The 1999 San Marino Grand Prix (formally the Gran Premio Warsteiner di San Marino 1999) was a Formula One motor race held at Imola on 2 May 1999. It was the third race of the 1999 Formula One World Championship.
The 62-lap race was won by German Michael Schumacher, driving a Ferrari, after he started from third position. Finn Mika Häkkinen took pole position in his McLaren-Mercedes, but crashed out after 17 laps. Häkkinen's teammate, Briton David Coulthard, finished second, with Brazilian Rubens Barrichello third in a Stewart-Ford.
Report
Race
Mika Häkkinen took an instant lead from David Coulthard and Michael Schumacher after the start. Eddie Irvine was ahead of Rubens Barrichello, Heinz-Harald Frentzen, Ralf Schumacher, Damon Hill and Jean Alesi. Jacques Villeneuve was left stranded on the grid after a clutch problem. In an unforced error, Häkkinen crashed out at the final Traguardo chicane on lap 17, allowing David Coulthard into the lead ahead of Michael Schumacher.
Meanwhile, Schumacher's teammate Irvine had settled in third place following Häkkinen's retirement. He was forced to retire from the race himself when his Ferrari engine expired on lap 47. Frentzen span off shortly afterwards on the oil left by Irvine's Ferrari. This allowed Hill to inherit third place, but he made his final stop in a three stop strategy two laps later. Barrichello was consequently promoted to third place which he held until the end of the race ahead of Hill.
