Mercedes have completed a filming day with the W13 at Paul Ricard, which reportedly sported the upgrades the team were planning on introducing at Barcelona this weekend.

Multiple reports have suggested the filming day took place behind closed doors in France on Wednesday with George Russell behind the wheel, although the team has not officially confirmed the running on its website or social media channels.

Ferrari also took part in a similar filming session at Monza last Friday, which saw the Scuderia reportedly trial their own upgrades for the Spanish Grand Prix with Charles Leclerc behind the wheel.

Teams are allowed two filming days per year with their current cars and, while they are limited to 100km of running per session, there is no rule against the specification of car they run, leaving room to test new upgrades in that time.
