FIA to introduce AI and advanced positioning to detect track limits in 2026

For years, track limits have remained one of Formula 1's most contentious battlegrounds. Drivers push boundaries seeking marginal gains, teams vigorously defend their drivers, and stewards navigate an exhausting maze of disputed calls. The 2023 Austrian Grand Prix exemplified this chaos, forcing officials to review over 1,000 suspected violations in a single weekend—a staggering workload that exposed the urgency for technological intervention.

From manual chaos to automated intelligence

The FIA's computer-vision system, developed in partnership with Catapult, now automatically detects track-limit infringements by recognizing a car's silhouette and analyzing its behavior against predefined reference points. Previously, officials relied on small teams stationed at trackside corners, a laborious process that invited inconsistency. Today, approximately 95% of cases are processed automatically, with only 5% requiring manual steward review—a seismic reduction in workload.

The ECAT revolution: every car, all turns

The breakthrough lies in the Every Car All Turns (ECAT) system, which measures every vehicle's behavior against an idealized reference model using both positioning data and micro-sector timing information. Rather than relying solely on camera feeds—which inherently have coverage gaps across various circuits—ECAT employs advanced geofencing and precision positioning systems to create a real-time "digital twin" of on-track action.

When a car deviates from the optimal racing line, it necessarily covers additional distance, triggering a detectable change in sector timing. RaceWatch cross-references this telemetry data to pinpoint exactly where a violation occurred, circumventing the need for exhaustive camera analysis. High-performance GPUs now enable distributed processing across the FIA's network infrastructure, allowing instantaneous verification of every lap.

Redefining objectivity in motorsport

By eliminating subjective judgment from the equation and anchoring decisions in objective positional and timing data, the FIA fundamentally reframes how Formula 1 polices its most disputed regulation. Whether this technological revolution finally quiets the perpetual chorus of track-limits complaints remains to be seen—but for the first time, the evidence will be irrefutable.
