Formula 1’s 2026 regulations officially hit the track during a five-day shakedown at the Circuit de Barcelona-Catalunya. The test was held behind closed doors and mainly focused on system checks, mileage and initial understanding of the new technical rules.

Lewis Hamilton topped the combined timesheets with a best lap of 1:16.348, set late on the final day. The Ferrari driver beat George Russell’s earlier benchmark of 1:16.445 by just under one tenth of a second. Lando Norris finished third overall with a 1:16.594, placing McLaren within three tenths of the fastest time.

The top five was completed by Charles Leclerc (1:16.653) and Mercedes rookie Kimi Antonelli (1:17.081). Oscar Piastri (1:17.446) and Max Verstappen (1:17.586) followed closely, with eight drivers lapping in the 1:17s during the test. At the other end of the timesheet, Aston Martin and Cadillac drivers recorded lap times above 1:20, reflecting limited running.

Mileage figures provide a clearer picture of team progress. Mercedes completed 502 laps, the highest total of all ten teams. Ferrari followed with 440 laps, while Haas ranked third on 386 laps. Alpine (349 laps) and Racing Bulls (319 laps) also achieved solid mileage across the five days.

McLaren completed 291 laps, while Red Bull logged 303 laps, despite losing time earlier in the week. Audi finished the test with 240 laps, focusing mainly on problem-solving during its first F1 running. Cadillac recorded 164 laps in its debut test, while Aston Martin completed just 65 laps after arriving late and suffering early technical issues.

From a power unit perspective, Mercedes engines dominated the opening test. Mercedes-powered cars completed a total of 1,142 laps, comfortably ahead of Ferrari-powered teams on 990 laps. Red Bull Powertrains reached 622 laps in its first-ever F1 test as an engine manufacturer. Audi (240 laps) and Honda (65 laps) naturally recorded lower totals, as each currently supplies only one team.

On an individual level, George Russell was the busiest driver of the week, completing 265 laps alone. Esteban Ocon followed with 239 laps, while Kimi Antonelli logged 237 laps. Charles Leclerc (235 laps) and Pierre Gasly (231 laps) also exceeded the 230-lap mark.

Lewis Hamilton completed 205 laps, balancing mileage with performance runs. Lando Norris finished on 163 laps, while Max Verstappen completed 145 laps. At the bottom of the list, Lance Stroll managed just 4 laps before Aston Martin suffered a breakdown.

While lap times remain unofficial and largely secondary at this stage, the numbers underline a strong start for Mercedes in terms of reliability and preparation. Other teams prioritised learning and system validation, with performance comparisons expected to become more relevant later in pre-season. Williams was the only team that did not take part in the five-day Barcelona shakedown
