Ferrari has deliberately parked its biggest technical push of the year until the cars roll into the Autodromo Nazionale on 4 September, and the timing is not an accident. Monza is the lowest-downforce, most power-sensitive circuit on the calendar, and it is Ferrari’s home.

The upgrade, badged ADUO 2 inside the team, is projected to add around 15 horsepower, roughly double the 7hp step Ferrari brought to Austria earlier in the season. Italian technical outlet AutoRacer puts the potential lap-time gain at around two tenths of a second, a figure that would matter more at Monza than almost anywhere else the season visits.

The turbocharger Ferrari has been holding back

The centre of the package is a new turbocharger. Ferrari is going back on its original 2026 concept of a smaller turbo and moving to a redesigned unit with different blade angles, a revised blade count and materials aimed at handling higher combustion temperatures.

Combined with the earlier step, the two ADUO upgrades are targeting a total gain in the region of 30 horsepower over the original specification. That figure exists only because the FIA’s power-unit ranking mechanism gives the team room for the work. Ferrari’s engine is rated around 4 per cent down on Red Bull, and that gap is what unlocks the two upgrade slots inside the season’s cost-controlled framework.

A floor evolution built on the Barcelona package is expected earlier, at the Dutch Grand Prix on 23 August, before the engine step arrives at Monza a fortnight later.

Hamilton banks on Ferrari’s second-half push

Hamilton went into the mid-season break sounding almost patient. Speaking to media at the Hungarian Grand Prix, he framed the first half as a job done in difficult circumstances, and the second half as the phase Ferrari has been building towards.

“It has been an amazing first half given I think we’ve been probably, like, three, four tenths down on the straights, in terms of power for the first half of the season,” he told reporters in Hungary.

“I know the guys are pushing hard to bring upgrades, and we’ve got more to come in the second half.”

He was blunter about his own record.

“I think the second half will be stronger. Usually, the second half is a stronger period for me.”

The numbers behind that optimism are unforgiving. Kimi Antonelli leads the drivers’ championship on 219 points after Mercedes’ 19-year-old Italian took a podium in Hungary. Hamilton is second on 169, with George Russell third on 160 and Charles Leclerc fourth on 138, according to the standings after round 11.

Eleven rounds remain, and with sprint weekends included there are still hundreds of points on the board. A 50-point deficit is not final in August, but it is the kind of gap that only closes with a car that stops giving away time in a straight line.

Ferrari’s answer to that problem is on its way. The Dutch Grand Prix is at Zandvoort on the weekend of 21 to 23 August. Two weeks later the paddock moves to Monza, where the Italian Grand Prix runs from 4 to 6 September, and Ferrari will find out whether the turbo it has been holding back is worth what it says on the dyno.
