After a disappointing start to the season with its new W14 challenger, Mercedes has been working hard at its Brackley factory on a raft of changes to the car.
As well as seeking overall downforce gains with the latest developments, Mercedes has been eager to deliver a more consistent and stable platform for its drivers.
That is why beyond the obvious visual changes to the sidepods, there have also been tweaks to the front suspension and floor.
As part of F1's regulations, teams have to notify the FIA of any technical changes made to their cars, as well as explain the thinking behind modifications.
Ahead of the Monaco GP, Mercedes duly told the FIA of six key revisions it has made to its car, and the reasons for them.
The changes are:
Front suspension: The top wishbone forward leg inboard pick-up has been lifted. This change results in improved positioning of wishbone wake, which in turn improves onset flow into the sidepod, therefore improving cooling performance.
