Charles Leclerc moved Ferrari to the top of the timing screens on Bahrain Pre-Season Testing 2026 Week 1 Day Two with a 1:34.273 set on the C3 compound early in the morning session, finishing half a second clear of Lando Norris on C2 and with Oliver Bearman third for Haas, but while the headline shows pace the underlying story was limited running for two of the sport’s heavyweights, Mercedes managing just 54 laps across the entire day after Kimi Antonelli’s power unit issue restricted him to three laps and Red Bull’s RB21 completing a single installation lap in the morning due to a hydraulic leak before Isack Hadjar recovered mileage in the afternoon during a session punctuated by three red flags and shaped more by repair work than time attack.
Key Points – Bahrain Pre-Season Testing 2026 Week 1 Day Two
- Leclerc fastest with 1:34.273 on C3
- Norris +0.511 on C2, Bearman third
- Mercedes limited to 54 total laps
- Antonelli completed just 3 laps due to PU issue
- Red Bull morning halted by hydraulic leak
- Three red flags interrupted running
- Norris logged 149 laps, highest individual tally
- C3 accounted for 52% of total mileage
Track Activity – Morning To Nightfall
Leclerc set the early benchmark and it stayed there. The Ferrari’s C3 run arrived before midday heat peaked and no one dislodged it as the session transitioned into longer programmes.
Norris followed with a 1:34.784 on C2 before quietly building the largest lap tally of the day. By the time the floodlights took over, the McLaren had completed 149 tours, cycling compounds and gathering repeatable long-run data without interruption.
The morning was messy.
Red Bull’s RB21 managed a single installation lap before a hydraulic leak forced it back behind the garage doors. Mercedes suffered the heavier blow. Antonelli completed just three laps before a power unit issue required a full change, wiping out the entire morning session.
Interruptions continued. Valtteri Bottas shed part of a mirror on the Cadillac. Pierre Gasly stopped at Turn 1 after Alpine spotted something in the data they did not like. The final red flag came late as Race Control carried out procedural system checks.
By the afternoon, recovery became the objective.
George Russell completed 54 laps exclusively on C3 to place fourth overall. Hadjar salvaged Red Bull’s running with 87 laps and fifth on the timesheet. Bearman logged 130 clean tours for Haas, while Ferrari accumulated 139 laps with Leclerc alone.
Fernando Alonso completed 98 laps for Aston Martin but finished over four seconds off Leclerc’s benchmark, a margin that raises more questions about outright pace than reliability at this stage.
Mileage still tells you who’s comfortable.
Reliability & Early Signals
Two days into the new regulation cycle, stress points are beginning to show.
Mercedes have now lost significant track time across consecutive sessions. Antonelli’s full power unit swap was described as the fastest solution, but it leaves the team behind on setup work compared to rivals who have completed near race distances without interruption. Russell’s afternoon running steadied the programme, yet the lap deficit is visible.
Red Bull’s hydraulic issue was narrower in scope but still instructive. A single-lap morning compresses correlation work into a shorter window. In a year defined by deployment calibration and cooling margins, that matters.
Elsewhere, Alpine stopped proactively after a data spike. Cadillac reached 109 total laps despite its hardware interruption. Ferrari, McLaren and Haas completed heavy programmes without visible disruption.
At this stage, clean days are worth more than headline times.
Tyres & Data Picture
Compound usage mirrored Day One.
C3 accounted for 52% of total mileage with 649 laps. C2 covered 28% at 345 laps. C1 represented 21% with 259 laps. No intermediates were used.
Leclerc’s quickest lap came on C3. Norris’ best effort was set on C2, with the McLaren also recording the fastest C1 time of the day. That cross-compound stability stands out more than the half-second deficit.
Longer runs defined the afternoon. Racing Bulls logged a 22-lap sequence on C1. Cadillac completed 19 laps on C2. Ferrari executed a 19-lap C3 stint that appeared closer to race conditions than time chasing.
With track temperatures ranging between 25°C and 42°C, degradation modelling and energy deployment management shaped the agenda.
Team Reaction
Mercedes were candid about the disruption to their programme.
“We’ve endured another frustrating day here in Bahrain. Kimi lost the entire morning session after we found an issue with the Power Unit; changing the whole unit was quicker than swapping the affected part but unfortunately meant we weren’t back on track with George until one hour into the afternoon running.”
Andrew Shovlin – Trackside Engineering Director, Mercedes
That leaves the team playing catch-up on setup and correlation heading into the final day of the first test.
Williams, by contrast, continued working methodically through energy deployment and setup variation. Matt Harman described it as another positive day exploring “a large part of the envelope of the car,” with temperature behaviour encouraging enough to begin pushing harder as understanding builds.
Haas struck a similarly calm tone after completing 130 laps, while Alpine emphasised precaution over panic following Gasly’s stoppage. Ferrari simply completed its work and left with the benchmark time.
Coffee Corner Take
Day Two wasn’t about Leclerc being quickest.
It was about how thin the margin already feels.
A power unit swap.
A hydraulic leak.
A car stopped because the data looked wrong.
A mirror coming loose.
Small things on their own. Add them up and you start noticing.
Mercedes are chasing time they’ve already lost. “Behind on setup work” is more telling than fourth place in February.
Red Bull recovered their day, but one installation lap in the morning is still one installation lap.
And Aston Martin. Ninety-eight laps is healthy. Four seconds off the headline pace is not flattering, however you dress the fuel loads. They don’t look broken. They just don’t look close.
Ferrari look settled. McLaren look repeatable. Haas look dependable.
The rest are still ironing creases out of machinery that hasn’t yet lived through a race weekend.
Day Three suddenly carries more weight than it did 24 hours ago.
