2025 F1 Bahrain Testing: Key Moments, Rookie Debuts, and Aerodynamic Insights

The 2025 Formula 1 season officially commenced with three days of pre-season testing at the Bahrain International Circuit, offering fans their first glimpse of the new generation of F1 cars developed under the latest regulations.

Day 1: Hamilton’s Ferrari Debut and Power Outage

Lewis Hamilton took to the track in the SF-25 for his first proper outing after limited private tests. The seven-time world champion described his experience as a process of 'bonding' with the car. The day was marked by an unexpected power outage, which halted testing for over an hour. Mechanics worked under torchlight before power was restored, and the session was extended.

Day 2: Rain, Flow-Vis, and Sainz’s Speed

Day two saw intermittent rain, with Esteban Ocon being the only driver to venture out on intermediate tires. Carlos Sainz set the fastest lap of the test with a time of 1:29.348, narrowly edging out Hamilton. Aerodynamic analysis tools like flow-vis paint and aero rakes were prominently featured, providing valuable data for teams to refine their designs.

Day 3: Red Flags and Illness

The final day was marred by bizarre incidents, including a red flag caused by a shattered glass pane from the gantry and Oliver Bearman’s Haas losing part of its engine cover. Illness struck the Aston Martin drivers, limiting their running. George Russell topped the timesheets with a lap of 1:29.545, while Sainz remained the overall fastest across the three days.

Rookie Spotlight

Six rookies made their debut during the test, including Gabriel Bortoleto (Sauber), Jack Doohan (Alpine), Andrea Kimi Antonelli (Mercedes), Isack Hadjar (Racing Bulls), Oliver Bearman (Haas), and Liam Lawson (Red Bull). Their performances were closely watched as they adapted to the demands of F1 racing.
