Upcoming Formula 1 seasons will present a transformed appearance to spectators familiar with recent years. Substantial modifications to engine and chassis rules will lead to considerable shifts in the competition format itself.
The Drag Reduction System (DRS) will be phased out, as all drivers will access a form of DRS on straight sections via active aerodynamics, utilizing both front and rear wings. To retain an overtaking assistance feature, the revised regulations incorporate a short-term electrical power increase from hybrid components for drivers trailing by less than a second.
At its official unveiling of the 2026 regulations during the previous year’s Canadian Grand Prix, the FIA initially designated these operational modes as X-mode, Z-mode, and Manual Override Mode. Yet, this terminology was deemed overly intricate and perplexing for enthusiasts, particularly given that the final mode was soon abbreviated to MOM.
Subsequently, X-mode and Z-mode underwent a name change within the rulebook, becoming straightline mode and cornering mode, with teams swiftly adopting SLM as a shorthand for the former.
The FIA remains unsatisfied with these current terms, leading to another revision of the 2026 terminology. The governing body aims for standardized language to guarantee consistent usage across all teams, drivers, media outlets, and supporters.
“We are reviewing certain terms to enhance clarity and simplify comprehension for spectators regarding ongoing developments,” Nikolas Tombazis, the FIA’s single-seater director, informed a group of journalists, including Autosport.

“Our objective is to establish consistent terminology that teams utilize in radio communication with drivers, that television commentators employ, and that is also reflected uniformly within the regulatory framework. Therefore, we are currently undertaking an effort to develop straightforward language.”
At a press conference in Abu Dhabi, Tombazis refrained from disclosing the precise decisions, although these are anticipated to be finalized prior to the current year’s end, possibly as soon as the following week (beginning December 15th).
He stated, “I prefer not to delve into the exact specifics of each term at this moment, as we are also engaging with additional interested parties on the matter. However, we are actively considering it.”
Early suggestions indicate that “Manual Override Mode” might be simply renamed “overtake mode.” Similarly, what were initially known as X-mode and Z-mode could potentially be collectively termed “active aerodynamics.”
The FIA now views the detailed distinction between the two modes as unnecessary, given that all vehicles will fundamentally employ identical wing configurations across various track sections: a standard, high-downforce setup for turns, and a reduced-downforce arrangement for straightaways. This latter configuration is crucial for minimizing aerodynamic resistance, thereby enabling the effectiveness of the updated engine rules.
