The German manufacturer is trying to plot a path back to the front of grand prix racing but still has some way to go before it is in a position to challenge Red Bull on pure pace for race wins.
While an upgrade package introduced at the Monaco Grand Prix helped deliver a step forward in form, it continues working hard to try to unlock more performance from the W14.
Speaking ahead of the Hungarian Grand Prix, Lewis Hamilton opened up on how difficult a task Mercedes faces in trying to find the steps it wanted.
"There's simulations with the new rules that we have, and all the new tools we have had to create and understand the flow structures underneath the car," he said.
"All those vortices would blow your mind if you saw what's happening underneath the car, which is a lot different to the previous generations of cars. Working through that just takes time."
Mercedes trackside engineering director Andrew Shovlin has now offered more insight into why it is not yet as on top of the current generation of cars as in the previous rules set.
"With the old regulations, which we had a good grasp on, you didn't need to consider the car in the same dynamic sense," he explained.
"You were just saying it's at a certain roll angle, steer angle, certain ride heights and in doing that, you could capture what was going on.
