Supercars’ plan calls for a combined field of the main Supercars Championship grid and the second tier Dunlop Super2 cars for an all-in spectacular under lights at Sydney Motorsport Park.

The event would use the shorter 2.8km South circuit. It was a variation of this circuit which was used the last time the Supercars raced under lights at the venue, in 1996.

Additional circuit lighting would be required in order for the event to be ‘TV friendly’. Supercars is said to be investigating the cost of temporary additional lighting while awaiting the circuit’s own proposal for permanent lighting to be signed off by the NSW government.

The event would probably not count for championship points, according to Supercars CEO James Warburton.

“What we want to do is create something unique,” Warburton was quoted on Supercars.com.

“You’ve got to continue to innovate in your sport and you’ve got to push the boundaries and find new levels of interest.

“It might be a made-for-TV event that we’d run mid-week, on say the Wednesday and Thursday nights, or be based around fan activation at the event.

“It could be non-championship which allows a lot more freedom in terms of the format, including opening it up the Super2 teams as well.

“A lot of things have already been done with reverse grids and things like that, but combining the fields for a series of heats and a final is among what’s in the mix.

“At the moment there’s a few pieces in the puzzle that need to come together to get to where we need to be to make it a reality.

“At this stage it’s all conceptual. It is a work in progress which we hope to bring to life in 2018.”

“We’ve already got light at a level which is commensurate with suburban sporting grounds, but for broadcasting you need significantly more.

“Bringing in temporary light towers and positioning them well, it’s possible to get them up to minimum pixels from a broadcasting point of view."
