Leclerc Tops Austin Practice as Ferrari's New Upgrade Faces Its Sunday Test

Charles Leclerc set the pace in practice for the United States Grand Prix at the Circuit of the Americas on Friday, giving Ferrari an encouraging first reading on the upgrade they have brought to Austin. With six rounds left and Mercedes 134 points clear in the constructors’ standings, the title is not in play. What matters is whether this weekend marks a genuine step back towards winning races, or whether Ferrari are about to discover that Friday pace means little.

What a practice timesheet hides

Practice times are the most public numbers in Formula 1 and the least reliable. Teams do not declare fuel loads, engine modes or run plans, and the difference between a car carrying a handful of laps’ worth of fuel and one loaded for a long run is worth far more than the margins that separate the front of the field. A headline lap can come from a single low-fuel push at the end of a session, when the track has rubbered in and grip is at its highest.

Upgrade weekends muddy the picture further. When a team brings new parts, much of its practice running goes on correlation work, comparing what the car does on track with what the wind tunnel and simulations promised. That work is unglamorous, and it often matters more to the engineers than where the car sits on the timesheet. A team can be delighted with a session in which it finished seventh, or worried after one in which it finished first.

Leclerc’s own profile adds another layer. He has long been one of the outstanding single-lap drivers of his generation, and Ferrari have rarely lacked raw speed over one lap in recent seasons. Their recurring weakness has been converting that speed into race pace, particularly in managing tyre temperatures over a stint. A fast Friday from Leclerc confirms that the car can be quick when everything is switched on. It does not, by itself, confirm that the car looks after its tyres any better than it did a fortnight ago.

That is why the paddock pays closer attention to long-run averages than to the top line, even though outsiders can read those only imperfectly, without knowing fuel loads or compounds.

Seventeen rounds of evidence

The season’s numbers frame what a Ferrari victory would represent. Mercedes have won 11 of the 17 Grands Prix so far, eight with Andrea Kimi Antonelli and three with George Russell. Ferrari have won twice, once each with Lewis Hamilton and Leclerc. McLaren and Red Bull have two wins apiece.

Yet Ferrari sit second in the constructors’ championship on 444 points, 105 clear of McLaren and 112 ahead of Red Bull. That gap says something specific about how Ferrari have scored. Hamilton has 229 points and Leclerc 215, the most evenly matched line-up among the leading teams. Ferrari’s position rests on two drivers who finish in the points with near-metronomic regularity, rather than on a car that regularly beats the Mercedes.

That is a respectable season, but it is not a winning one. Being the second-best team on aggregate while winning only two of 17 races suggests a car that is often close enough to lead the chasing pack and rarely fast enough to beat the leaders on merit. Any upgrade that closes that last gap would change Ferrari’s season far more than its points total suggests.

Singapore was the better clue

If there is evidence that Ferrari arrived in Austin already close, it came at Marina Bay two weeks ago. Leclerc started second and finished second, behind Max Verstappen, who converted pole into victory for Red Bull. Antonelli finished third from fourth on the grid, so on that evening Leclerc beat the championship leader in a straight fight.

The weekend was not a clean bill of health, though. Hamilton qualified third and finished sixth, losing ground to Antonelli and both McLarens. Russell, meanwhile, recovered from 19th on the grid to ninth, which suggests Mercedes’ underlying race pace was stronger than the result implied. Ferrari had one car in the fight and one drifting backwards, and uneven weekends of that kind have kept them from winning more often.

Austin asks different questions of a car. Singapore is a slow, stop-start street circuit that rewards traction and low-speed downforce. The Circuit of the Americas opens with a sequence of fast, flowing esses through the first sector, where aerodynamic stability and balance across rapid changes of direction matter most. The surface is notoriously bumpy, which punishes cars run low and stiff, and the long, loaded corners place heavy demands on the front tyres. If Ferrari’s new package has improved high-speed performance, this is the right circuit to show it, and the wrong one on which to hide a weakness.

Recent history offers both encouragement and caution. In 2024, Leclerc won this race at the head of a Ferrari one-two, so the track has suited the Scuderia before. The same season delivered a warning. Ferrari’s major upgrade at that year’s Spanish Grand Prix looked promising on paper but introduced bouncing in high-speed corners, and the team spent weeks working out what had gone wrong and partially rolling the changes back. A package can look quick in a qualifying simulation and reveal its flaws only under race loads, on worn tyres, in specific corners. Under the cost cap, teams can no longer afford to brute-force their way out of a misstep with a stream of replacement parts.

The second place Ferrari can still win

Leclerc trails Antonelli by 125 points, which leaves the drivers’ title out of reach in any practical sense, with only 150 points available from the remaining Grands Prix. Hamilton, 111 behind, is in the same position. What remains open is the fight behind Antonelli, and it is unusually tight.

Position	Driver	Team	Points	Gap to 2nd
2	George Russell	Mercedes	238	—
3	Lewis Hamilton	Ferrari	229	9
4	Max Verstappen	Red Bull	221	17
5	Charles Leclerc	Ferrari	215	23

Four drivers are covered by 23 points, less than the value of a single victory. A Ferrari win in Austin, particularly with the second car close behind, could reshuffle that order in one afternoon. Hamilton finishing as runner-up in his second season at Maranello would be a meaningful marker. So would Leclerc, who starts the weekend fifth, overhauling all three drivers ahead of him over the closing six races.

The constructors’ fight carries a more tangible reward. Second place is worth considerably more in prize money than third, and a 105-point cushion over McLaren is comfortable but not unassailable with six rounds to run. An upgrade that makes Ferrari consistently faster would protect that position as much as it would chase wins.

There is a longer game too. Because the 2026 regulations carry into next season, everything Ferrari learn from this package feeds directly into their 2027 car. A late-season upgrade that correlates well is worth more than a few extra points. It tells the engineers their tools are pointing in the right direction, which is exactly what a team chasing a dominant Mercedes needs to know before the winter.

What Ferrari must prove over 56 laps

The fair reading of Leclerc’s practice pace is that it makes Ferrari credible contenders for victory in Austin, not that it has overturned the order. Mercedes have won too often this year, and recovered from too many awkward weekends, to be dismissed on the strength of one session. Russell’s charge through the field in Singapore was evidence of a car with pace to spare.

The real measure will come over 56 laps. If Leclerc can hold his pace through the stints, keep the front tyres alive through the first sector and have Hamilton running alongside him rather than fading as he did in Singapore, Ferrari will have shown something new. If the advantage melts once the fuel goes in, this will be another Friday the Scuderia read too much into.

My judgement is that the progress is real but narrower than the timesheet suggests. Mercedes should still start Sunday as favourites, but Ferrari now look capable of adding at least one more win before the season ends, and Austin is as good a place as any for it to come.
