🔧 2025 Spanish GP Preview: Massive Upgrades & Key Technical Changes Could Reshape the Season

As we wrap up a thrilling triple-header, all eyes now turn to 2025 Spanish GP - arguably the most pivotal race of the 2025 F1 season so far. Why? Because Spain isn’t just another GP. It’s the proving ground for game-changing upgrades and the battleground for the controversial flexi-wing Technical Directive (TD) that’s set to shake up the pecking order.

In this post, we break down:

• What the TD means for each team

• Which cars are receiving major updates

• Who could gain (or lose) the most pace in Spain

  
  

Let’s dive in.

🛑 The Technical Directive That’s Rocking the Grid in the 2025 Spanish GP

Starting in Spain, FIA’s new TD drastically limits front wing flex. While some teams leaned heavily on flex for cornering grip and straight-line speed, they’ll now have to adapt. Expect visible design tweaks, performance shifts, and potential setbacks for teams caught out.

🛠️ Who's Bringing What? Team-by-Team Breakdown

❌ No Major Updates Expected:

• Haas: Already upgraded in Imola, still struggling with corner entry.

• Racing Bulls: Rebounded to midfield, but no new parts for Spain.

• McLaren: Quiet on the upgrade front, but expect changes to their very flexy front wing due to the TD.

🔴 Heavy Hitters: Major Upgrade Packages

Mercedes

• 💥 New floor, diffuser, and rear suspension tweaks

• Their previous front wing exploited flex to the max—now under scrutiny.

• Toto Wolff claims the team finally understands the direction they need to go.

Ferrari

🟥 Biggest upgrade of the season incoming

• New front wing (first since 2024 Singapore), floor changes, and brake duct tweaks already improving rear tire degradation.

• Spain won’t be their “make-or-break,” but it could expand their setup window drastically..
