Mercedes is set to debut their upgraded power unit at the opening race of the delayed 2020 season in Austria, a move aimed at addressing reliability concerns.
The team's solid performance during pre-season tests in February was overshadowed by concerns about the power unit's reliability, but the latest update is expected to alleviate these issues.
Mercedes has used the extended break to make further improvements to their W11 chassis, which will be unveiled in its new black livery.
"We have a different spec to Melbourne because we have made reliability updates since then," a Mercedes spokesperson told Motorsport.com.
Mercedes has also confirmed that chassis updates are ready to be implemented for the season opener, with technical director James Allison stating that the team had made significant progress in the wind tunnel and design departments since the launch car.
"We got quite a lot of ideas about how to make it quicker, and quite a lot of those ideas were already in process through the design office before we were forced to shut down nine weeks ago," Allison said.
Red Bull is also bringing an upgraded chassis and an updated Honda engine, while Ferrari's revamped SF1000 will not be ready until at least the third round in Hungary.
