Las Vegas promised to be an atypical monitor able to shaking issues up, and the primary day of follow on the U.S. circuit delivered a lot to debate. As anticipated, the low grip ranges and really low temperatures—reaching simply 13°C on the asphalt throughout FP2—considerably impacted each pure lap efficiency and tire administration over longer runs.
Tires will undoubtedly be the first focus all through the weekend. Greater than the vehicles’ technical traits, the important thing issue seems to be how groups exploit the tires and the way a lot grip they will generate.
Alongside monitor evolution, groups pursued various packages. Purple Bull and Ferrari adjusted their setups to progressively scale back drag from FP1 to FP2, aligning with benchmarks from rivals. In the meantime, McLaren diversified throughout the group: Lando Norris opted for a extra loaded entrance wing, whereas Oscar Piastri selected a much less loaded configuration with a trimmed higher flap for Las Vegas.
Mercedes shines on Friday, McLaren within the center
Mercedes usually excels on Fridays however struggles to take care of the sting because the weekend progresses, with rivals enhancing whereas the W15 stagnates. George Russell acknowledges this state of affairs might repeat tomorrow, notably on account of gasoline masses and engine mappings, as Mercedes tends to push tougher on Fridays. However, each Russell and Lewis Hamilton expressed confidence.
Their W15 felt aggressive and carried out effectively beneath the day’s situations, particularly in sluggish sections such because the 7/8/9 sequence and the ultimate chicane, the place it was very sharp on nook entry. This power in sluggish corners has been a season-long development, because the W15 struggles extra in flowing sequences.
The actual distinction lies in tire administration. All through the season, the Brackley automobile has fared higher in cooler situations, shedding grip extra shortly in hotter climates. In Las Vegas, the drivers discovered the automobile difficult to deal with on account of low grip, nevertheless it was general much less nervous than different vehicles—an element that has usually penalized Russell and Hamilton this season.
Nonetheless, Mercedes lacks high pace, falling behind different high groups besides Purple Bull, which loses six-tenths as a result of absence of a real low-downforce package deal. On the Strip, Mercedes trails McLaren by about 3–4 km/h, corresponding to Ferrari when neither Carlos Sainz nor Charles Leclerc advantages from slipstreams. The hole grows to 9 km/h earlier than the braking zone of Flip 4 in comparison with the McLaren MCL38.
McLaren’s automobile, as confirmed by its drivers, is aggressive in qualifying runs, excelling at bringing the tires into the suitable window and capitalizing on high speeds on straights. Nonetheless, McLaren struggled in particular corners, corresponding to Flip 1 and the 7/8/9 sequence, the place Norris lacked the aggression seen from the Mercedes drivers. The group is extra involved about graining throughout lengthy runs—an issue all groups confronted on account of low temperatures—however Norris was notably shocked by the automobile’s tempo with larger gasoline masses.
Oscar Piastri’s future was extra convincing, although McLaren began their stint aggressively, not like rivals who started with larger lap instances to protect the tires. This strategy will seemingly be reviewed post-FP2 to deal with graining points beforehand seen at tracks like Monza.
Ferrari works on comfortable tire efficiency
Ferrari continues to grapple with tire temperatures, a recurring problem this season. The Las Vegas format fits the SF-24 with its lengthy straights and sharp corners that don’t overly stress the entrance tires. Nonetheless, as anticipated, bringing the tires into the suitable window has been difficult.
This challenge has plagued Ferrari in different races, notably when making an attempt to maximise comfortable tires for qualifying. Ferrari struggled extra on the comfortable compound than on the medium, prompting the group to check completely different methods, corresponding to including an additional lap after the outlap to heat the tires additional—contrasting with McLaren and Mercedes.
The circuit’s low aerodynamic load in corners complicates extracting clear laps. Leclerc needed to abort a number of laps, contemplating a brand new strategy for utilizing comfortable tires, whereas Sainz struggled to string collectively an ideal lap, shedding time in Turns 1, 8, and 12 whereas engaged on brake launch to enhance cornering pace.
Flip 1 stays a crucial focus for Ferrari, because it challenges the SF-24’s means to take care of rotation mid-corner with out shedding rear traction on exit. Sainz tried excessive entry speeds however couldn’t maintain the tempo by subsequent sections, shedding tenths to Mercedes and McLaren.
General, the SF-24 performs effectively on straights, aided by a lower-downforce wing setup in FP2 (although Sainz’s Strip reference benefited from a robust slipstream). Nonetheless, Ferrari should enhance grip to seek out rhythm in corners and braking zones, notably with the comfortable tires. Whereas the drivers really feel extra optimistic about race tempo—regardless of graining and degradation points shared with rivals—single-lap efficiency stays a better limitation.
