McLaren driver Jenson Button has admitted that the heat expected at Sunday's Hungarian Grand Prix will make it a tough race for everyone.
Button said that while overtaking is usually hard at the Hungaroring, the temperature should see the drivers making mistakes and allowing opportunities for others.
"It's going to be pretty intense tomorrow, which is good," Sky Sports News quotes Button as saying.
"It's not the easiest circuit to overtake on but I have a feeling that if we have a 56 degree circuit temperature, it's not going to be a straightforward race. I think we'll see some overtaking."
Button will start the race on Sunday in 13th position.
