The German manufacturer had originally intended to give the major revamp of its W14 a debut at this weekend’s Emilia Romagna Grand Prix.
However, the extreme weather situation that prompted the calling off of the Imola event meant the opportunity for a first run on a more traditional track has now been lost.
Imola’s cancellation could have prompted a major rethink about Mercedes’ plans, because the next race in Monaco is far from perfect for bringing major new parts.
The street circuit poses a greater risk of accidents, which could wreck any new components early on, and the bumpy layout, low speed corners and fast-changing track surface make it extremely difficult to gather valuable data on aerodynamic performance.
But even though there would have been some logic for Mercedes to wait until the Spanish Grand Prix to introduce the upgrade, it has elected to push on with running the new parts as soon as possible.
It is understood that several factors have prompted it not to have a change of heart.
