Hamilton, a three-time winner at Hungaroring, was more upbeat. "We can generally pull out a bit more in qualifying so let's see how tomorrow goes."
Vettel is seeking his first win in Hungary to follow a maiden triumph in Germany in the previous round and all the omens look good for the German star.
