Bahrain played host to the first official pre-season test for the 2026 Formula 1 campaign this week, offering an initial look at the impact of sweeping regulation changes. While Mercedes’ Andrea Kimi Antonelli set the fastest lap time of 1m33.669s on Friday, the focus extended beyond outright pace to encompass reliability and mileage accumulation, with several key narratives emerging from the three-day event.
Antonelli’s benchmark time was 0.249s quicker than teammate George Russell, who recorded the second-fastest lap. However, the Italian teenager completed the fewest laps of any driver – 94 – due to technical issues plaguing the W17. This contrasted sharply with seven drivers who surpassed the 200-lap milestone: Charles Leclerc, Oscar Piastri, Carlos Sainz, Alex Albon, Lando Norris, Lewis Hamilton, and Oliver Bearman, highlighting the importance of endurance in pre-season testing.
McLaren and Williams led the way in terms of overall mileage, both completing 2,284km. Williams’ strong showing is particularly noteworthy, as the team was absent from the earlier Barcelona shakedown. Ferrari followed closely behind with 2,279km, while Mercedes, despite its impressive pace, completed only 1,526km – the second-fewest of all teams – hampered by a power unit problem that limited Antonelli’s running on the second day of the test.
The power unit manufacturers as well presented a varied picture. Mercedes-powered teams collectively amassed over 13,000km, benefiting from the engine’s popularity on the grid with four teams utilizing it. Ferrari also performed strongly, with each team averaging over 2,000km. Audi, in its debut season, exceeded Red Bull’s mileage, while Honda, powering Aston Martin, lagged behind, completing the least amount of mileage among the five manufacturers.
Amidst the on-track activity, Red Bull Racing’s Max Verstappen, who opted not to drive on Thursday, accused Mercedes team principal Toto Wolff of employing “diversion tactics.” This followed Wolff’s comments downplaying the significance of a potential engine advantage stemming from a compression ratio trick, a claim Verstappen dismissed, suggesting the performance gain was far greater than Wolff indicated. Verstappen, who recently confirmed he will remain with Red Bull for the 2026 season after months of speculation linking him to Mercedes, stated, “You definitely have to add a zero to that! And maybe even more.”
Several red flag incidents interrupted testing, including issues with Alpine’s Colapinto and Audi’s Hülkenberg on Wednesday, and further disruptions involving Cadillac and Alpine on Thursday. A cooling issue halted Cadillac’s Bottas on Friday, and Ferrari’s Hamilton experienced a fuel-related issue towards the end of the session. The FIA also initiated several test stoppages throughout the week.
The Bahrain test concluded with several teams facing challenges, particularly regarding reliability. Mercedes’ pace was tempered by technical difficulties, Aston Martin’s running was limited, and Honda’s power unit appeared to be lagging behind its competitors. The next scheduled event is the opening race of the season in Bahrain on February 21st, where the true competitive order will initiate to emerge.
