Home » Ferrari’s ADUO upgrade failed to hide key weakness at Austrian GP, warns David Croft

Ferrari’s ADUO upgrade failed to hide key weakness at Austrian GP, warns David Croft. Ferrari's power unit concerns remain after Austria despite new upgrade.

David Croft believes Ferrari’s Austrian Grand Prix exposed serious concerns despite latest upgrades

Ferrari arrived at the Austrian Grand Prix hoping that its first ADUO power unit upgrade would mark another step forward in the development of the SF-26. Instead, the weekend raised fresh concerns about both the car’s outright performance and the team’s race execution, with Sky Sports F1 commentator David Croft suggesting the event served as an important reality check for the Scuderia.

Although Ferrari left qualifying with Charles Leclerc starting second and Lewis Hamilton lining up third, the final grid positions arguably painted a more optimistic picture than the team’s actual pace. Incidents that interrupted the final qualifying attempts of several rivals prevented the true competitive order from fully emerging.

Had those laps been completed, the Maranello team may have found itself further down the grid, making its qualifying result somewhat flattering compared to its genuine performance level.

Race pace revealed Ferrari’s true position

Sunday’s Grand Prix quickly exposed the limitations that had been hidden during qualifying. While Lewis Hamilton eventually crossed the finish line in fifth place, he finished more than 26 seconds behind race winner George Russell. Meanwhile, Charles Leclerc endured an even more difficult afternoon, slipping backwards through the field after starting from the front row.

For David Croft, the race confirmed that Ferrari simply did not possess the pace required to challenge Mercedes under the demanding conditions at the Red Bull Ring.

Ghost car analysis highlighted Ferrari’s straight-line deficit

Discussing the weekend on The F1 Show, David Croft explained that one particular piece of qualifying analysis immediately caught his attention. Comparing Ferrari’s onboard data with Mercedes’ ghost car footage clearly demonstrated how much time the Italian side was losing on the straights.

According to Croft’s assessment, George Russell consistently pulled away from Charles Leclerc along the acceleration zones, indicating that Ferrari’s new ADUO-assisted power unit still lacked the efficiency needed to compete with Mercedes over a full lap.

By the time both cars approached Turn 4, Ferrari was reportedly surrendering around 20 km/h compared to its rival. That difference suggested the SF-26 was consuming its available electrical energy much earlier on the straights, leaving significantly less deployment available later in the lap.

Despite introducing its first homologated ADUO upgrade package, Ferrari’s overall power unit package continued to trail its closest competitors in one of the most critical performance areas.

Ferrari’s strategy also came under scrutiny

Croft also questioned Ferrari’s operational decisions during the race, particularly regarding tyre strategy.

Before Sunday’s Grand Prix, Ferrari had reportedly concluded internally that a two-stop strategy represented the faster option around the Red Bull Ring. However, once the race unfolded, the team switched Lewis Hamilton onto an aggressive three-stop strategy much earlier than expected.

The strategic change appeared inconsistent with Ferrari’s own pre-race assessment, creating uncertainty over whether the decision was driven by tyre degradation, changing race circumstances or an attempt to recover performance that simply was not available.

Onboard footage added further evidence that Ferrari struggled to manage tyre wear throughout the race. Both Lewis Hamilton and Charles Leclerc experienced rapid degradation, particularly on the inside shoulder of the tyres, limiting their ability to maintain competitive pace over longer stints.

Silverstone expected to provide a clearer verdict

While Austria highlighted Ferrari’s remaining weaknesses, several factors suggest Silverstone should offer a more representative evaluation of the team’s latest power unit development.

The Red Bull Ring’s high altitude places unique demands on Formula 1 power units, amplifying any shortcomings in energy deployment and engine efficiency. Silverstone’s very different layout, featuring long, high-speed corners and extended full-throttle sections, should provide a more balanced comparison against Ferrari’s rivals.

The British Grand Prix will therefore become an important benchmark for assessing whether Ferrari’s first ADUO upgrade has delivered meaningful progress or whether the gains observed in Austria were largely masked by the circuit’s specific characteristics.

More Ferrari upgrades are already planned

Fortunately for the Maranello squad, development is far from complete. The Italian side is already preparing its second ADUO development token, which is expected to arrive later this summer as part of an ongoing effort to reduce the power unit deficit to Mercedes and the other leading manufacturers.

If that next evolution delivers the performance Ferrari is targeting, both Lewis Hamilton and Charles Leclerc could find themselves much closer to the front during the second half of the 2026 Formula 1 season. However, after Austria, it is increasingly clear that aerodynamic improvements alone may not be enough unless Ferrari also succeeds in closing the remaining gap in straight-line performance.
