New circuit, new challenge, however as the drivers get more and more familiar with Istanbul park and its unique challenge we can be pretty sure that World Championship hopefuls will be up at the top of the timesheets later today.

However, we believe it's pretty safe to say that you won't be seeing a red car on the first couple of rows, not unless McLaren or Renault have a list minute change of livery.

First out will be David Coulthard, first retirement in Hungary, followed by teammate Christian Klien. The Red Bull duo will be followed by Doornbos, Montoya and Villeneuve.

As we await the start of the session, the air temperature is 29 degrees C, while the track temperature is 41 degrees.

At 13:00 precisely, Coulthard leaves the Red Bull garage, game on.

At the first split the Scot posts 33.648, having run a very fast 'out' lap. At the second split it's 1:05.502 followed by a 1:29.764 at the line, that's 2s slower than he managed this morning.

Next out is DC's teammate, Christian Klien. At the first split the Austrian posts 33.447, he's already 0.2s up on the Scot. At the second split it's 1:04.638, he's 0.8s up on his teammate. At the line the former Jaguar driver posts 1:28.963, maintaining the 0.8s gap.

Robert Doornbos has looked quite good so far this weekend, he's next out. At the first split he posts 35.570, as he locks up into Turn 7. At the second split the Dutch driver posts 1:10.700, he's 6s off the pace. He's really struggling with the car and now we know why, his rear brakes appear to seize and there are flames coming from the back of the car.

All eyes on Juan Pablo Montoya who posts 32.704 at the first split. At the second split the Colombian posts 1:03.560, he's over a second up on Klien. At the line it's 1:27.352, provisional pole for the McLaren driver.

Last out before the break is Jacques Villeneuve. At the first split the Canadian posts 32.979, he's 0.275s down on Montoya. However he goes wide at Turn 8 and though he appears to have kept it under control he loses it and spins out. For reasons known only to himself a flag marshal is waving a green flag. Moments later this is changed to a red flag.

Next out will be Christijan Albers, once Villeneuve's car has been removed from the track.

The Dutchman leaves the Minardi garage, the session is underway again. Like his teammate, he is struggling, however, let's hope that his brakes are OK. At the first split it's 34.682, he's 1.9s down on Montoya. At the second split it's 1:07.015, followed by a 1:32.186 at the line, which puts him fourth.

Felipe Massa is on track in the second Sauber. At the first split the Brazilian posts 33.078, he's 0.374s down on Montoya. At the second split it's 1:04.296, he's 0.736s shy of the Colombian. At the line it's 1:28.419, which puts him second. It's worth noting that his first sector was around 0.1s slower than his teammate.

At the first split Tiago Monteiro posts 33.792, he's already 1.08s off the pace. At the second split it's 1:06.175, he's now 2.6s down. At the line the Portuguese driver posts 1:30.710 to go fifth.
