FIA revises 2026 F1 terminology for clarity, moving away from 'X-mode' and 'MOM'

The FIA is finalizing a simplified set of terms for Formula 1's 2026 technical regulations, aiming to replace confusing initial labels like 'X-mode', 'Z-mode', and 'Manual Override Mode' (MOM) with clearer language for teams, drivers, and fans. The goal is to establish a unified vocabulary that enhances understanding of the sport's significant technological shift, which includes the introduction of active aerodynamics and a new overtaking aid.

Why it matters:

Clear communication is critical as F1 undergoes its most radical regulatory change in a generation. With DRS being replaced by complex new systems, consistent and intuitive terminology will help fans follow the on-track action and strategic battles, preventing confusion that could detract from the viewing experience. This standardization effort reflects a broader push to make the sport's increasingly technical aspects more accessible.

The details:

• Initial terms like X-mode and Z-mode, later renamed to 'straightline mode' (SLM) and 'cornering mode', are being reevaluated for being overly technical.
• The notably awkward Manual Override Mode (MOM) is likely to be replaced by a simpler term like 'overtake mode'.
• FIA Single-Seater Director Nikolas Tombazis stated the federation wants "a unified terminology used by the teams when they speak to the drivers on the radio, but also by the commentators on TV, and also the same terminology in the regulations."
• The revised terms are expected to be finalized before the end of 2024, with an announcement possible as early as mid-December.

The big picture:

The terminology overhaul is directly tied to the core 2026 technical philosophy. The new active aerodynamics system will see front and rear wings adjust automatically between a high-downforce setting for corners and a low-drag configuration for straights to complement the new power units. Simplifying the language around these constant adjustments is key. Furthermore, the temporary electrical boost for overtaking—a central new racing feature—requires an instantly recognizable name that commentators can use effectively during broadcasts.

What's next:

Once the FIA concludes its collaboration with stakeholders and announces the final terminology, teams and media will begin adopting the new language throughout 2025 in preparation for the 2026 season. The success of this initiative will be measured by how seamlessly the terms are adopted in radio communications, broadcast commentary, and fan discussion, ultimately supporting a smoother introduction of the new-era cars.
