Mercedes executive director Toto Wolff has hailed his team's achievement this season, saying it's been "quite rewarding".
Having finished a distant fifth in the Constructors' Championship last year, not too much was expected from the Brackley-based squad this season.
However, they proved their critics wrong as Nico Rosberg and Lewis Hamilton won three races between them and helped the team to finish second behind runaway winners Red Bull in the standings.
Although they fell well short of matching Red Bull and Sebastian Vettel in the end, Wolff is pleased with the progress they made this campaign.
"Finishing last year where we were, you couldn't have expected to be fighting for second place in the Championship, so that is above expectations," he told ESPNF1. "That has been quite rewarding."
Mercedes have made major changes to their personnel in recent years and Wolff believes outgoing team principal Ross Brawn should take most of the credit.
"I think Ross initiated the change process a year ago, getting in some good people and changing the structure a little bit," he said. "When we came in we just added another bit; it was about getting the right resources from Daimler, keeping Ross and the other guys' bags free from politics, getting the right environment.
"Be it from Germany, be it around the races - the relationship with the commercial rights holder was not perfect - I think the funds weren't there that you needed to compete at the top level and these are the kind of things that I added."
