Marelli Celebrates 300th F1 Race Milestone with FIA-Co-Developed Official Data Logger SDR, Debuts AI-Powered Next-Gen SDR 5

Marelli's FIA-co-developed F1 official data logger, the Survival Data Recorder (SDR), reached a significant milestone at the 2026 Monaco Grand Prix. The SDR achieved its 300th official race deployment. At the same time, the latest evolution of the system, 'SDR 5'—featuring AI integration and numerous functional enhancements—made its competitive debut.

To commemorate this milestone, Marelli Motorsport Head Riccardo de Filippis held a special ceremony, presenting FIA President Mohammed Ben Sulayem with a limited-edition 'SDR 4' to celebrate the 300-race journey.

The SDR is a critical electronic unit installed in every F1 car. It plays a vital role in enhancing race safety and ensuring compliance with technical regulations by providing detailed data to the FIA in real time.

Comment from FIA President Mohammed Ben Sulayem:
"The SDR is an extremely important asset for Formula 1. It delivers high-quality data essential for safety and reliable enforcement of regulations. Reaching 300 races in F1 is a remarkable milestone and a testament to our strong collaborative relationship with Marelli.
Innovation lies at the heart of motorsport. Advanced technologies like the new SDR 5 will play an increasingly crucial role in supporting FIA race officials by delivering faster, more accurate, and more comprehensive data."

Comment from Marelli Motorsport Head Riccardo de Filippis:
"Real-time data analysis is critical in cutting-edge motorsport. Our SDR has now supported over 300 F1 races, contributing to data collection, transmission, and technical regulation compliance. This is truly a milestone worth celebrating. With the introduction of the new SDR 5, race officials will gain access to information that is more accurate, reliable, and actionable than ever before. We will continue to drive innovation alongside the FIA and support the evolution of Formula 1. We look forward to continuing to push the boundaries of technology."

The system collects data from a wide range of sensors and electronic control units installed on the car, including accelerometers, temperature, pressure, and speed sensors. During operation, the SDR stores vast amounts of data with high reliability and fast write speeds. It further cleans and processes the data in real time using advanced algorithms and hardware filters. The collected data is then transmitted in real time to FIA race officials via dedicated communication channels.

By quickly detecting and recording abnormal movements or specific events, the system enables rapid root-cause analysis and helps prevent potential issues. This capability is essential for accurately recording incidents and verifying compliance with race regulations.

Notably, the newly introduced 'SDR 5' has achieved significant technological advancements, aligning with the new F1 regulations starting in 2026. While maintaining compatibility with previous configurations, it features ten high-speed CAN FD interfaces and a new in-vehicle Ethernet port, greatly enhancing communication capabilities.

Additionally, it supports up to 5,000 channels, further increasing the speed of critical data collection. Data transfer volume and speed have doubled compared to previous versions, enabling more efficient data acquisition.
Advanced new filters and monitoring functions have improved data accuracy, and new capabilities for measuring voltage and current have been added. The adoption of the latest drivers (control circuits) allows for more flexible actuator control, enables direct current reading, and simplifies installation. Furthermore, the integration of AI (Artificial Intelligence) enables advanced data analysis, while the unit’s weight reduction contributes to overall vehicle performance improvements.

With the introduction of SDR 5, Marelli Motorsport deepens its technical contribution to F1 and the FIA, continuing to support advancements in safety and regulatory compliance. Leveraging over a century of experience in top-level motorsport, Marelli Motorsport will continue developing cutting-edge technologies and supplying them to all major teams and championships.
