Brazilian Rubens Barrichello has taken pole position at his home Grand Prix.
1 R Barrichello 1:10.646
2 JP Montoya 1:10.850
3 K Raikkonen 1:10.892
4 F Massa 1:10.922
5 J Button 1:11.092
6 T Sato 1:11.120
7 R Schumacher 1:11.131
8 F Alonso 1:11.454
The Ferrari star brought the crowd at Sao Paulo's Interlagos circuit to its feet with a lap of one minute 10.646 seconds to beat Juan Pablo Montoya.
Montoya was 0.204secs adrift in his last race for Williams, with McLaren's Kimi Raikkonen third and Brazilian Felipe Massa fourth in the Sauber.
Jenson Button will line up fifth, David Coulthard 12th and Michael Schumacher 18th after a 10-place penalty.
The world champion was forced to take the spare car after damaging his race car in a crash in free practice.
That meant he broke the rule that demands drivers must use only one engine throughout a race weekend, and was given the regulation 10-place penalty.
But Schumacher was in any case 0.740secs adrift of Barrichello's pole time.
Coulthard's performance was equally disappointing.
Without a drive for 2005, the Scot was more than 0.8secs slower than team-mate Raikkonen.
Barrichello is chasing a dream victory in his hometown after failing to finish the Brazilian Grand Prix at the last nine attempts.
And he is desperate to become the first Brazilian to win here since his late mentor and hero Ayrton Senna in 1993.
"It is so amazing how life is at this moment," said Barrichello.
"I just tried my best and as I went across the line and saw I was on pole my legs were numb because I had such immense pressure.
"If you make a mistake they would probably come down out of the grandstand and kill you or something like that. But it is good pressure, a good energy all around.
"We are in the same place as we were last year but it is step by step.
Raikkonen will line up third in the McLaren
"I have a very, very good car and there is a good chance of winning the race. That is the biggest step."
Montoya said: "I am very happy. It is my last race
for Williams and I want to thank everyone back at the factory.
"I am going to try to do the best for them tomorrow and it is going to be exciting.
"Hopefully I am going to get a good start and I can keep up with him.
"They are normally very quick but my car has been feeling very good here and we should be very strong."
