Mercedes will bring small updates to the W14 for the Saudi Arabian Grand Prix designed to move the team "in the right direction" according to Toto Wolff.
The team boss believes the track will provide a "different test" after a tough start to the season in which they finished 50 seconds off Bahrain GP winner Max Verstappen.
"This weekend in Saudi Arabia we will learn more about W14, its characteristics and its limitations. It provides a very different test to Bahrain, and it will be interesting to see how the car reacts," said Wolff.
Mercedes has been at-odds over their car concept since Bahrain, with Lewis Hamilton saying the team did not listen to him and Wolff admitting that it was the wrong concept despite hitting their targets in the winter.
The team has started the process of bringing updates this weekend, but they are not going to be "game changers" for them.
"We are bringing some small developments to the car: they won't be game changers, but they can start moving us in the right direction," added Wolff.
"We'll be pushing as hard as we can to create opportunities, and hopefully will give us a better account of ourselves than in Bahrain.
