What is the F1 halo?
The halo is a curved titanium bar above the cockpit, introduced in 2018, that protects a driver's head from large debris and other cars. It was controversial at first on looks and visibility, with critics including Niki Lauda, but it is now widely credited with saving several lives, including Romain Grosjean, Zhou Guanyu, Charles Leclerc and Lewis Hamilton.
What the halo is
The halo is a frontal head-protection structure introduced for the 2018 season after a five-year FIA evaluation, designed to reduce the risk of debris or another car striking a driver's head.[1] It is a curved bar made of grade-five titanium, weighing around seven kilograms, mounted just in front of and above the cockpit.[2]
Why it was controversial
The halo was unpopular at launch.[3] Critics attacked it on aesthetics, visibility and the feeling that it changed the character of an open-cockpit car, with Niki Lauda among the loudest voices, calling it a mistake that destroyed the DNA of an F1 car.[3]
The lives it has saved
The criticism faded as the halo proved itself.[4] It is now credited with protecting Charles Leclerc when a car was launched over him at Spa in 2018, Romain Grosjean in his fiery Bahrain crash in 2020, Lewis Hamilton when Max Verstappen's car rode over the cockpit at Monza in 2021, and Zhou Guanyu when his car flipped at Silverstone in 2022.[4] Despite weighing only about seven kilograms, the structure is built to withstand roughly twelve tonnes, about the weight of a double-decker bus.[2]
:::analysis The halo is the clearest case of safety winning an argument that aesthetics had been losing. Within three years the same device fans had called ugly had visibly saved lives on live television, and the debate simply ended. It is now impossible to picture the cockpit without it.
