After picking up a five-place grid penalty for a grid box change, Hamilton will start the Bahrain Grand Prix in ninth.
Hamilton will be eager to exact revenge over Sebastian Vettel after finishing runner-up to him at the Australian Grand Prix.
Mercedes may opt to use the soft tyres in Bahrain to prevent overheating to the car.
While the Bracknell-based manufacture worked hard during the season to develop the V09 model, Hamilton admits Ferrari’s engine is just as good as theirs if not better.
“I guess it ultimately proves everyone who said we had a party mode in the last race wrong,” he said.
“Ferrari have done a great job this weekend, they’ve got the pace and it’s been a difficult weekend for me overall in general. I hope I can turn it upside down.
“We come to a hotter circuit and often the gap closes a little bit because the Ferraris maybe have an upgrade, their engine mode is easily as good as ours.
“As you could see this weekend on the straights they are just as quick if not quicker.
“When you get to a hot circuit it’s really difficult to keep the temperatures low in the tyres and that’s something they’ve always been good at.”
Mercedes chief Toto Wolff thinks the soft tyres as opposed to supersofts may be the best strategy for the race later today.
He said: “I was genuine about it. I meant it. On a track like Bahrain, with a very abrasive surface, and lots of heat, we struggled.
“On the softs, the car was much better, but putting the softer compound on, the supersoft, it looks like we’re overheating and therefore not extracting the optimum grip.”
