Ryan Hunter-Reay will start Sunday's IndyCar race on the Sao Paulo street circuit from pole position after coming out on top from an eventful qualifying session.
The reigning champion broke Will Power's track record with his 1m20.4312s effort, which left him 0.3 seconds clear of Andretti team-mate EJ Viso.
Dario Franchitti was third-fastest alongside Tony Kanaan, who did a superb job to get himself on the second row considering that he is still feeling the effects of a hand tendon injury sustained at Long Beach.
James Hinchcliffe was fifth-fastest, giving Andretti three cars in the top six, with Scott Dixon set to line up alongside him.
Hunter-Reay's pole aside, the story of the session was the disaster at Penske, which had both Power and Helio Castroneves eliminated in the opening phase.
The pair had not yet banked a lap when James Jakes's car broke down on the circuit and brought out the red flags, leaving Power facing the prospect of having to win from 22nd on the grid if he is to keep his perfect record in Brazil intact.
Tristan Vautier's tough start to the weekend continued when he completed an unfortunate hat-trick of hitting the wall in three consecutive sessions. On this occasion, his downfall came when he launched himself over the Turn 1 kerb and went straight into the Turn 2 wall during the first segment.
That brought out the red flag a few seconds early, costing several drivers including Oriol Servia the chance to complete their final flying lap.
Vautier was docked his two best laps for causing the stoppage, and the next qualifying phase was briefly delayed while the barrier was repaired. The Frenchman is the only driver on this year's grid to have never raced in Sao Paulo previously.
His accident had a knock-on effect for team-mate Simon Pagenaud, who faces the same consequences as the Penske pair for not getting a lap in early.
Sarah Fisher Hartman's Josef Newgarden was forced to sit the session out due to an engine change.
