Ahead of today's second session, the air temperature is 30 degrees C, and the track temperature is 43 degrees. It remains bright and sunny.

As a reminder, in terms of updates, McLaren has a new Front Corner, Rear Corner and Diffuser. The front corner scoop and furniture have been revised in conjunction with the front suspension fairings aiming at improved flow conditions, while the rear corner furniture has been revised to achieve an improvement in flow conditioning as well as increased local load. The diffuser geometry has been modified aiming at an improvement of flow conditioning and local load across the speed range.

Red Bull has a new Front Wing and Front Corner. Taking the recently introduced front wing geometry, an option to operate with the tyre temperature turning vane has been added for evaluation, offering a tyre surface temperature measurement as well as more local load with similar flow stability. At the rear, the periphery of the gaitor has been revised to reduce the likelihood of tearing the elastomeric material during running by reducing the strain in the regions of highest deflection when steering lock is applied.

Ferrari has a new Floor Body, Floor Board, Sidepod Inlet/Coke Sidepod and Diffuser. Key development features have focused on increasing floor downforce (on both front and rear parts) whilst also increasing energy levels and flow stability sent towards the back of the car. Benefitting from improved onset flow quality, the diffuser expansion and overall geometry has been further optimized, and returns increased aerodynamic load in an efficient way.

RB has a new Front Wing, Rear Wing, Floor Body and Coke/Engine Cover. The front wing endplate plays an important role in managing the flow around the front tyres. These updates further improve the management of the flow field downstream. Meanwhile, the camber and chord of the rear wing flap elements has been modified to clean up the local flow and allow the wing to generate more load. A combination of developments across a number of key floor components will improve the overall flow management around the floor. This translates into an efficient downforce increase. Working in combination with the updates made to the floor, the changes to the engine cover help manage the flow as it passes around the side of the car and towards the rear.

Audi has a new Front Corner, Front Floor and Mirror stay. The revised front brake duct provides updated cooling characteristics together with associated aerodynamic performance, complementing the latest development steps introduced, while the updated floorboard geometry is intended to improve local flow conditioning and support the overall aerodynamic performance of the floor assembly. Finally, the updated mirror stay geometry complements the revised front corner configuration and supports the overall aerodynamic performance of the car package introduced lately.

Alpine has a new Floor Corner and Rear Wing. The rear floor corner has been redesigned to improve the local flowfield interaction with the rear corner while also increasing local load, while the second and third element flap of the rear wing have been redesigned to improve rear wing flow quality and overall load delivery.

For its home race, Cadillac has new Floor Fences and Cooling Louvres. Th revised geometry of the floor fences improves flow conditioning to the rear of the car and reduces sensitivity to changes in car attitude, whilst retaining overall aerodynamic load. Meanwhile, the sidepod top deck louvres have been updated to increase the power unit cooling capacity, whilst minimising the effect on aerodynamic performance.

Leclerc was quickest earlier, edging out Verstappen by just 0.084s. It was a problematic session for both Williams drivers, while track limits are also going to be an issue as the weekend progresses. Indeed, the opening session saw 79 violations at Turns 1, 3, 4, 9, 11, 12, 15, 19 & 20.

Colapinto has a 10-place grid drop for taking on a fourth Control Electronics, while Bortoleto drops 20 places for taking on an extra Control Electronics and Energy Store. Lindblad is also set to take a 5-place penalty for taking on an extra ICE.

Gasly gets the session underway followed by Lindblad, Verstappen, Lawson and Bearman. In fact, Verstappen left the pits behind Lawson but barged past the kiwi in Turn 1.

Most are on mediums, and while a few opt for hards Colapinto is on softs.

Verstappen (mediums) sets an early benchmark (36.581), as teammate Hadjar complains that he cannot close his visor.

Bortoleto goes second but is demoted when Hamilton (hard) posts a 37.263.

Lawson is third, ahead of Colapinto and Piastri.

Antonelli (medium) goes second but is leapfrogged by him Mercedes teammate (36.788).

Perez, who handed his car over to Colton Herta for FP1, is last out.

"The seat is moving like crazy," reports Antonelli as Hadjar goes third with a 37.012. However, the Frenchman subsequently has his time deleted, as does Antonelli.

No sooner has Norris gone top with a 36.373 than Russell responds with a 36.035. The Mercedes driver is on mediums while the 2025 world champion is on hards.

Hadjar goes third with a 36.411 as Piastri runs wide in Turn 12.

A 35.934 sees Verstappen retake the top spot on the mediums, as Leclerc aborts after coming across a slow Lawson hogging the racing line.

Moments after letting Russell by, the Monegasque speeds up again, and is forced wide by the Mercedes driver. Very odd.

Russell is shown the black and white for forcing another driver off track. The incident will be investigated.

With 40 minutes remaining, Hadjar fits the red-banded rubber, the Red Bull driver and Antonelli having the track to themselves.

But not for long... as Verstappen, Leclerc and Alonso head out on the softs.

Russell posts a 35.793 but Verstappen responds with a 35.480, the Dutchman quickest in S3.

Leclerc, quickest in the final two sectors, goes top with a 35.291, as teammate Hamilton goes fourth, 0.615s down.

Hadjar is very, very unhappy with his car, describing it as "disgusting". "High speed, front deg," he complains.

No further action over that Leclerc/Russell incident.

Despite being quickest in S2, Norris remains 8th, 1.082s off the pace.

Antonelli goes second, 0.042s off Leclerc's pace.

Lawson improves to seventh with a 36.331 as Albon goes 19th.

"The car is a mess, I have no confidence in the rear," complains Sainz.

Replay shows Russell have a major wobble but somehow keeping it all together.

"Bravo Russell," declares Alonso after being cut-up by the Mercedes driver.

While the Cadillac pair have their customary positions at the foot of the timesheets, both Williams drivers are over 2.4s off the pace.

Attention switches to Sunday again, with high fuel and long runs.

"It's a risk and its a reward," says Alan McNish of the crackdown on track limits. "If you look at last year, those penalties through the race were exactly that, so you've got to keep it within the white lines. If there were walls there instead of white lines, then I'm sure everyone would be within it without a problem."

"What is he doing?" asks Ocon of a slow Leclerc ahead on the racing line. "We'll report that," he is told.

Leclerc is on softs, as are Verstappen and Hamilton, while Antonelli and Russell are on mediums. Norris is on hards and Piastri softs.

Albon reports that he is suffering understeer and oversteer.

Antonelli is setting the same pace as Verstappen, though the Italian is on mediums. Hamilton (soft) is slightly slower, just ahead of Russell (medium) but significantly quicker than Leclerc (soft).

"Leclerc, on the soft, has similar limitations to us," Norris is told. "This is what it will be like on Sunday." The Briton, of course, still on hards.

All this time drivers continue to have their times deleted for track limits violations, which doesn't bode well for qualifying or Sunday.

"I don't think our lap times at the moment are representative of our total pace," says Zak Brown. "Everyone is struggling, sliding around. Everyone is struggling to keep it on the black stuff at the moment."

Hamilton makes a late switch to the hards and immediately makes a move on Ocon.

Norris switches to softs and Piastri to hards. Both have their times deleted, as Lawson, Sainz and Colapinto.

The session ends. Leclerc is quickest, ahead of Antonelli, Verstappen, Hamilton, Russell, Lawson, Norris, Piastri, Hadjar and Bearman.

Bortoleto is eleventh, ahead of Gasly, Lindblad, Ocon, Colapinto, Alonso, Stroll, Hulkenberg, Bottas, Sainz, Perez and Albon.

As in FP1 it was another track limits fest, however it would appear that much of this is down to the fact that the tyres have taken so much punishment in S1 that by S2 and S3 they are done.

Which, as Zak Brown admits, is going to continue to be an issue.
