Mercedes has become the latest Formula 1 team to complete the FIA's tougher crash tests for 2016.
The Brackley-based outfit, which is chasing its third consecutive championship double this season, joins a host of other outfits in completing the FIA's homologation requirement.
Mercedes executive director Paddy Lowe said recently that the team had had to do a lot of work to comply with a new requirement for improved driver head protection.
The change has meant a significant increase in the forces that the side of the cockpit must withstand.
“It is a very significant increase,” he said in a video released by his Mercedes team. “It is five tonnes of load that the chassis has to take sideways.
“It is intended to significantly increase the protection for the drivers should major pieces of debris, including a whole car, arrive at this point [of the cockpit].”
He added: “It has been a big job for the people concerned with designing chassis, because it is a very significant load increase."
