F1 Team Facing 'Inevitable' Action Which Will Impact Australian Grand Prix

A Formula One team is at risk of serious action against them ahead of the season opener in Melbourne.

The 2026 Formula One season is now just over three weeks away and anticipation is higher as ever with a new set of regulations expected to cause a major shake up in the standings.

Currently, all 11 teams are taking part in the first of two weeks of televised testing sessions at the Bahrain International Circuit, having already done some testing behind closed doors in Barcelona.

So far, rumours and results from testing have suggested that Mercedes will be the strongest team in 2026 ahead of the likes of Red Bull, McLaren and Ferrari.

But it's now been revealed that it is looking 'inevitable' that one of the top teams will be dealt a major blow ahead of the Australian Grand Prix.

Ahead of the season getting underway, it's widely been rumoured that Mercedes have built the strongest car, thanks largely to them finding a loophole in the new regulations regarding their engine.

However, later reports have claimed that the FIA were considering banning the loophole, which involves the ratio between the largest and smallest volume in the cylinder of the engine.

And now, a new update from FormulaRacers has claimed that there is a growing belief within the grid that action against the Mercedes engine is now 'inevitable'.

It claims that a decision regarding the engine will be made ahead of the Australian Grand Prix on March 8.

The report comes amid claims that rival manufacturers have come together to push the FIA to take action against an engine which they believes violates the regulations.

It is currently believed that the Mercedes engine is able to increase its compression ratio above the 16:1 limit when the engine is turned on.

When the car is stationary during specific static tests at ambient temperature, which is how the FIA check the cars are legal, the engine is believed to be within this compression ratio, explaining how it has initially been deemed as legal.

But other teams have argued that exceeding the 16:1 ratio limit, on track or anywhere else, is clearly illegal and must be punished.

As it stands, it remains unclear what a punishment against Mercedes would look like and how it could impact them at the Australian Grand Prix.
