Sandbagging is a term often heard in the opening weeks of a Formula 1 season, specifically during testing sessions.

The word is used by teams, drivers, media and fans to describe someone’s performance – but what does it actually mean?

Sandbagging is when a driver or team intentionally underperforms in their car by slowing it down.

The actual performance of a car is then disguised as it runs below its maximum potential – think of it as like having physical sandbags weighing down the vehicles.

Teams could ‘sandbag’ to lull their rivals into a false sense of security, by producing inaccurate data during testing before showing their full potential in the first race weekend.

Or it could be used to avoid drawing unwanted attention towards their vehicle, preventing rivals from copying successful components so early on in the season.

With new regulations set in place from the 2026 season, teams will want to keep improvements and changes to their cars hidden from others.

So, a team’s maximum performance will most likely only be revealed in qualifying for the Australian Grand Prix this year.

Teams can hide their cars true performance in different ways.

Cars can be loaded with more fuel than necessary, which weighs them down and makes them slower.

Sets of hard tyres could be used during testing, which tend to be the slowest compounds in the range available.

Or teams could tell their driver to lift off at certain points on the circuit to slow down the car.

Sandbagging is not an illegal practice, and tends to be displayed to some extent by most teams across the season.

In race weekends, a driver could be underperforming throughout the three practice sessions, but then use the car’s maximum potential in qualifying to put their car at the top of the start line for the race.
