Halo

Halo
Developed at the Cranfield Impact Centre, the halo was brought in to protect drivers’ heads from wheels, broken wings and other dangerous debris sometimes sent flying during crashes. Cranfield manager James Watson spoke about the halo’s development and capabilities in an interview with Motor Sport following Romain Grosjean’s harrowing Bahrain 2020 crash, where the halo almost certainly saved his life. “We tested it to take over 100 Kilonewtons,” he said (roughly the equivalent of 10.2 tonnes, or two African elephants landing on it simultaneously). “It’s difficult to work out what the exact force [of Grosjean’s accident] was, but the fact that it remained intact would imply that it was less than what was actually tested.” Since its introduction, the halo has protected drivers such as Romain Grosjean, Charles Leclerc and Valtteri Bottas in some of F1’s biggest accidents.
