Lewis Hamilton bagged the Bahrain Grand Prix title ahead of his team-mate Nico Rosberg in just one second on Sunday, held at Sakhir.
The Mercedes team was all in high note as they recorded their second grand prix title, just eight days after Hamilton's victory, last weekend in Malaysia.
Rosberg was on a faster tyre, but Hamilton succeeded by showing aggressive defence.
The third place was secured by Force India's Sergio Perez, ahead of Red Bull's Daniel Ricciardo.
The Australian was swift to bypass Nico Hulkenberg, but with four laps to go, Sergio suffered energy-harvesting issues in his Mercedes power unit.
The race was tight after Hamilton took a lead with a better start, while Rosberg started from the pole.
"Nico drove fantastically well throughout, very fair ... He was very fast on the option tyres at the end. I was on a knife edge throughout but it was great fun," Hamilton said.
Hamilton was leading 9.5 seconds by lap 40, when the safety car was enabled following a terrible collision between Lotus' Pastor Maldonado and Sauber's Esteban Gutierrez. The accident led to Maldonado's car rolling up in the air and being awarded 10-second stop-go penalty.
On lap 47, Paddy Lowe, executive director of Mercedes Formula One, told both drivers to "make sure you bring both cars home."
Rosbgerg was adamant to surpass Hamilton and kept on trying to overtake, but Hamilton was smooth in defence to block him every time he chanced upon.
With four laps to go, as the edge slowly went off Rosberg's tyres, Hamilton took the due opportunity to end first in the final pit.
"I strongly dislike finishing second to Lewis but on the other hand it was the most exciting race I have ever had in my whole career ... Today was a day for the sport. I hope you all had a lot of fun ... The team played it as fair as they possibly could today. Let us race flat out. I don't think you need any more evidence that we are here to race and there are no team orders," said Rosberg.
