Ferrari brings engine upgrade to Monza as Hamilton targets home breakthrough

Ferrari has brought an upgraded engine to the Italian Grand Prix as it attempts to improve its straight-line performance at Monza. BBC Sport reported that the change is the second of the two upgrades Ferrari is permitted to introduce this year, with Lewis Hamilton describing it as progress while cautioning that it will not eliminate the team's entire deficit.

Watch the highlights:

The development is especially significant at Monza, where long straights make power and energy deployment central to lap time. According to the BBC's Formula 1 correspondent Andrew Benson, Ferrari has generally been strongest through corners this season but has lost ground on the straights. Hamilton said the deficit was about four-tenths of a second per lap at the previous race.

Hamilton nevertheless believes Ferrari has the ability to win if the team executes cleanly throughout the weekend. A victory would be his first at Monza as a Ferrari driver, adding further weight to the team's home event. The seven-time world champion and team-mate Charles Leclerc have each won one race this season.

The championship picture gives Ferrari another potential opening. Mercedes driver Kimi Antonelli, the current points leader, is set to take a grid penalty after exceeding his permitted allocation of engine components. Reliability issues earlier in the season had made an additional engine necessary, and Mercedes selected Monza as the most suitable venue because a fresh power unit can be valuable on its straight-heavy layout and overtaking is possible.

Hamilton is 59 points behind Antonelli, although he expects the Mercedes driver to recover positions from the rear because of the performance gap between the leading teams and the rest of the field. Antonelli also said he expects Monza to offer a reasonable chance to move through the pack, while acknowledging that Ferrari, McLaren and Red Bull could all be competitive.

Energy management is likely to be another defining factor. The long full-throttle sections provide fewer opportunities than usual to recover battery power, which could cause cars to run without electrical assistance for portions of the straights. Slipstreaming may therefore play an important role in both qualifying and the race, leaving Ferrari's upgrade, tactical execution and Hamilton's ability to harness home support as closely watched elements of the weekend.
