Minimum 55% painted surface mandated for 2026 liveries to boost grid differentiation

 

Introducing improvements to the forthcoming 2026 technical and sporting regulations was the meeting’s main goal. With the most significant agreed upon change was related to the visual identity of the cars. It was agreed that a minimum of 55% of the car’s surface area must be covered by painted or stickered liveries as opposed to bare carbon fibre. Bare carbon fibre has become prevalent as teams seek to save weight by not applying paint. While technically efficient, it makes cars look generic. The 55% rule ensures each team’s livery is clearly visible improving the spectacle and making it easier for fans to differentiate cars on track.

Teams realised that paint and vinyl wraps add significant weight. Consequently, many teams began stripping back their liveries leaving large sections of the composite bodywork in raw, black carbon fibre to save grams. This trend became especially pronounced following the introduction of the current technical regulations in 2022. The FIA’s move to mandate a minimum of 55% livery coverage is a proactive step to pre-empt this issue before the 2026 cars are even launched ensuring that the new generation of cars are visually distinct from day one.

According to official release: “It was agreed by Commission representatives that a minimum of 55% of surface area (when viewed from the side and above) must be covered by paint or stickered liveries as opposed to bare carbon fibre surfaces. The objective of this measure is to increase visual differentiation between cars.”

This codifies the FIA’s intervention to prioritise the visual spectacle of Formula One (F1) over the engineering purism of weight saving. It directly addresses widespread fan in addition to sponsor complaints about cars looking to similar due to the extensive use of unpainted, black carbon fibre ensuring that teams display their distinctive, colourful liveries in the 2026 season.

In order to counteract the detrimental aesthetic effects of the weight saving arms race, this is a direct regulatory intervention. Teams have pursued marginal gains by stripping paint (leaving bare carbon fibre) which made cars look dull as well as visually indistinguishable. The FIA is sending a clear message: the commercial and fan facing integrity of the product (the spectacle) outweighs the engineering pursuit of the lowest possible weight. This rule protects sponsor visibility in addition to brand identity ahead of the massive 2026 regulation change which would otherwise intensify the weight saving drive.

Starting in 2026, the grid will be visually more colourful and varied. This directly benefits the fans, sponsors plus the F1 commercial rights holder as the cars will be more easily distinguishable improving the overall television spectacle. Teams that previously relied heavily on exposed carbon fibre to meet the minimum weight limit will be forced to add weight in the form of paint or vinyl to meet the 55% threshold. Compelling engineers to find weight savings elsewhere on the car making the design challenge for the 2026 chassis even more demanding. As the rule is difficult to police that is defining the exact “surface area … when viewed from the side and above.” Teams will likely engage in creative interpretation of the rule, possibly using extreme thin, lighter paints or specific types of vinyl on the minimum 55% area leading to technical debates with the FIA.
