The final week of pre-season testing in Bahrain began under desert skies on Wednesday, February 18, 2026, with all 11 Formula 1 teams returning to the Bahrain International Circuit for the first day of the second test ahead of the season opener in Melbourne. What unfolded was a day of competitive lap times, varying mileage across the grid, technical gremlins for several teams, and continued governance discussions from the sport’s governing body, the Fédération Internationale de l’Automobile (FIA) — all of which provide pivotal talk going into the 2026 campaign.

Russell Leads the Timesheet — Barely
At the top of the leaderboard was George Russell, setting the quickest time of Day 1 with a 1:33.459 lap on the improved afternoon surface. The Mercedes driver edged out Oscar Piastri by just 0.010 seconds — a testament to how tight the running was among the frontrunners.
Third on the combined timesheet was Charles Leclerc for Ferrari — the morning pace setter with a 1:33.739 lap — showing pace early and holding that benchmark until the afternoon charge.
Other notable positions included Lando Norris (McLaren) fourth, Mercedes junior Kimi Antonelli fifth, and Isack Hadjar in the Red Bull sixth fastest.

McLaren followed closely with 124 laps across both drivers.
-
Ferrari delivered solid mileage with 114 laps.
-
Red Bull ran a lighter programme, completing 66 laps with Hadjar staying in the car all day.
-
Aston Martin struggled, completing just 54 laps amid power unit issues.
-
Cadillac had a disrupted day with only 59 laps.
Driver & Team Quotes — Raw Reactions
Many drivers echoed a familiar theme — testing is about gathering data and running programmes, not race pace.
Mercedes
“We’re making steady progress but there’s plenty to analyse and improve before Australia,” Russell said after topping the board. “It’s hard to know the full picture with fuel loads and tyre use varying so much.” — Team radio/press
Mercedes’ benchmark pace, combined with the mileage, suggests momentum, but engineers caution that testing timesheets only tell part of the story.
McLaren
Piastri summed up a productive day for McLaren:
“Overall it’s been productive. We’ve made good progress through our programme, and getting experience in these conditions is really valuable.” — Team statement
Lando Norris, in the team’s other car, noted:
“We’ve worked through set-ups and tyre data — it’s all about preparation here, not headlines.” — Team radio
Ferrari
Leclerc was circumspect:
“The focus isn’t on times. We’re learning; we’ve done good laps and our pace feels promising, but this is still testing.” — Team press release
Hamilton, making consistent runs through the afternoon, added:
“It was a solid day. We got valuable long-run data, which will help our planning.” — Team channel
Red Bull
Hadjar — standing in all day — acknowledged:
“We lost a bit of running in the morning but the afternoon was useful. We’re working through areas and pushing hard.” — Team radio
Aston Martin
A tough day for the team saw Lance Stroll trigger a red flag with a spin, ending his session in the gravel. Chief Officer Mike Krack remarked:
“Despite a lack of running, each lap brings insights. The priority now is rebuilding tomorrow’s programme.” — Team briefing
FIA Commission & Power Unit Committee Statements
Off the track, the FIA’s governance bodies — the F1 Commission and the F1 Power Unit Advisory Committee — issued statements during the day.
According to the announcements:
-
The F1 Commission, chaired by FIA Single-Seater Director Nikolas Tombazis and F1 CEO Stefano Domenicali, agreed on refinements to the 2026 regulations to be passed to the World Motorsport Council for approval.
-
Teams, FIA and FOM collectively committed to reviewing technical elements, including energy management, aerodynamics, overtaking, tyres and mechanical grip, with more data expected across this second test.
-
Positive feedback was received on car behaviour — particularly the reduced weight and improved acceleration — though no immediate major changes were deemed necessary.
-
A proposal to evaluate race start procedures further is underway after constructive discussions.
The Power Unit Committee also progressed a proposal to tighten compression ratio compliance testing, requiring engines to be validated at operating temperatures of 130 °C from August 1, 2026, with an industry vote expected soon.
Incident Highlights & Miscellany
Stroll Red Flag
A mid-afternoon spin from Stroll in the Aston Martin sent the AMR26 into the gravel at Turn 10 — halting the session briefly — highlighting the fine margins drivers face while ironing out setups.
Simulator Race Start Trial
Near the close of play, teams participated in a simulated start procedure trial, involving formation laps and revised light sequences, feeding into the broader safety dialogue as raised by some drivers about the complexity of new 2026 start systems.
Looking Ahead
With three days scheduled in this second Bahrain test, teams will continue to refine setups, collect long-run simulations, and assess their cars under various fuel and temperature windows.
Day 1 showed a tightly packed midfield and highlighted the ongoing puzzle that is pre-season performance analysis — where times mean less than the data behind them. Reliability, tyre degradation, and race-simulation pace will be key threads to watch as the test rolls on toward Friday and ultimately into the Australian Grand Prix opener.
