Next year will be the first that the stock car series does not feature sedans, marking a 45-year first for the category.
Instead, Stock Car’s three manufacturers – Chevrolet, Toyota, and Mitsubishi – will field compact SUVs.
That’s in line with trends in the local automotive landscape as sedans become less popular while sport utility vehicles and crossovers gain traction.
After eight years, Chevrolet will ditch its Cruze and instead utilise the Tracker – a car not currently sold in Australia.
Prior to the switch, Toyota used its Corolla sedan but will switch to the Corolla Cross variant.
Mitsubishi returns to the Stock Car Pro Series in 2025 after a 16-year hiatus with its Eclipse Cross.
Toyota and Mitsubishi have yet to reveal their machines beyond early renders.

Chris Rego, marketing director at General Motors South America, said Stock Car’s move towards compact SUVs is in line with market trends.
“The choice of Tracker as Chevrolet’s representative in Stock Car is an innovation that reflects the consumer’s desire for SUVs, a segment that has recently come to dominate the Brazilian market,” Rego explained.
“Furthermore, the Tracker is the best-selling SUV in South America and the competition reinforces the product’s successful image.”
In line with the move away from sedans, the Stock Car Pro Series has ditched its 6.8-litre V8 powerplant for a turbocharged 2.1-litre four-cylinder engine.

The new engines make 500bhp (370kW) and rev to 7600 rpm with drive going to the rear wheels.
The cars run an Xtrac six-speed sequential gearbox operated by paddle shifters.
The cars feature DRS, weigh 1100kg, and have a 2750mm wheelbase.
Although the use of crossovers and compact SUVs is new for the Brazilian series, it’s not an entirely new concept.
The Ford Puma is prominent in the FIA World Rally Championship and NASCAR has begun experimenting with SUV platforms with its recently revealed all-electric prototype.
The short-lived Jaguar I-Pace eTrophy became the first high-profile SUV-based racing series in support of the FIA Formula E World Championship.
Could Supercars eventually follow suit?
Down Under, the championship has support from Ford with its Mustang and Chevrolet via its Camaro – but getting more manufacturers involved might require Supercars to move away from its coupe focus.
