The Halo cockpit safety device threw down a challenge to F1's designers last year, and like his colleagues, Mercedes' James Allison struggled to minimize the component's effects.

Denounced by many as an element adverse to Formula 1's DNA, the Halo's introduction was controversial, but ultimately the FIA viewed its mandatory presence as the best possible option for increasing cockpit safety.

Designed to shield a driver from flying debris and protect in the event of an accident or collision, the Halo's resistance to load is massive.

“This is not a light piece of work, it is several kilograms of titanium that need to be put on the car,” Allison articulately explains in the short video produced by Mercedes and posted on its website.

"We had to strengthen the design of the chassis so that it would be able to take roughly the weight of a London double-decker bus sitting on top..."

Allison insists the Halo will evolve in the future, and eventually enjoy better integration and aesthetics.

"It’s a bit of an acquired taste, and we’re still busy acquiring it and I‘m sure everyone else is too, but I think there are things we can do in coming seasons to make it also look nicer on the car," he added.
