Second practice at Spa-Francorchamps was supposed to answer the weekend’s most important question: who has race pace over 44 laps of the Ardennes? Then Pierre Gasly’s Alpine met the barriers at Fagnes with 15 minutes remaining, and the question survived the evening intact. What the paddock was left with is a partial dataset — four-lap cameos where twenty-lap rehearsals should be. Yet within those fragments, the contours of Sunday’s 308.052-kilometre (191.415-mile) race are already faintly visible.

The Numbers We Did Get

Strip away the single-lap theatre and the fuel-load runs produce a compact leaderboard of their own — one that mirrors the qualifying simulations with one conspicuous difference.

• Kimi Antonelli — 1m51.511s average (4 laps): short, but metronomic. All four laps were separated by less than three tenths of a second, the signature of a driver and car in total harmony.
• Max Verstappen — 1m51.876s (7 laps): the longest run of anyone before the red flag, and quick enough to split the two Mercedes. Red Bull’s race trim looks entirely credible.
• George Russell — 1m51.980s (3 laps): a step behind his team-mate on long-run pace, just as he was over a single lap — though three laps is barely a sample.
• Isack Hadjar — 1m52.449s (6 laps): a clear margin off Verstappen, on a weekend already compromised by a back-of-the-grid start for exceeding his 2026 power unit allowance.

Mercedes’ Between-Sessions Transformation

The most revealing work of Friday happened behind closed garage doors. Antonelli spent the morning complaining of an edgy, nervous car; Mercedes responded with what insiders described as “massive changes” between sessions, and the afternoon produced a different machine entirely — fastest over one lap, fastest over four. In a title fight defined by fine margins, that capacity to diagnose and rebuild in three hours may prove the season’s decisive weapon.

Russell’s picture is murkier. His morning was compromised by a power issue, fixed for FP2 — yet the deficit persisted, and its geography is telling. The Mercedes deployment quirk first spotted at Silverstone was back at Spa, with both drivers lifting off just before the start/finish line to manage energy. The difference is degree: Russell’s lift on his fastest lap was dramatically bigger than Antonelli’s, costing him roughly half a second in that zone alone. Most of his 1.285-second single-lap deficit accumulated on the straights, pointing to less efficient harvesting rather than a chassis problem. It is the sort of gap that software, not hardware, can close overnight — but it must close.

Verstappen’s Solid, If Not Silent, Friday

Red Bull arrived having parked its flamboyant ‘Macarena’ rear wing after the crashes of Austria and Silverstone, reverting to an older, more conservative specification — and the RB22 looked all the healthier for it. Verstappen’s seven-lap sequence was the day’s most substantial piece of race simulation, and his morning had already delivered top spot in FP1. The one discordant note came over the radio, where the four-time champion branded his gear shifts “unacceptable”. Afterwards, he offered context.

“I’m always very sensitive to these things because I want to work on that and improve it. There was a software update, or downgrade, that took a bit of time for the shifts to learn, and it got a bit better again at the end.”

Ferrari: The Great Unknown

If Mercedes revealed the most on Friday, Ferrari revealed the least. Charles Leclerc was exactly one lap into his long run when the red flag flew; Lewis Hamilton had not properly begun his. The Scuderia’s single-lap pace was respectable rather than spectacular — but this is a team with a rich recent history of underwhelming Fridays blooming into very good Saturdays and Sundays.

Team principal Fred Vasseur, though, let slip the weekend’s most fascinating technical subplot: Ferrari and Mercedes are deploying their electrical energy in almost opposite places.

“Without disclosing any secret, but if you have a look on the race trace, we were 20km/h slower than some of our competitors before Les Combes, but we were 20km/h faster in the last straight line. It’s a trade-off for sure. It’s not that you can do a plus 20 and a plus 20.”

— Fred Vasseur, Ferrari team principal

Translated: Ferrari is spending its battery early, on the climb to Les Combes, and paying for it later in the lap; Mercedes is doing the reverse. Twenty kilometres per hour — roughly 12 mph — in either direction is an enormous swing, and deployment strategies are expected to converge as the weekend matures. Where they converge, and whose baseline is genuinely faster, will decide the pecking order far more than Friday’s timesheets did.

The Honest Caveats

Nobody is pretending the picture is complete. McLaren, whose Lando Norris finished second on the road yet starts Sunday with a 10-place grid penalty for exceeding his power unit component allocation, was first to wave the caution flag in its post-session summary: at a circuit where energy deployment defines performance, “the current pecking order remains far from fixed, and today’s result does not portray the true competitive standing.” Norris himself called the car “still very, very difficult to drive” — even while conceding McLaren looks relatively competitive.

The midfield ledger is equally smudged. The interruptions make it impossible to verify whether Alpine — with Franco Colapinto an eye-catching seventh on single-lap pace — has genuinely rejoined the fight with a Racing Bulls team sitting just one point behind it for fifth in the constructors’ championship. Colapinto believes Alpine has “found a little bit of performance this weekend”, helped by the cooler Ardennes air. Belief, however, is not data.

What Friday ultimately delivered is a set of competing hypotheses: Mercedes’ balance and consistency, Red Bull’s durability, Ferrari’s hidden deployment card, McLaren’s raw-but-restricted speed. The evidence resumes at 13:30 local time on Saturday with final practice — the last chance to turn fragments into answers before qualifying decides who carries the advantage into Sunday’s energy chess match.
