- Ferrari see chance to gain ground under new 2026 engine rules.
- Early races expose a key performance gap against Mercedes.
- Mid-season decisions could shape how the title fight unfolds.
Ferrari has set its sights on a mid-season power unit upgrade under Formula 1’s new ADUO rules, as team principal Fred Vasseur points to a clear engine deficit against Mercedes in the opening races of the 2026 season.
After two grands prix, the Italian team sits as Mercedes’ closest rival, but lacks straight-line speed, a weakness Vasseur believes could qualify Ferrari for regulatory relief. The claim draws on early data, which details how the new system could reshape the competitive order.
The issue is not just what fans see on track. Vasseur argues that Ferrari’s engine performance, measured independently by the FIA, may fall outside the allowed margin. If that proves true after six races, Ferrari could gain a rare chance to upgrade its power unit during the season.
The gap to Mercedes and what it means on track
The season opened with a clear pattern. Ferrari launches well and holds pace through corners, but Mercedes pulls away on the straights. That split has defined the first two races.
In China, the gap looked small on paper. Kimi Antonelli took pole with a 1m32.064s lap, while Lewis Hamilton clocked 1m32.415s for Ferrari. Yet Vasseur made it clear the numbers hide a deeper issue.
“I would prefer to be a bit faster,” he said, according to The Race. “We know that we have a deficit of performance mainly in the straight line that we have to work on.”
That half-second gap comes largely from engine power, not handling. Ferrari can fight in corners, but it cannot match Mercedes in a straight line.
How ADUO works
The 2026 rules introduced Additional Design and Upgrade Opportunities, or ADUO, to keep engine makers close. The system checks each power unit on its own, not by lap time.
If an engine is more than 2% behind the best after six races, the team gets one upgrade later in the year and another before 2027. A gap of 4% allows even more changes.
According to The Race, the FIA uses an internal index to judge this. It looks at power and energy output, though the exact method stays secret. This means a team can look competitive on track but still qualify for help if its engine underperforms.
That is where Ferrari sees hope. Vasseur believes the data will show a clear shortfall, even if race results suggest a tighter fight.
Vasseur’s strategy: ADUO over compression ratio changes
Vasseur does not expect much from the upcoming rule tweak on engine compression ratios. From June 1, the FIA will check the 16:1 limit both when engines are cold and hot, closing a loophole some believe Mercedes used.
Mercedes says it will not lose speed. Rivals are not sure. Still, Vasseur downplays the impact.
“I’m not convinced that the new compression ratio rule will be a game changer, a huge game changer,” he said. “It’s more that you will have the ADUO at one stage, and that the addition of the ADUO will be an opportunity for us to close the gap.”
He also stressed that Ferrari must improve across the board. The team will push its engine, car design, and aerodynamics together, not rely on rules alone.
“I don’t want to do the split between chassis and power unit. I want to push everywhere, but we know that we have to improve on the ICE. But this will be for after the ADUO, on energy, on chassis, on aero. We are pushing like hell on every single area to close the gap,” he added.
The timing of any upgrade remains unclear. The rules say the first ADUO window opens after six races, which should have been Miami.
But race cancellations in Bahrain and Saudi Arabia pushed that mark back to Monaco in June. This delay could slow Ferrari’s plans.
According to The Race, the FIA now wants to adjust the timeline. Officials may set a fixed date or revise the race count. Other teams, including Aston Martin and its Honda partner, also want a faster decision.
The broader political landscape
The fight goes beyond lap times. Mercedes boss Toto Wolff has already warned of pressure behind the scenes after his team’s strong start.
“Let’s see what kind of political knives are going to come out,” he said after Antonelli’s win in China.
Ferrari is active in these talks. It supports current start rules, which play to its strength off the line. Vasseur had earlier backed a smaller turbo design to improve starts, a choice that now pays off.
He has resisted further rule changes. “At one stage, enough is enough,” he said, pointing to recent tweaks that already hurt Ferrari.
Meanwhile, teams plan fresh talks after Japan to review energy rules. Ideas include changes to fuel flow and how energy is used during races.
Ferrari enters this phase in a delicate spot. It can challenge Mercedes in races, but its engine data may tell a different story. If Vasseur is right, ADUO could give Ferrari the tool it needs to close the gap.
If not, the team may spend the season chasing a rival that already holds the upper hand.
