A parity investigation is being conducted by Supercars following last weekend’s third round of the 2026 championship at Taupo in New Zealand.
The process is one that is triggered by the category’s parity review system, which is based on a rolling six-race calculation using lap time data from multiple cars of each brand: Ford, General Motors-Chevrolet and Toyota.
Toyota’s Supra activated the trigger following its first Supercars win, when Walkinshaw TWG’s Ryan Wood took his GR Supra to its maiden win at Taupo on Saturday. On Tuesday however, Supercars said that there will be no change to the Toyota following analysis and investigation.
“Please be advised Supercars have concluded the investigation into the Toyota Supra parity trigger and discussed the findings with the Toyota HT,” a note to teams said. “The determination is no adjustment is required.”
That leaves Chevrolet’s Camaro as the car that could possibly be modified for parity purposes, perhaps as soon as this weekend’s fourth round at Ruapuna in New Zealand.
Parity investigations are triggered in the series when a significant performance delta is observed between the three automakers competing in Supercars. Following the investigation, changes are not a certainty – but additional test days can be carried out or further validation work both on- and off-track.

As the teams head to the country’s south island for the first time, Ford Mustangs have won seven of the first nine races of the season, and Chevrolet and Toyota one each. In the drivers’ championship points, Ford drivers occupy eight of the top 12 positions, to two Toyota drivers and two Chevrolet drivers.
At Taupo the best-placed Camaro driver was Anton De Pasquale, who took eighth in the first race and 10th in the second. The Team 18 driver also took Chevrolet’s best results in two of the four races at Albert Park, with ninth in Race 1 and fifth in Race 3. The other Camaro drivers to take best finishes at Albert Park were Jack Le Brock (Matt Stone Motorsport), with a fourth and a sixth place at the grand prix circuit.
During the off-season Supercars and the three manufacturers conducted a substantial test programme at the Windshear wind tunnel facility in North Carolina, which Supercars said achieved aerodynamic parity between the three makes.
The championship continues this weekend at Ruapuna near Christchurch, with four races over the three days – one of which as a replacement for cancelled race that was to be held at Taupo last Sunday.
