Sydney, Australia – A post-race inspection following Race 2 of the Sydney Supercars event has resulted in the disqualification of Walkinshaw Andretti United’s Chaz Mostert and his Toyota Supra. The decision, confirmed by Supercars officials, throws a wrench into the early season standings and underscores the strict adherence to technical regulations within the Repco Supercars Championship.
The disqualification stems from a technical infringement related to the Tyre Pressure Monitoring System (TPMS) sensors. While the team maintains the infraction wasn’t intentional or aimed at gaining a competitive advantage, the regulations are clear: all control tyres must have operational TPMS sensors fitted when used on the car. This incident highlights the critical importance of meticulous preparation and compliance in the highly competitive world of Supercars racing.
TPMS Regulations and the Disqualification
According to Rule D17.1.19 of the Supercars regulations, a Control Tyre must have an operational TPMS sensor fitted to the control wheel whenever This proves fitted to the Car. The official verdict, as reported by Speedcafe.com, stated that the sensors were not fitted at all, regardless of whether a sporting advantage was gained. The fact that the car did not comply with the rules, irrespective of intent, led to the disqualification.
This isn’t simply a case of a malfunctioning sensor; the team failed to install the sensors on the control wheels. Supercars officials emphasized that even if a sensor were to fail due to circumstances beyond a team’s control, the current situation involved a complete lack of installation. The decision underscores the zero-tolerance policy regarding adherence to technical regulations, even in the absence of deliberate intent to cheat.
Impact on the Championship and Broc Feeney’s Victory
The disqualification of Mostert elevates Broc Feeney to the winner of Race 2 at the Sydney Motorsport Park. Feeney, driving for Triple Eight Race Engineering, secured a dramatic victory in a chaotic race, as detailed in reports from Yahoo News Australia. The race was marked by incidents and changing conditions, making Feeney’s win all the more impressive.
The incident also has implications for the championship standings. Mostert’s loss of points will undoubtedly affect his position as the season progresses. The Supercars Championship is known for its tight competition, and even a seemingly minor technical infringement can have significant consequences.
Previous Disqualification and Ongoing Scrutiny
This isn’t the first disqualification to make headlines in the early stages of the 2026 Supercars season. News reports confirm that Mostert Toyota was also disqualified from Sydney Race 2 results. This adds to the scrutiny surrounding the team’s technical compliance.
The Supercars Championship is committed to maintaining a level playing field, and officials have demonstrated a willingness to enforce the regulations rigorously. Teams are expected to ensure their cars meet all technical specifications before taking to the track, and any deviation from the rules will be met with swift and decisive action.
What comes next for Walkinshaw Andretti United is a thorough internal review to understand how the TPMS sensors were overlooked. The team will need to reinforce its pre-race checks and procedures to prevent similar incidents from occurring in the future. The focus now shifts to the upcoming rounds of the championship, where Mostert will be looking to regain lost ground and challenge for the title.
