Wind tunnel testing is crucial for Formula 1 teams as they develop their cars throughout the season in order to stay competitive.
Testing restrictions existed prior to F1's intervention, but in a push to implement a more level playing field, the sport brought about more radical changes in 2021.
The Aerodynamic Testing Restrictions (ATR) is a handicap system that resets every six months and provides those lower in the standings more testing time.
As a result, the further up a team finishes in the Constructors' Championship results in fewer testing hours for the following campaign.
Viewed by others:
Haas finished last in 2023 and now has 115 per cent of available time while champions Red Bull are allocated only 70 per cent.
Despite its restrictions, the Milton Keynes-based squad has been able to maintain a dominant front-running position across the last two seasons.
Below, see how many wind tunnel hours each team has this year.
