software capability becomes as critical as mechanical design in modern vehicle safety.
