The big news for the start of the 2018 season was the implementation of the halo. The halo device is made out of titanium material which has been tested by the FIA to ensure it can handle the heaviest of loads. The halo is fitted to the cars by the teams as the FIA ensure they are tested for the teams to use. With that being said, the halo is able to have some carbon fibre attached to the top of the device.
The halo device with its corresponding mounts weighs somewhere between 10kg to 14kg. The FIA has concluded that the halo is able to withstand a total amount of 116 kilonewtons of force. The only issue with the halo affecting the car is some air flow, and the teams had to take the liberty of focusing on redirecting air flow. According to the drivers, the halo doesn't affect their vision when driving around the circuits.
The crash was caused by the Renault driver Nico Hülkenberg, who unfortunately misjudged his breaking zone. The Renualt rammed into the back of the McLaren of Fernando Alonso causing him to be launched over Charles Leclerc.
The picture above shows the crash at turn one, it shows the McLaren of Fernando Alonso being launched over the top of the Sauber of Charles Leclerc. Since the crash happened, drivers, commentators, and fans have mixed reactions on how the halo performed. The overall reaction to the halo's performance is mixed, as some believe that the halo stopped the tyre from hitting Charles Leclerc. Others believe that the tyre would not have hit Charles Leclerc.
This picture shows the damage done to Charles Leclerc's Sauber; the halo is structurally fine, but the tyre from the McLaren has left black marks. Chassis elements have been ripped off of the car as well as the back wing.
Charles Leclerc was able to get out of the car perfectly fine and obtained no injuries. Fernando Alonso was also perfectly fine when he got out of his crashed McLaren, and he also obtained no injuries.
I am not sure whether the tyre of Fernando Alonso's McLaren actually would have hit Charles Leclerc, however, I believe that it is better than the community is deciding if the halo did work rather than halo not working and a driver gets injured.
I think that the halo is not the prettiest device. However, I think that it might not have helped in this instance but, it is a great safety precaution which could save a drivers life in the future. With that being said, it is good that this device is implemented as it lowers the risk of the sport.
Ferrari's Upgrade to the Halo
Ferrari attached the mirrors to the halo which the FIA allowed, except from the fact that they also attached some winglets. The FIA believed that the winglets were there to support the mirror on the halo. However, after further investigation, they came to the conclusion that they looked like the only thing they provide is aerodynamics rather than support for the mirror on the halo. So even though the winglets have been removed, the mirrors are still attached to the halo.
