Already set for a season of change, a major shake-up looms for Supercars in 2020 as chief executive Sean Seamer mulls the sport's potential.
In 2019, the Ford Mustang will make a hotly anticipated Supercars debut along a shorter grid - and one that doesn't feature Craig Lowndes for the first time this millennium.
But in 2020, the possibility of a summer series, an IndyCar tie-up, new formats and more night racing loom large.
"It's all about making it easier for people to come in and out of the sport and enjoy it rather than having to have a PhD in Supercars to understand what's going on," Seamer said from the sport's season launch on Wednesday in Melbourne.
