Racing Bulls have been sanctioned with a €30,000 (£25,900) fine by Formula 1 stewards, with two-thirds of the penalty suspended, following a critical malfunction of the Clutch Disengagement System (CDS) on Liam Lawson’s car during first practice at the Canadian Grand Prix. The failure forced race officials to deploy a red flag after marshals were unable to move the stranded vehicle from the circuit.
The CDS represents a crucial safety feature mounted on the car’s exterior that allows track marshals to disengage the clutch system, enabling quick vehicle recovery when the engine is not operational. According to the stewards’ investigation, a hydraulic leak caused by a ruptured joint triggered both Lawson’s retirement and the subsequent CDS malfunction, preventing the system from releasing the clutch when activated by circuit officials.
Race stewards emphasized the severity of the incident, noting that proper CDS functionality would have allowed the situation to be managed through Virtual Safety Car procedures rather than requiring a session stoppage. The penalty was particularly significant given that Racing Bulls had previously received warnings from the FIA Technical Delegate regarding their CDS design throughout the 2025 season, with concerns raised about the system’s dual-purpose configuration that also interfaces with the car’s anti-stall mechanism.
Additional complications arose from marshal training issues, as Lawson reported to stewards that track officials incorrectly attempted to push his stationary car and mistakenly tried activating an onboard camera button instead of the actual CDS control. The stewards acknowledged these operational concerns and recommended enhanced practical training for race marshals, despite the FIA’s existing comprehensive documentation on single-seater recovery procedures.
