The Fédération Internationale de l’Automobile (FIA) has officially released the technical documentation and summary of all car updates brought by Formula 1 teams to the Hungarian Grand Prix, the thirteenth round of the 2025 season.
Among the leading teams, Oracle Red Bull Racing was the only one to introduce new components specifically developed for the event at the Hungaroring. The Milton Keynes-based outfit implemented an updated front wing flap, designed to generate additional downforce on a high-downforce track like Budapest. In addition, Red Bull revised the design of the front corner to improve brake cooling, an area of particular importance in hot weather conditions expected during the weekend.
Aston Martin Aramco Formula One Team also made a minor adjustment, updating a previously used aerodynamic configuration by adopting a more aggressive version of the front wing to match their high-downforce rear wing chosen for the Hungarian round.
Meanwhile, the Visa Cash App RB team focused on two specific technical areas: aerodynamic refinement and thermal efficiency. They revised the front corner to enhance airflow management around the brake drum and expanded the cooling louvres to deal with the elevated temperatures forecast for the Hungarian Grand Prix.
This phase of the championship was not expected to bring major upgrade packages. The busy calendar and the proximity of the summer break are encouraging most teams to save their most significant updates for later races, such as the Italian Grand Prix at Monza, where the final developments of the season are traditionally introduced.
Below is the complete list of modifications made by each Formula 1 team to their 2025 challengers:

Red Bull Racing
Red Bull Racing introduced two targeted developments tailored specifically for the Hungarian Grand Prix. Both updates were aimed at optimising performance under the high-downforce demands of the Hungaroring and improving thermal reliability. The front wing was updated with a longer chord flap to increase aerodynamic load, while the front corner was redesigned to enlarge and reshape the brake duct, enhancing cooling efficiency under high-temperature conditions.
| Component | Purpose | Differences | Description |
|---|---|---|---|
| Front wing | Performance – local load | Front wing flap element with a longer chord | Due to the expected high rear wing downforce at the Hungaroring circuit, a second element of the front wing flap has been produced with a longer chord, which adds aerodynamic load to the front wing. |
| Front corner | Reliability | Enlarged and reshaped brake duct intake and outlet | To deliver increased airflow into and out of the wheel bodywork and enhance brake cooling, the intake has been enlarged compared to previous versions, and the outlet duct has been reshaped to match the new inlet profile. |

Aston Martin Aramco Formula One Team
Aston Martin introduced a new specification of their front wing, specifically developed for the characteristics of the Hungaroring. Compared to the previous version, the updated front wing features a more aggressive flap configuration. The goal was to optimise the aerodynamic balance in conjunction with a high-downforce rear wing, enhancing the car’s ability to generate downforce and improve stability through the circuit’s low- and medium-speed corners.
| Component | Purpose | Differences | Description |
|---|---|---|---|
| Front wing | Circuit-specific – aerodynamic balance range | More aggressive front wing flap than in previous event | The more aggressive design increases the total downforce generated by the wing, intended to be used in combination with the high-downforce rear wing selected for this race. |

Visa Cash App RB
Visa Cash App RB made targeted improvements in two key areas ahead of the Hungarian Grand Prix: airflow conditioning and engine cooling. The front corner was redesigned, particularly around the front brake drum area, to better guide airflow toward the rear of the car and improve aerodynamic performance. At the same time, the team adopted a larger cooling louvre panel to address the circuit’s high cooling demands, ensuring better thermal dissipation for the power unit.
| Component | Purpose | Differences | Description |
|---|---|---|---|
| Front corner | Performance – airflow conditioning | Updated front corner surfaces | The shape of the front brake drum components has been modified to improve the conditioning of airflow toward the rear of the car. |
| Cooling louvres | Circuit-specific – cooling range | Larger louvre panel | The louvre panels used on circuits with high engine cooling requirements have been enlarged to enhance thermal dissipation capacity. |
