The second session of practice for the Italian Grand Prix would see Jordan's Timo Glock out onto the track first. He would be joined by several other drivers including Toyota's Ryan Briscoe and Jaguar's Bjorn Wirdheim. Briscoe would move to the top of the times. Other cars would take to the track including BAR's Anthony Davidson.

BMW WilliamsF1 driver Antonio Pizzonia would move into second with a 1m:23.155, while Davidson would go fastest with a time of 1m:21.745. WilliamsF1's Juan Pablo Montoya would  move into second, a time of 1:22.905, to be in front of his team-mate. But Pizzonia would fight back and with a time of 1m:22.526 again occupy second. Juan Pablo would improve his time but not enough to challenge Antonio.

For Jordan's Nick Heidfeld his session would come to a quick end when he was to stop on the side of the circuit with a problem. It was later found that he suffered an engine failure, which will cost him ten places ion the grid. He would not take part in the rest of the practice. Coulthard can only manage eleventh on his first run. Now we would see Sauber's Felipe Massa move into fifth with a 1m:22.807. As for Coulthard his next run would see him improve to jump into third, with a time of 1m:22.394.

McLaren team-mate Kimi Raikkonen would move into second after his first flying lap, a time of 1m:22.018. Rubens Barrichello would go fifth fastest while BAR's Jenson Button was sixth. Briscoe would improve with a 1m:22.197, good enough for third. After fifteen minutes of the session Michael Schumacher would complete his first quick lap but he could only manage eleventh fastest with a time of 1m:22.749. He would improve to be second on his second
flying lap but was still half a second off Davidson's time, a 1m:22.280.

Jaguar's Mark Webber would put in a quick lap to be fifth, a time of 1m:22.392. BAR's Takuma Sato would come out and with the quickest times in the opening two sectors would storm home with a time of 1m:21.313 to go to the top of the times. He would be challenged by Antonio but, after setting the fastest first sector, would abort his lap. But team-mate Juan Pablo was close to Sato's sector times but would finish his lap in second with a time of
1m:21.419 and move into second.

With thirty minutes of the session remaining Michael Schumacher would come out and with a time of 1m:21.080 move back to the top of the times. As the clock counted down and with twenty minutes left in the session it was still Michael fastest. Team-mate Barrichello was in fourth with a 1m:21.528. The Renault team saw their drivers in eighth and tenth, with Trulli leading Alonso.

BAR's Jenson Button would improve to go second, a time of 1m:21.124. The same went for Antonio who would move into third with a time of 1m:21.264. But for Antonio it would all go wrong when he was to crash heavily at the Parabolica. His car would cross the gravel before hitting the tyre barrier side on, destroying the right rear of the car. The wheel had been torn from the car. Antonio was able to get out of the car and walk away.

With ten minutes left to run Coulthard would improve from sixteenth to ninth. But it would be team-mate Raikkonen, on a high after his win in Belgium, who would blitz everyone with a time of 1m:20.846 to be fastest. Rubens Barrichello was not to let Kimi have it all his own way and the Brazilian would challenge Kimi's time but would just miss going fastest, a time of 1m:20.899.

So with the clock counting down the session would come to an end with Kimi Raikkonen on top of the times, but with the drivers from Ferrari, BAR, and WilliamsF1 all looking very competitive in their times. The times are far closer than in the first practice session.
