McLaren Struggles in Bahrain Despite Topping Timesheets

McLaren, the reigning powerhouse of the Formula 1 circuit, found themselves at the top of the timesheets in both Friday practice sessions ahead of the Bahrain Grand Prix. However, Lando Norris, the championship leader, expressed his disappointment with the performance of his Papaya machinery.

The Impact of Changing Conditions on Performance

The Bahrain International Circuit, hosting both pre-season testing and the fourth round of the 2025 Formula 1 season, presents a stark contrast in conditions. Friday’s FP1 saw temperatures soaring, making it challenging for drivers.

During pre-season testing, the circuit was unusually cool, with air temperatures barely surpassing 20°C and track temperatures struggling to reach 19°C. In stark contrast, this weekend’s race temperatures were significantly higher, with FP1 seeing track temperatures close to 50°C. Even as the sun set, the track temperature still reached 38°C, making it a challenging weekend for the drivers.

The Role of Temperature in Car Performance

Temperature plays a crucial role in car performance, particularly affecting the tyres. In hotter environments, rubber gets softer and exhibits more grip faster. However, insufficient cooling can cause the rubber to swing out of its operating window, as experienced by Norris.

This rear-limited circuit is more abrasive compared to Japan last weekend. Despite using the same tyre compounds, we’ll witness a different race unfold this Sunday due to these factors.

Pirelli’s Take on the Conditions

Simone Berra, Pirelli’s chief engineer, commented on the high thermal degradation on the tyres, stating that it could lead to a two-stop race with all three compounds potentially playing their part.

Norris’ Perspective on the Challenging Conditions

Norris acknowledged the limitations of these conditions, expressing his concern about looking after the rear tyres in the best possible way. He emphasized that the team would have to discard most of their pre-season testing data and start anew due to the significant difference in conditions.

McLaren’s Performance Delta

Despite the challenges, both McLaren drivers showed strong performance today, with Norris commanding FP1 and Piastri leading FP2. However, the almost three-second difference between their best times highlights the significant performance delta compared to Red Bull, which appears to be struggling in this area.

Despite the pessimism, both McLaren drivers showed strong performance today. Norris commanded FP1 with a time of 1:33.204, and Piastri led FP2 with a 1:30.505. Note the almost three-second difference. This proves ‘s broad operating window and superior tyre temperature control, especially compared to Red Bull.
