Mercedes AMG Petronas began the new F1 season in similar fashion to the last one, by recording another one-two in Melbourne on Sunday.
World champion Lewis Hamilton dominated the Australian Grand Prix and got his world title defence off to the perfect start.
The Briton controlled the race from start to finish to keep his Brackley team-mate Nico Rosberg at bay throughout as the pair kept well clear of the rest of the field.
Hamilton said: “My team did an amazing job today.”
Rosberg added: “I was trying every lap to my maximum and I will do all year.”
Loutus had a disappointing start to the season with both cars going out on the first lap.
The cruel hand of fate dealt a bitter blow for the Enstone team. Pastor Maldonado was pitched into a spin from behind, resulting in his car hitting the barriers, before Romain Grosjean suffered from a loss of power, and retired at the end of the first lap.
Maldonado said: “It’s disappointing because it was a great chance for us to have a great race.”
Grosjean added: “The first race is always a bit of a tricky one, you never know what might happen and, unfortunately, it was bad luck for us today but I’m still very hopeful for the year.”
