The Monegasque driver consistently improved his benchmark throughout the day, ultimately nine tenths ahead of McLaren's Lando Norris. Verstappen claimed third for Red Bull, leaving Mercedes to troubleshoot after a power unit change following a red-flag incident.

Alpine's Pierre Gasly led the midfield battle with a 1m33.421s, just 0.066s ahead of Haas' Oliver Bearman. Rookie Arvid Lindblad impressed with a remarkable 165-lap day for Racing Bulls, while Kimi Antonelli's reference time from the previous day remained unbeaten by others. Mercedes endured a difficult session with both reliability concerns and limited running time.

Aston Martin's testing ended abruptly after just six laps due to an engine parts shortage stemming from Fernando Alonso's battery issue. Cadillac continued their pattern of late starts while Valtteri Bottas set their best time at 1m35.290s. The test concluded with teams heading to the season opener with Leclerc's Ferrari showing clear pace advantage.
