Ferrari Eyes 2026 Engine Upgrade Under F1's Catch-Up Rules

Ferrari Team Principal Fred Vasseur believes his team will be granted a power unit upgrade this season under Formula 1's new 'ADUO' regulations, designed to help manufacturers close performance gaps. Despite appearing close to Mercedes on track, Ferrari acknowledges a significant deficit, particularly in straight-line speed, which it hopes to address through this regulated upgrade pathway.

Why it matters:

The 2026 engine regulations introduce a novel, performance-based upgrade system intended to prevent a single manufacturer from running away with a dominant advantage. If Ferrari qualifies for and successfully implements an ADUO upgrade, it could significantly alter the competitive dynamic at the front of the grid, offering a more tangible route to challenge Mercedes than minor regulatory tweaks.

The details:

• The Additional Design and Upgrade Opportunities (ADUO) system allows manufacturers lagging in performance to introduce upgrades. Eligibility is based on a secretive ICE Performance Index, not direct lap time comparisons.
• Performance Thresholds:
  • A deficit of over 2% to the benchmark grants one in-season upgrade and one for the following year.
  • A deficit of over 4% grants two in-season upgrades and two for the next year.
• Current Performance Gap: While Ferrari's lap time gap to Mercedes in China was just 0.381%, Vasseur is confident the pure power unit metrics will show enough of a deficit to trigger ADUO eligibility.
• Car Characteristics: Analysis shows Ferrari holds advantages in race starts and cornering, but Mercedes is "well clear" on power and top speed. An engine upgrade is seen as key to mitigating this straight-line weakness.
• Regulatory Timing: The first ADUO window was originally after six races (Miami). Due to cancelled early races, the FIA may adjust the timeline, with teams like Aston Martin-Honda pushing for the earliest possible upgrade opportunity.

What's next:

Vasseur views the ADUO process as a more significant opportunity than upcoming compression ratio rule changes aimed at Mercedes. The FIA's final decision on eligibility and the timing of the first window will be critical.

• Ferrari is pushing on all fronts—chassis, aerodynamics, and energy management—but sees the potential engine upgrade as a pivotal moment to close the gap.
• Successfully leveraging the ADUO system could redefine Ferrari's 2026 campaign, turning it from a consistent challenger into a genuine threat for victories.
