Ferrari Confident New F1 Engine Rules Prevent 'Sandbagging'

Ferrari's engine chief has expressed confidence in the FIA's new system designed to prevent a single manufacturer from dominating the 2026 power unit era, dismissing concerns that rivals could deliberately underperform to gain a development advantage. The Additional Development and Upgrade Opportunities (ADUO) process will allow lagging manufacturers to catch up during the season, a move Ferrari believes is robust enough to prevent gaming.

Why it matters:

The 2026 season introduces the most significant technical overhaul in a generation, with new power units running on 100% sustainable fuel and a 50/50 split between electric and internal combustion power. Preventing a repeat of past eras where one engine supplier locked in a multi-year advantage is crucial for maintaining close competition and the sport's health. The ADUO system represents a fundamental shift from a near-total development freeze to a controlled, performance-based allowance for in-season upgrades.

The details:

• The FIA's ADUO system will measure the performance of all five manufacturers—Mercedes, Ferrari, Red Bull Ford, Honda, and Audi—at three points during the 2026 season (25%, 50%, and 75% completion).
• Any manufacturer deemed to be falling behind on engine performance will be granted additional development tokens or opportunities to close the gap.
• Ferrari's Engine Chief, Enrico Gualtieri, stated the team is "comfortable with the process," believing the regulations are well-prescribed and robust enough to achieve their goal of preventing domination.
• When asked about the risk of 'sandbagging'—where a team might hide its true performance early to qualify for extra development—Gualtieri indicated the rules are designed to mitigate this, though all parties will need time to adapt to the new process.
• Sustainable Fuel Shift: A parallel major change is the switch to fully sustainable, advanced biofuels. Gualtieri clarified that the engine's fundamental "appetite" for specific fuel molecules hasn't changed, but the entire supply chain and feedstock sourcing now have strict sustainability mandates, adding a new layer of complexity for engineers and suppliers.

What's next:

The true test of the ADUO system will come during the 2026 season itself, as the FIA enacts its performance measurements for the first time. All manufacturers are currently deep in the design phase of their new power units, balancing outright performance with the reliability needed to avoid penalties. Ferrari's public comfort with the rules suggests a focus on being competitive from the outset, rather than planning to exploit loopholes. The success of this new regulatory approach will be a key factor in determining whether the 2026 era delivers the close, multi-team competition that Formula 1 desperately seeks.
