KV Racing Technology's Tony Kanaan put in the fastest time in Friday practice, ahead of the qualifying session on the 1.5-mile Las Vegas Motor Speedway that will set the grid for Sunday's IZOD IndyCar World Championship 2011 season finale and title decider.
Oriol Servia, Ryan Hunter-Reay and Scott Dixon completed the practice session in the same positions (second, third and fourth) as they did on Thursday, while Kanaan's KVRT team mate EJ Viso bounced back from the lost track time caused by his engine fluid leak in practice 1 to record the fifth fastest time on Friday.
Once again the session was divided into two parts, with 17 of the 34-car field running for the first half and then the reminder running for the second part. Most of the top times were once again set in the later session as the track got progressively faster - Hunter-Reay had been the fastest of the earlier session ahead of Mike Conway and Alex Tagliani.
Championship contenders Will Power and Dario Franchitti finished some way back in the timings, in 12th and 15th positions respectively. Danica Patrick finished back in 20th place, although her Thursday time remained the fastest of anyone so far.
The only major incident happened very early in the session, when suspension failure sent James Jakes into the wall at turn 2. It was a hard impact and there was black smoke coming from the car, prompting Jakes to extricate himself even before the car came fully to a halt on track: within seconds the wreckage was on fire, and was badly damaged before the fire was put out.
The Dallara chassis was certainly burned beyond repair and will not make it to the official 'retirement party' of the eight-year-old model on Sunday. It left Dale Coyne Racing evaluating what to do about Sunday's race, as the backup car is essentially in pieces at this stage.
Jakes himself was checked for minor burns and released from the infield care centre but will not be able to take part in qualifying.
