Ferrari introduces Monza engine upgrade but straight-line gap to Mercedes remains
Ferrari brought its second engine upgrade of the season to its home race at Monza, with Lewis Hamilton describing it as an improvement. However, Hamilton said Ferrari still appeared to be behind Mercedes on top speed and on the straights after Friday practice.
Ferrari ran its second engine upgrade of the 2025 Formula 1 season at the Italian Grand Prix, introducing it at its home event at Monza under the ADUO allowance. The team started Friday strongly, with Charles Leclerc leading a Ferrari 1-2 in first practice.
In second practice, Mercedes responded as George Russell set the fastest time. Lewis Hamilton said Ferrari's new engine was an improvement, but he remained concerned that Mercedes still held an advantage in top speed, which he indicated would be important around Monza.
The assessment from Friday running was therefore mixed for Ferrari: the upgrade showed positive signs, but the car's straight-line performance relative to Mercedes was still viewed as a key limitation heading into the rest of the weekend.
