Spain. He joined Gutierrez, Daniil Kvyat (Red Bull), Rio Haryanto (Manor) and Kimi Raikkonen in retiring from the season-opening GP.
The race began with pole-sitter and reigning world champion Hamilton botching the start. Hamilton slipped from first to sixth in the blink of an eye as Ferrari's Vettel sped into the lead at the first turn.
From then, Vettel opened up an advantage of more than 11 seconds over the Mercedes ace only for the forced restart to create a logjam in the field - and make tyre choice paramount. Vettel lost top-billing on his soft tyres as Rosberg and Hamilton drove on medium compound tyres for greater durability - and Rosberg soon assumed the lead.
Ricciardo was second for a stint before being overtaken by Hamilton, the Australian then being forced to pit and change his soft tyres, dropping to fifth. He then produced a late charge but couldn't reel in Vettel while Williams' Felipe Massa came fifth, followed by Haas' Romain Grosjean. AAP
