The 2025 Formula 1 season has largely matched predictions. Initially, McLaren emerged as the dominant team. However, the FIA’s latest updates might change everything. Recently, these new FIA Technical Directives (TDs) could affect performance areas where some teams currently excel.
How the New Rules Affect Car Performance
Can McLaren Keep Winning?
Before the Emilia Romagna Grand Prix, McLaren won five of the season’s first six races, showing impressive speed and strategy. Two main factors explain their success:
- Better Car Design – Specifically, they mastered flexible front wings.
- Tyre Care – Notably, they managed Tyre wear better than rivals.
Then at Imola, Red Bull surprised everyone. Max Verstappen won easily. His team boss said it was their first clear speed advantage over McLaren this year. This happened right as the new FIA rules came out.
What the New Rules Say

The FIA made two big rule changes before Imola:
1. Rules About Car Height
Some teams ran their cars very close to the ground. The new rules make them raise their cars a bit. This might slow down teams that relied on this trick.
2. Rules About Tyre Cooling
Teams can’t use special tricks to cool tyres anymore. McLaren might have used these methods. Now everyone must play by the same rules.
Did the Rules Hurt McLaren at Imola?
Some think the new rules slowed McLaren down at Imola. But experts say the track just suited Red Bull better. The long-term effects of the rules could be bigger.
More Changes Coming Soon
Another rule change (called TD018) is coming for the Spanish GP. It will affect front wings. Teams that pushed the limits might lose speed. Others could gain.
What This Means for the Season
The new FIA rules could dramatically change race outcomes. Currently, McLaren remains strong, but recently Red Bull proved they can challenge. Consequently, as teams adapt, expect more surprises. Ultimately, these changes guarantee an even more thrilling season.
