The Virgin Australia Supercars Championship has announced its plans to improve the aerodynamic homologation testing next season when downforce will also be reduced on all rides.

These plans will work in conjunction with the in-season changes made in 2019 for parity.

The new aero rules will see downforce reduced by nearly 15 percent in a bid to improve race quality. All competing models will also be retested with an improved process during the upcoming offseason.

The 2020 VCAT homologation test will measure downforce at various car heights and will utilize an active suspension system developed by the series’ technical department and technology partner D2H to measure downforce with active dampers.

The Virgin Australia Supercars Championship has also confirmed its 2020 revised engine rules, which are aimed at reducing costs and improving longevity.

Mandated parts include a control ring and revised rocker ratio, with rebuilds capped at three per season. Supercars will also adjust its overall horsepower limit, referred to as Accumulated Engine Power.

"There wasn't a single team doing under four rebuilds and it was a sort of easy objective for us to try and get that down to three. The easiest way for us to do that equally for everybody was to change the rocker and ring package. That will lose approximately 14, 15 horsepower equally for everybody. And it'll just de-stress the engine a little bit,” Supercars’ Head of Motorsport Adrian Burgess explained to supercars.com. “Part of the thing the teams were doing, they all migrated to a really expensive ring package that gave them two horsepower. But it actually degraded a lot quicker. We're not re-inventing the wheel or anything, we are going back to an older ring package for everybody. It's $390 as opposed to $2,000 a set.”

In addition, drive-by-wire throttle activation will remain optional in 2020. Currently, all teams use mechanical cables.
