Speedcafe understands both the Chevrolet Camaro and Toyota Supra have hit the trigger set out by the parity review system.<\/p>\n

The new-for-2026 structure requires Supercars\u2019 technical department to undertake an investigation when the trigger is reached.<\/a><\/p>\n

That trigger is the result of a complex, rolling six-race calculation using lap time data from the top finishing cars from each marque.<\/p>\n

Chevrolet runners expected to hit the trigger in Taupo and had already been working on an aerodynamic upgrade package it hopes to have in place by next weekend.<\/a><\/p>\n

The fact the Toyota is also potentially in line for upgrades is somewhat of a surprise given Ryan Wood stormed to the marque\u2019s maiden pole and victory on Saturday at Taupo.<\/p>\n

Toyota\u2019s V8 engine, though, is still somewhat of a work in progress, with engine mapping changes understood to have taken place outside official parity reviews.<\/p>\n

Its first win came on a track where chassis balance is said to play a greater role than engine performance, while\u00a0Walkinshaw TWG\u2019s two Supras were notably more competitive than Brad Jones Racing\u2019s trio.<\/p>\n

Supercars has stressed the trigger system only requires it to undertake an investigation, with no guarantee that changes will be made.<\/p>\n

The reintroduction of the trigger system this year is an attempt from Supercars to formalise a structure around parity reviews.<\/p>\n

It does, though, create debate around what is technical parity and what is sporting parity.<\/p>\n

Ford\u2019s flying start to the new season has followed its poaching of Triple Eight from General Motors, which ensured it has the lion\u2019s share of top teams and drivers.<\/p>\n

Mustangs have won seven of the nine races to date (three for Triple Eight and four for Dick Johnson Racing), with Chevrolet (Team 18) and Toyota (Walkinshaw) one each.<\/p>\n

Supercars remains a technical parity formula, based on the principal of equalising key parameters around aerodynamic and engine performance between brands.<\/p>\n
