Formula 1’s governing body is revising the technical language used to describe the sport’s revolutionary 2026 power unit and aerodynamic systems, aiming to create clearer communication across teams, broadcasters and fans. The move comes after initial terminology introduced with the new regulations proved too complex for widespread understanding.
Confusion over initial technical naming prompts rethink
When the FIA unveiled its groundbreaking 2026 technical framework during last season’s Canadian Grand Prix, the governing body introduced several new concepts to explain how cars would operate under the dramatically altered ruleset. The original nomenclature included X-mode, Z-mode and Manual Override Mode to describe different aerodynamic and power deployment states.
These terms quickly demonstrated their limitations. The Manual Override Mode became commonly abbreviated to MOM, creating potential confusion in team radio communications and broadcast commentary. Even after the FIA revised X-mode and Z-mode to straightline mode and cornering mode respectively, with teams further shortening the former to SLM, satisfaction with the clarity remained elusive.
The challenge stems from the fundamental transformation of how Formula 1 cars will generate performance from 2026 onwards. Traditional DRS zones will disappear entirely, replaced by active aerodynamic systems that allow all drivers to adjust both front and rear wing elements on every straight section of track. Meanwhile, a temporary electrical power boost from the hybrid systems will provide an overtaking aid when drivers close within one second of the car ahead.
Standardisation across all stakeholders drives new approach
FIA single-seater director Nikolas Tombazis addressed the terminology revision during a media briefing in Abu Dhabi, emphasising the federation’s commitment to unified language that spans regulatory documents, team communications and broadcast coverage.
“We are revising some of the terminology because we want to make it clear and we want to make it simple for the fans to understand what’s happening,” Tombazis explained. “We want to have 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 Greek engineer confirmed that the FIA is conducting a comprehensive exercise to ensure simplicity while maintaining technical accuracy. Crucially, the governing body is collaborating with various stakeholders in Formula 1 to reach consensus on the final terminology before implementing it across all official channels.
Simpler terms expected before year end
Although Tombazis declined to reveal the precise wording during his Abu Dhabi briefing, he indicated that final decisions would materialise before the calendar year concludes, potentially as soon as mid-December. Early indications suggest Manual Override Mode may transition to the more intuitive “overtake mode,” directly communicating its purpose to audiences unfamiliar with the technical intricacies.
The distinction between what began as X-mode and Z-mode may be simplified further still. Rather than maintaining separate terms for straightline and cornering configurations, the FIA appears ready to adopt “active aerodynamics” as an umbrella description. This reflects the reality that all 2026-specification cars will utilise identical wing setting principles: higher-downforce configurations through corners for mechanical grip, and low-drag configurations on straights to maximise the efficiency of the new power units.
The adjustment represents a pragmatic acknowledgment that overly technical language serves little purpose when every team follows the same fundamental approach dictated by the regulations. The low-downforce straight-line setup becomes particularly critical under the 2026 framework, where reduced drag is essential for the new power unit architecture to function as intended.
What this means for the 2026 season launch
Finalising terminology before the new year allows teams, broadcasters and media organisations sufficient preparation time before the 2026 season begins. Clear, consistent language will prove essential as Formula 1 explains its most significant technical revolution in decades to both dedicated enthusiasts and casual viewers.
The simplified approach aligns with Formula 1’s broader strategy of maintaining technical sophistication while improving accessibility. As active aerodynamics and enhanced hybrid deployment reshape racing dynamics, ensuring everyone uses the same intuitive terms will help audiences understand the strategic decisions unfolding during races. The changes should be formally documented in updated regulatory texts and media guidelines well before teams conduct their first pre-season testing sessions with the new-generation machinery.
