Red Bull's Formula One world champion Sebastian Vettel took his fourth win in five races on Sunday in a Spanish Grand Prix that shed its reputation for predictable processions.
McLaren's Lewis Hamilton finished second, just 0.6 seconds behind, after harrying the 23-year-old German over
the closing laps in a far closer finale to a race many had forecast would be a duel between the dominant Red Bulls.
"That was crazy, crazy man, you were coming, coming, coming," Vettel told Hamilton before the podium Champagne celebrations.
Hamilton's team mate and fellow-Briton Jenson Button was third, beating Red Bull's Australian Mark Webber for the final place on the podium and helped by a three-stop strategy to the others' four.
However the stewards announced some 19 minutes after the end of the race that Hamilton, Button and Webber were all under investigation for failing to slow for yellow flags.
The rest of the field, including Ferrari's fifth placed local hero Fernando Alonso and sixth placed Michael Schumacher, were lapped.
Vettel stretched his championship lead over Hamilton, the 2008 champion and only man to have beaten him so far this year, to 41 points.
Vettel's 14th career victory marked the first time since 2000, when Finland's Mika Hakkinen beat Michael Schumacher, that the race was won by someone other than the pole sitter.
At a circuit previously renowed for scant overtaking or excitement, with just 10 moves in last year's race, the new driver operated rear wings (DRS) and KERS systems transformed the landscape as drivers diced and jockeyed for position.
