He added: "We will regather as a team and come back fighting".
"It is, of course, hugely satisfying to be back on the top step of the podium with Seb", Marchionne said.
"They are strong in race trim and we particularly struggle with the rear end".
The three-time world champion said the penalty was a setback, but that his Mercedes may not have been fast enough to overhaul the triumphant Ferrari of Sebastian Vettel. The win also helped Scuderia Ferrari leapfrog rivals Mercedes in the constructors' championship race. A demoralizing drought for such a fiercely proud team, certainly, but this year promises to be different.
"I'm really enjoying it, the vehicle has been a pleasure".
"All this is the fruit of superb work at the track and in Maranello, so my compliments not just to Seb for his achievements in Bahrain, but also to the whole team".
Vettel and Hamilton were tied with a win each, but Vettel's second victory and 44th of his career puts him in command heading into the Russian GP in Sochi on April 30.
"I think we are about equal", he said.
"It was a really great team effort today". The Finn nearly lost his third place too had the race been two laps longer, as Kimi Raikkonen had closed the gap to one second by the end.
Valtteri Bottas felt the pain of Mercedes team orders for the first time at the Bahrain Grand Prix on Sunday but said he accepted they made sense in the circumstances.More news: Celebrate Earth Day by Marching for Science in St. Pete
"It was really hard to follow but we generally had similar pace". Fortunately for Mercedes he was able to hold off Ferrari's Kimi Räikkönen who finished fourth.
Over the years, nothing changes.
Hamilton had pitted behind Valtteri Bottas, who had started on pole but finished third, and because both Mercedes drivers came in under the safety auto at the same time the Briton had to wait while his team-mate took new tyres. "Losing points for the team is definitely painful".

Hamilton's start on Tuesday was hampered by a cable plug reportedly falling out and halting his vehicle after just a few laps.
"Yeah, completely my fault with the safety auto".
Hamilton had been on pole for six races in a row until Bottas broke the sequence in Bahrain and Wolff said Mercedes appeared to be still slightly ahead of Ferrari on single lap pace.
Hamilton was handed a five-second penalty for a pit lane infringement which ultimately cost him dearly. He then pitted from the lead to take Soft tires on Lap 10, getting the undercut on Bottas and Hamilton and reentering in 12th.
Despite twice being let through by team-mate Valtteri Bottas, Hamilton was unable to chase down Vettel and had to settle for second, finishing 6.6 seconds behind the Ferrari driver.
