Lewis Hamilton, Fernando Alonso, Andrea Kimi Antonelli and Carlos Sainz, prominent drivers in Formula 1, will face a challenging start in the 2025 Belgian Grand Prix, scheduled for this Sunday, July 27, at the Spa-Francorchamps circuit. After a qualifying session marked by underwhelming results, with early eliminations in Q1, the Ferrari, Aston Martin, Mercedes and Williams teams chose to make significant changes to the cars during the parc fermé regime, violating the FIA (International Automobile Federation) rules. These alterations, which included engine component swaps and suspension adjustments, resulted in penalties that force the four drivers to start from the pit lane, a decision that promises to impact their race strategies on a circuit known for its technical demands and unpredictable weather conditions.
The teams’ decision reflects a common strategy among drivers starting at the back of the grid: seize the opportunity to install new components, even if it incurs penalties, aiming for greater competitiveness in future races. In the case of Hamilton, Alonso and Antonelli, the changes exceeded the FIA’s allowed substitution limits for the season, while Sainz was also penalized for unauthorized modifications. The Spa circuit, with its 7 km length and challenging sectors like Eau Rouge, offers recovery chances, but starting from the pits adds an extra obstacle.
The alterations made by the teams included:
New V6 engine, turbo, MGU-H and MGU-K for Hamilton, Alonso and Antonelli.
New battery, electronic control unit and exhaust for Hamilton.
Adjustments to the rear suspension of Hamilton’s Ferrari, made without FIA approval.
Modifications to Sainz’s car, done by Williams, also without permission.
FIA regulations and parc fermé
The parc fermé regime is one of the strictest rules in Formula 1. After the start of qualifying sessions, teams are prohibited from making significant changes to the cars, except in exceptional cases and with FIA approval. This regulation, provided in Article 40.9b of the Formula 1 Sporting Code, aims to ensure competitive equality and prevent adjustments that could optimize performance for specific race conditions, such as weather changes. However, the teams of Hamilton, Alonso, Antonelli and Sainz chose to violate these standards, prioritizing the installation of new components for improved reliability and long-term performance.
The FIA found that the part changes exceeded the limits set for the 2025 season. Each driver is entitled to four thermal engines, turbochargers, MGU-H and MGU-K per season, plus two energy storage systems and control electronics. Hamilton, for example, used a fifth engine, turbo, MGU-H and MGU-K, plus a third energy system and electronics, while Alonso and Antonelli also exceeded the engine component limits. These infractions, added to the changes in Hamilton’s Ferrari suspension and Sainz’s car, resulted in the automatic penalty of starting from the pit lane.

Strategy behind the penalties
The choice to make changes in parc fermé, even knowing about the penalties, is not uncommon in Formula 1, especially for drivers facing unfavorable grid positions. In the Belgian GP, Hamilton qualified 16th, Alonso 18th, Antonelli 19th and Sainz 15th, results that put them at a disadvantage on a circuit where starting position is crucial. The teams’ strategy was clear: take advantage of the situation to install new components, which offer greater reliability, and avoid more severe penalties in future races, where they could start in better positions.
Spa-Francorchamps, known for its long layout and high-speed sectors, allows overtaking, but starting from the pits requires a different tactical approach. Teams can adjust the cars for specific conditions, such as rain, which is common in the Ardennes region. The possibility of setting up the cars for high aerodynamic load or rain tires, if the weather changes, was a factor considered by the teams, as pointed out by experts.
Performance in qualifying
The qualifying session on Saturday, July 26, was marked by difficulties for the four penalized drivers. Hamilton, who faced a complicated weekend with Ferrari, had his lap time deleted after an error at the Bus Stop chicane, leaving him in 16th. Antonelli, a rookie at Mercedes, suffered an incident at Stavelot, where he lost control and damaged his car’s floor, resulting in 19th position. Alonso, in turn, did not find pace with Aston Martin, finishing 18th. Sainz, from Williams, also failed to advance beyond 15th place, which motivated the changes to his car.
These results reflect a challenging weekend for top teams, which usually dominate the front rows. McLaren, for example, secured pole with Lando Norris, followed by Oscar Piastri, while Charles Leclerc, Hamilton’s teammate at Ferrari, took third place. The decision to make changes to the cars was, therefore, an attempt to minimize losses in an already unfavorable scenario.
Impact on the starting grid
With the penalties, the Belgian GP starting grid underwent significant changes. Only 16 cars will line up on the track, with Franco Colapinto, from Alpine, and Lance Stroll, from Aston Martin, moving up to positions 15 and 16, respectively. The absence of four drivers from the grid opens space for different strategies, especially for mid-pack teams like Williams and Alpine, which may seek important points.
The main grid positions include:
Lando Norris (McLaren) in pole position.
Oscar Piastri (McLaren) in second.
Charles Leclerc (Ferrari) in third.
Max Verstappen (Red Bull) in fourth.
Alex Albon (Williams) in fifth.
History of penalties at Spa
The Spa-Francorchamps circuit has already been the stage for similar penalties in previous years. The combination of a long layout, which demands a lot from engines, and the possibility of overtaking makes Spa a strategic location for teams to perform component changes. In past seasons, drivers like Max Verstappen and Sebastian Vettel also chose to start from the pits after engine changes, taking advantage of the circuit’s characteristics to recover positions.
The 2025 edition, however, stands out for the number of drivers penalized simultaneously. The decision by four elite teams – Ferrari, Mercedes, Aston Martin and Williams – reflects the pressure for performance in a highly competitive season, where every point can be decisive for the championship.
Weather conditions and strategies
The Belgian Grand Prix is known for its unpredictable weather conditions, with rain often altering team strategies. In 2025, forecasts indicate the possibility of a wet track, which could benefit drivers starting from the pit lane. Starting from the pits allows additional adjustments to the cars, such as choosing slick or intermediate tires, depending on the weather. For Hamilton, Alonso, Antonelli and Sainz, this flexibility could be an asset, especially on a circuit where tire management is crucial.
Rain, if confirmed, could also level the performance differences between cars, offering penalized drivers a chance to advance in the pack. However, sectors like Eau Rouge and Raidillon require precision in wet conditions, increasing the risk of errors.
Team reactions
The teams justified the changes as a technical necessity for the rest of the season. Ferrari, for example, highlighted that the adjustments to Hamilton’s suspension aimed to improve the car’s balance, which faced difficulties in practice sessions. Mercedes, in turn, emphasized the importance of equipping Antonelli with a new engine to ensure his competitiveness as a rookie. Aston Martin and Williams followed the same line, prioritizing reliability for upcoming races.
The decision, although risky, is seen as a long-term investment. With the 2025 Formula 1 calendar including demanding circuits like Hungaroring and Monza after Spa, the teams sought to minimize the risk of future mechanical failures.
Challenges of the pit lane
Starting from the pit lane at Spa-Francorchamps is a complex task. Drivers exit the pits after the race start, which puts them at a disadvantage relative to the pack. Additionally, the pit lane entry and exit at Spa is narrow, requiring care to avoid incidents. However, the long layout and overtaking zones, such as the Kemmel straight, offer opportunities to advance, especially for experienced drivers like Hamilton and Alonso.
For Antonelli, facing his first Formula 1 season, starting from the pits will be a test of adaptation. The young Italian, pointed out as one of the sport’s promises, will need to demonstrate skill to recover positions on a challenging circuit.
Perspective for the race
The 2025 Belgian GP promises to be a test of bold strategies and recovery. Hamilton, Alonso, Antonelli and Sainz, despite the penalty, have competitive cars and enough experience to seek points. McLaren, with Norris and Piastri at the front, is the favorite, but the presence of Verstappen and Leclerc in the front rows guarantees a fierce dispute. The possibility of rain adds an element of unpredictability, which may favor drivers starting from the pits.
The race, scheduled for 3 PM local time, will be a crucial test for the teams, which will need to balance aggressiveness and caution on one of the most iconic circuits in Formula 1.
