It's been one of the busiest Supercars off-seasons in recent memory.
In fact, so busy that if you feel like every team has gone through some kind of change before the new season, you aren't mistaken.
Ranging from changes to ownership structures to complete overhauls of driver lineups and everything in between, all 12 teams have experienced some level of change year-on-year.
As the year begins to build to the opening round of the 2026 Repco Supercars Championship at the Sydney 500 from February 20-22, here's a rundown of all the key changes you need to know.

One of the biggest and most visible changes will come at the the head of the field. After a 16-year stint with GM, Triple Eight shift back to Ford, and become the Blue Oval's homologation team. Long-time engine builders KRE Race Engines also depart, with Triple Eight to open an in-house Ford engine program.
