Mercedes teammates Lewis Hamilton and Nico Rosberg sped away to their fourth straight one-two finish at the Spanish Grand Prix on Sunday in a dominant performance that does not bode well for the rest of the Formula One field.

Hamilton took off from the pole position and stayed ahead of Rosberg - despite the German closing to less than a second in a tense final lap - to record a fourth consecutive victory and move ahead of his teammate in the overall standings.

Hamilton's 100 points after five races put him three points ahead of Rosberg, who failed to find a way in front of his rival for a fourth straight time after winning the season opener.

His 26th career win gave Hamilton one more than former world champions Niki Lauda, who now works for Mercedes, and Jim Clark.

Hamilton set himself on course to add to his own title from 2008. He hadn't led the championship since June 2012 after winning the Canadian GP with McLaren.

"This is our fourth one-two, it's just unreal," Hamilton said after Rosberg helped douse him in champagne to celebrate his first victory at the Barcelona-Catalunya circuit.

"Getting my first win here after trying for eight years, it is difficult to put into words my feeling. I have never had a car like this. I have never had a gap like this. I am grateful I was able to keep (Rosberg) behind me."

Red Bull's Daniel Ricciardo finished third for his first career podium after coming close on three occasions this year.

Four-time defending champion Sebastian Vettel had a flawless drive to move up from a 15th-place start to finish fourth, with his Red Bull finally not having any problems following two days of it stalling in practice and qualifying.

Valtteri Bottas of Williams was fifth, followed by struggling Ferrari duo Fernando Alonso and Kimi Raikkonen in sixth and seventh.

Lotus' Romain Grosjean and Force India pari Sergio Perez and Nico Hulkenberg rounded out the points.

McLaren made no progress with Jenson Button and Kevin Magnussen coming in 11th and 12th.

Not even a three-week break for their rivals to improve their cars prevented Mercedes from earning its fifth win in as many events this year in a disheartening display for the other 10 teams. Ricciardo ended up more than 48 seconds slower than Rosberg.

Alonso was left in a distant third place in the standings with 49 points, followed by Vettel with 45.

Mercedes increased its lead in the constructor's championship race to 197 points. Red Bull is second with 84 points, with Ferrari trailing in third with 66.
