What Happened
official Formula 1 events
The Marelli Surveillance Data Recorder (SDR) reached 300 official F1 events at the Monaco Grand Prix.
The SDR is a core electronic unit installed on all Formula 1 cars that acquires data from sensors including accelerometers, temperature, pressure, and speed. It stores large volumes of data with high reliability and fast write speeds, enabling real-time analysis and transmission to FIA officials. The system detects events and anomalies to support diagnostics, accident recording, and compliance verification.
- Complies with F1 2026 regulations and introduces ten high-speed CAN FD interfaces and new Automotive Ethernet ports while maintaining backward compatibility.
- Supports up to 5,000 channels with faster sampling rates and doubled bandwidth and speed for more efficient data collection.
- Integrates artificial intelligence for advanced data analysis and includes new voltage and current measurement capabilities, advanced filters, and reduced mass.
“The SDR is vital for Formula 1, providing the FIA with the high-quality data needed to support safety and ensure regulatory compliance. Reaching 300 Formula 1 events is a significant milestone and a testament to the strength of our collaboration with Marelli. Innovation has always been at the heart of motorsport and advanced technologies such as the new SDR 5 will play an increasingly important ro”
Why this matters
The SDR provides real-time data to support safety and regulatory compliance in Formula 1, and the SDR 5's enhancements and AI will deliver faster, more accurate data analysis, helping officials enforce rules and improve safety.
