Driver quotes:

JJ Lehto (Finland): "Qualifying for us today was as good as it could be. I said this morning that with this heat, we can't go much faster than what Marco and I did in practice today. The biggest thing will be to see what the weather is like tomorrow. If it's cooler, than we can go faster than today."

Marco Werner (Germany): "The temperature today is just too hot for our R8. The Dyson cars are lighter and they had a slight advantage over us today. JJ did a great job, in fact he did the fastest lap of the whole weekend in qualifying. He tried everything but this weekend it was just not enough. If it's cooler tomorrow, we will have a fine race."

Brad Kettler (Technical Director): "Qualifying today was determined by the heat. The R8 is struggling hard in this heat. Tomorrow is supposed to be a cooler day and I think you'll see a different result."
