Stewards fine Racing Bulls after Lawson's CDS failure halts sessions
Liam Lawson's Racing Bulls VCARB03 suffered a clutch-disengagement system (CDS) failure during FP1 at the Canadian Grand Prix at Circuit Gilles Villeneuve, with stewards determining a ruptured hydraulic joint caused a hydraulic leak that stopped the car and prevented the CDS from operating. When marshals pressed the exterior CDS button, it failed to release the clutch, leaving the car immobile for around 15 minutes, per Source 1; Crash.net reported the failure happened about 10 minutes into the sole practice session. The session was initially placed under a Virtual Safety Car before being upgraded to a red flag, with stewards noting the fault forced the red flag rather than allowing a faster recovery under VSC. Marshals attempted to push the stationary car and one mistakenly pressed an on-board camera button instead of the CDS control — actions the stewards criticized.
The stewards described the fault as "a serious matter," finding the CDS on Lawson's car was performing dual roles as both a clutch-disengagement system and an anti-stall function — a design the FIA Technical Delegate had previously flagged, with Racing Bulls reportedly having been warned about it back in 2025. Regulations, the stewards noted, require the CDS to operate even if a car's primary hydraulic, pneumatic, or electrical systems fail. Racing Bulls were fined €30,000, with €20,000 suspended for 12 months and €10,000 payable immediately, though Source 1 reported only a €10,000 fine. The stewards urged practical marshal training to supplement existing FIA recovery guidance, and the FIA said it would work to improve marshal training going forward.
The fallout cost Lawson his on-track program: the car could not be repaired in time for Sprint Qualifying or the Sprint, and he completed only five laps across FP1 and Sprint qualifying. The combined ruling and reporting underscored both a technical non-compliance with safety regulations and procedural shortcomings in incident response, prompting enforcement action and recommended follow-up.
