Fernando Alonso's 2016 Australian GP crash advanced halo safety device

March 20, 2026

Fernando Alonso's high-impact crash during the 2016 Australian Grand Prix provided key data that propelled Formula 1's adoption of the halo head protection device. The incident highlighted vulnerabilities in cockpit safety and influenced the FIA's research efforts. Simulations later confirmed the halo's effectiveness in similar scenarios.

Fernando Alonso’s 2016 Australian GP crash advanced halo safety device ## Incident details On lap 17 of the Australian Grand Prix on March 20, 2016, Fernando Alonso, driving a McLaren-Honda, attempted to overtake Esteban Gutierrez's Haas for 19th place at Turn 3. Alonso struck the rear wheel of Gutierrez's car, lost steering control, hit the outside wall, slid into grass and gravel, and rolled before resting upside down near a tyre barrier. Alonso exited the wreckage on his feet, though shaken, and was later diagnosed with a pneumothorax and broken ribs, causing him to miss the next grand prix. ## Impact forces and investigation Data from accelerometers and ultra-high-speed cameras, installed in F1 cars since 2015, revealed extreme forces: 313 km/h at initial contact, 45G lateral deceleration on wall impact, 46G during the roll, 0.9 seconds airborne, and 20G longitudinal acceleration on rear landing. The driver's head struck the left side of the headrest twice. Laurent Mekies, then managing director of the FIA’s research institute, stated: “What we want to understand is the exact dynamics of the head, neck and shoulders in a crash with high g-forces, and how they interact with other parts of the cockpit environment such as the head protection, the HANS, the harnesses and everything that may be in the space around the driver.” The FIA investigated, incorporating findings into head protection research, including halo and Aeroscreen evaluations. ## Halo simulations Less than three months later, the FIA published conclusions. Early 2017 simulations of the crash with a halo were positive. Mekies noted: “We flipped one of our chassis with a halo. We put Andy Mellor inside to assess the worst-case scenario and asked him to get out, precisely in Fernando’s position. Incredibly, he managed it.” This contributed to barriers falling for halo implementation, with F1 cars featuring it by winter 2018.
