This weekend’s final round of the 2018 RXAus.com.au Australian Rallycross Championship at Winton is set to feature a total of 30 cars.

The field consists of multiple classes, with the Open class topping the billing and supported by All-Wheel-Drive Production, Two-Wheel-Drive Production, Under 1.6 Litre, Aussie cars, and the brand-new RXAus Sprint Series.

Four entries from the SXS (Side-by-Side) Australian Championship will also make their RXAus debut in a standalone class.

The RXAus Sprint Series features Autocross-specification cars competing against the clock, two at a time.

Justin Dowel (UP&GO VW Polo), Arron Windus (Hyundai I20), and Darren Windus (Hyundai I20) are expected to battle for Open class honours.

Troy Dowel, son of Justin, will not compete given he is currently undergoing chemotherapy, but has already wrapped up that title.

Meanwhile, Marcus Walkem will debut an AP4-specification Peugeot rally car in the Open class.

The round will be run to a new format common in European rallycross series, namely a heat race format in which the three heats start with progressive grids.

There will be four-car grids in the heat races with six cars progressing to the semi-finals and then final.

The event takes place this Saturday (November 10).
