The report confirms that the Phillip Island round will be staged over two 250-kilometre races, with a compulsory fuel drop of 140 litres.

The Auckland SuperSprint, meanwhile, will go from four 100-kilometre sprint races to two 200-kilometre races, which will also include pitstops.

There is a minor change to the Clipsal 500 format as well, with a Top 10 Shootout to be held on both Saturday and Sunday. The series has already confirmed that Clipsal will revert to a two-race event this season.

The report also confirmed Motorsport.com’s reports that qualifying will be run over four legs at the Australian Grand Prix, and that the hard tyre will be no more in 2017. Instead, the Clipsal, Phillip Island, Bathurst, and Auckland events will be run on the soft tyre, while the new super soft will be used at all the other rounds.

At SuperSprint rounds, teams will now only be required to change two tyres, not four, during the 120-kilometre Saturday race.

“The Supercars Commission is extremely focused on the quality of our racing and continues to make positive improvements to formats,” series boss James Warburton told supercars.com.

“These changes combined with our new Dunlop tyres for 2017 will make it another outstanding year of racing for the best Touring Car championship on the planet.”
