McLaren MCL39 leads with superior entrance grip, Ferrari SF25 loses in first sector


We decide up proper the place we left off. Friday’s free observe in Saudi Arabia as soon as once more painted the identical image seen in latest occasions of this early season, with McLaren main the way in which and able to intimidate its rivals. A now customary papaya one-two, however one which highlights a number of attention-grabbing factors, beginning with the rear wing alternative.

In Jeddah, the Woking group confirmed up with a lower-downforce rear wing in comparison with earlier Grands Prix. It’s not solely new, as this setup had already been examined throughout pre-season testing in Bahrain and in FP1 in Australia, though in each circumstances they reverted to a medium-downforce configuration.

On a circuit like Jeddah, it’s important to strike the correct stability between the downforce wanted to be aggressive within the first sector and high speeds to take full benefit of the lengthy straights within the second and third sectors. The grip supplied by Jeddah’s asphalt—among the many greatest on the calendar—allowed groups to go for decrease rear downforce, as additionally seen in Suzuka.

This context helps clarify why McLaren adopted the trail already taken by different groups, decreasing rear downforce looking for higher straight-line efficiency. Whereas it’s nonetheless unclear how far more McLaren has up its sleeve by way of engine maps, a part of the hole continues to be seen, particularly in comparison with Ferrari and Crimson Bull.

Nonetheless, one necessary issue have to be thought of: as confirmed by Helmut Marko, Crimson Bull ran barely extra aggressive engine settings in Saudi Arabia than common, which suggests the RB21’s efficiency on the straights is already near what we are able to anticipate in qualifying.

To provide a benchmark, on the 2 straights of the second and third sectors, the MCL39 has a pace deficit to Crimson Bull of between 5 and seven km/h. In comparison with Ferrari—which diminished its DRS flap—the hole narrows to round 4 km/h. It’s price noting that in FP2, Charles Leclerc additionally eliminated the beam wing, switching to a model with a single ingredient, whereas retaining the trimmed DRS flap.

So if McLaren is dropping time on the straights, it’s truthful to ask the place it’s making the distinction and the way it managed to complete the lap practically three tenths forward. The key lies within the first sector. Norris, working on Friday with out upgrades, was very aggressive and efficient into Flip 1, carrying plenty of pace into Flip 2 due to late braking.

The important thing issue is how Norris manages to keep up such excessive entry pace with out compromising the transition into Flip 2. That’s the place he builds a part of his benefit—even over his teammate, who was suggested to attempt a extra aggressive method into Flip 1 by braking later.

Norris’s efficiency on this section additionally highlights one other issue: the superb work accomplished by McLaren engineers to scale back mid-corner understeer in slower sections. This enchancment has helped mitigate one of many automobile’s former weaknesses and allowed it to attain a greater stability between high-speed and low-speed areas—now one of many MCL39’s greatest qualities.

On this part, Crimson Bull, Ferrari, and Mercedes all lose a number of tenths, a niche that widens over the remainder of the lap. It’s price noting that Charles Leclerc set his greatest time on his third try, having aborted two laps as a consequence of site visitors. But even on contemporary tires, he struggled in that sector. Additionally, Lando Norris’s time got here on a used set, which isn’t shocking since Jeddah has all the time been a low-degradation monitor.

Trying additional again, Oscar Piastri made up time later within the first sector, particularly in Flip 4, the place he was far more aggressive each on entry and exit, with much less throttle modulation. Curiously, Norris had matched his teammate within the first run, suggesting that if he had nailed the whole lot, the hole might have been even larger.

Total, Flip 4 is a robust level for the MCL39, particularly mid-corner, the place understeer can turn out to be essential. That is mirrored in the truth that even with a less-than-perfect exit, Norris nonetheless gained floor on Ferrari and Crimson Bull. A major a part of McLaren’s benefit is constructed between the primary chicane and Flip 4.

Issues shift within the following sequence of corners—7, 8, 9, and 10—the place Crimson Bull catches up, which isn’t any shock. In these high-downforce corners, which require robust stability and aerodynamic help, the automobiles from Milton Keynes, with their stiff setup, have all the time excelled. What’s shocking is the competitiveness of the SF-25, the quickest of the highest groups in Flip 9.

Within the season’s opening rounds, Ferrari already confirmed enchancment in quicker sections, though each Oscar Piastri and Lando Norris have been additionally lifting barely in that nook. Nonetheless, seeing Ferrari so aggressive there’s actually a optimistic signal.

McLaren regains floor in areas like Flip 4, the place entry is essential and adopted by fast route adjustments, as within the quick chicanes of Turns 16 and 17, the place it positive aspects 7 km/h over the competitors, and in Turns 22 and 23, the place the delta is smaller however nonetheless current.

What’s sure is that, as seen elsewhere, McLaren confirmed itself as the highest group. As anticipated, it makes the distinction in additional technical sections, the place front-end grip and general stability matter most, whereas nonetheless trailing on the straights. Ferrari—significantly with Charles Leclerc—appears to have recognized the route to pursue for the remainder of the weekend.

For Crimson Bull, this was their greatest Friday of the season to this point—an necessary basis, since with an already strong setup, they’ll now concentrate on refining numerous features slightly than overhauling the automobile. Mercedes, then again, stays a query mark: it was extra aggressive in FP1 than in FP2, the place—as a consequence of site visitors and problem activating the delicate tires in cooler monitor situations, particularly for Antonelli—it couldn’t discover the correct formulation to maximise the W16.
