Mercedes has unveiled its biggest upgrade package for over four months ahead of this weekend's Bahrain Grand Prix in Malaysia.
The W17s of F1 drivers' championship leader Kimi Antonelli and George Russell possess a total of seven updated components as the team aims to cement its dominance this season over the final third of the campaign.
Antonelli heads into Sunday's race at the Sepang International Circuit with a 66-point lead over Russell. The nearest challenger from another team is Ferrari's Lewis Hamilton, who is 103 points adrift of the 20-year-old Italian.
In the constructors' championship, Mercedes holds a 160-point lead over Ferrari, with reigning champions McLaren a further 72 points adrift.
The cars this weekend are sporting a heavily modified floor, which includes modifications to the floorboard, the leading edge, corner and body.
The rest of the upgrades relate to the rear of the car, namely the suspension, as well as optimisation of brake drum winglets.
It is the most significant array of updates on the cars since the Canadian GP in May. Rivals Ferrari, McLaren and Red Bull have all introduced major packages on their cars at a steady rate.
After the Dutch GP, team principal Toto Wolff stated that Mercedes did not have "the money to put developments on the car", and that it was "trying to evenly split" its upgrades through the season.

What have other F1 teams brought?
While Mercedes' rivals have not arrived in Malaysia empty-handed, their upgrades are minuscule in comparison.
McLaren has brought a new engine cover to facilitate the cooling demands of the Sepang track.
Red Bull has introduced a modified floor, while Ferrari has named a localised development around the diffuser winglet at the rear of the car.
In the midfield teams, Racing Bulls has made changes to both the front and rear wings, while Haas has updated its rear impact structure.
Finally, Alpine has trimmed the front brake drum exit to increase brake cooling around the track, with temperatures expected to consistently be over 30°C this weekend.
Williams, Aston Martin, Audi and Cadillac have all not listed any new parts for the race weekend.
