Ferrari’s expected Baku engine penalty for Charles Leclerc is a strategic choice born from a crash, a recovery and a longer-term power-unit plan. The key point is that the ADUO2 engine from Monza was not destroyed. It passed subsequent inspections, but Ferrari is still expected to fit a fresh version for qualifying and the race—an additional unit that would bring a major grid penalty.

Why Leclerc is expected to start at the back
Leclerc’s expected penalty is not punishment for the Monza accident itself. It would result from Ferrari introducing another fresh ADUO2-specification 067/6 power unit beyond his permitted seasonal allocation. Reports indicate that the new unit would be homologated for Baku qualifying and the race, with the resulting engine-related penalty expected to put him at or near the rear of the grid.

That distinction matters: Ferrari has recovered the Monza unit, but wants a fresh upgraded engine available as its principal race unit for the closing phase of the season.

What happened to the Monza engine
Leclerc crashed heavily at the exit of Parabolica during the Italian Grand Prix. The impact led Ferrari to remove the newly introduced ADUO2 power unit and withhold it from the subsequent Spanish Grand Prix while engineers investigated the risk of internal damage.

The eventual verdict was encouraging. Reporting based on Ferrari’s checks said the unit’s sensors showed no significant anomalies, while X-ray examination also cleared it for recovery. The engine therefore was not considered terminally damaged.

Ferrari nonetheless acted conservatively. A power unit can appear sound after inspection without being the ideal choice for the high-load demands of race use, particularly when the team has a fresh engine available. That is why the recovered unit is expected to return as a rotation engine rather than be discarded.

Why Ferrari may run the salvaged engine in Thursday practice
The reported plan is to use the recovered ADUO2 engine during Baku practice, then install the new unit for qualifying and the race. This gives Ferrari a chance to put the recovered engine back into service while limiting its role and preserving the fresh unit for the sessions that determine points.

Baku’s altered timetable makes Thursday the opening practice day. The Azerbaijan Grand Prix has been moved forward by a day: practice is Thursday, qualifying is Friday, and the race takes place on Saturday, September 26. Formula 1 and the FIA made the change following a request from the promoter and relevant government stakeholders to avoid Azerbaijan’s Remembrance Day on September 27.

Why Baku is Ferrari’s preferred place to take the penalty
Ferrari team principal Frédéric Vasseur has indicated that Baku could suit the team as a venue for an engine penalty. The calculation is straightforward: the team would rather absorb the grid cost at a circuit where it believes recovery remains possible, then have a fresh upgraded power unit available for later rounds.

It is still a costly choice. Leclerc has been particularly strong over one lap in Baku, taking four consecutive pole positions before 2025, yet he has not converted that run of poles into a victory there. Starting from the back instead of competing for the front of the grid gives up an important historical strength.
16
The decision is therefore not a claim that Baku makes a back-row start easy. It is a trade-off: sacrifice one weekend’s starting position to strengthen Ferrari’s engine pool for the remainder of the championship.
How much faster is the ADUO2 engine?
Ferrari introduced its second ADUO-permitted upgrade at Monza. Contemporary reporting estimated the revised 067/6 engine and updated Shell fuel package at roughly 15 horsepower over the earlier specification.
17
That is a useful improvement, especially at circuits where power matters, but it is not a complete reset of Ferrari’s competitiveness. Assessments after Monza said the ADUO2 upgrade had not eliminated Ferrari’s remaining power shortfall to Mercedes.

For Leclerc, the practical benefit of taking the Baku penalty is not merely a single-race gain. It is access to a fresh upgraded unit for the later part of the season, rather than relying entirely on an older engine or a recovered one.
What it could mean for Hamilton and Ferrari’s constructors’ position
Ferrari has also been reported to be considering a similar extra-engine strategy for Lewis Hamilton, with the possibility of separating the drivers’ penalties between Baku and Austin. That remains a reported option rather than a confirmed decision.
11
Splitting penalties would avoid compromising both Ferrari cars at the same round, but it could also reduce the team’s scoring potential across two weekends. That matters because Ferrari’s immediate constructors’ concern is protecting second place, not mounting a direct challenge for first: after round 14, Mercedes led on 503 points, Ferrari had 358 and McLaren had 306.

55
A Baku penalty may be worthwhile if the fresh ADUO2 engine helps Ferrari score more consistently later. But the immediate downside is clear: a back-of-grid start for Leclerc creates an opening for McLaren to cut into Ferrari’s 52-point advantage.
53
The bottom line
Leclerc’s expected Baku penalty is not evidence that Ferrari lost the engine from his Monza crash. The team recovered it after sensor and X-ray checks, and is expected to use it cautiously in practice.
18
23
The likely back-of-grid start comes instead from Ferrari’s decision to fit a fresh ADUO2 engine for the competitive sessions. It is a deliberate short-term sacrifice designed to give Leclerc a newer upgraded power unit for the final stretch of 2026.
