Lewis Hamilton said Mercedes must "leave no stone unturned" in their quest for improvements after he battled to a fourth-place finish at the Australian Grand Prix.
The seven-time world champion has endured a frustrating start to the 2022 campaign, sitting fifth in the drivers' championship standings and repeatedly speaking out on problems with the team's W13 car.
Hamilton batlled to fourth in the third Grand Prix of the season after starting fifth on the grid, with team-mate George Russell claiming his first podium finish for Mercedes in third as Ferrari's Charles Leclerc stormed to victory.
After describing Mercedes' car as "spiteful" in the aftermath of qualifying in Melbourne, Hamilton stressed the need for the team to make improvements in "every single area" if they are to compete with early-season pace-setters Ferrari.
"I will be on Zoom calls with our bosses, really trying to rally them up," he said.
"We have got some improvements that we need to make, and we need everyone's support in doing so.
"It is about making sure we leave no stone unturned, that the hunger is there, and we are maximising every moment.
"I will be chasing the people in the wind tunnel, the aerodynamic guys, and just looking at every single area.
"There is performance to be gained and we need it now, not in two or three races. I have got to keep that encouragement and energy high."
Mercedes are bidding for a ninth consecutive constructors' championship, but trail Ferrari by 39 points in the 2022 standings after three races.
While calling for improvements across the board and noting that the gap to Ferrari is "pretty big", Hamilton stressed the need for the team to remain upbeat and highlighted that there are many races to come.
"I prefer to stay optimistic," he added. "There are 20 races to go.
"I am really hoping we can get in the fight, but with every bit of improvement we make so will Red Bull and Ferrari.
"It is not going to be easy. The gap is pretty big right now, but there is a long way to go."
Russell, meanwhile, is second in the drivers' standings after following up his fourth and fifth-place finishes in Bahrain and Saudi Arabia with an impressive showing at Albert Park, and Hamilton was keen to praise the 24-year-old for his performances since making the switch from Williams.
"It is incredible," Hamilton said of the start Russell has made to his Mercedes career.
"He has been so solid. He is really grafting away and is doing an amazing job."
The next date in the Formula One calendar will see Hamilton bid for a repeat of his 2020 triumph at the Emilia Romagna Grand Prix, after he finished second to Max Verstappen at Imola last year.
