Red Bull ran one-two in opening practice for the Hungarian Grand Prix on Friday, with Sebastian Vettel topping the timesheet ahead of team-mate Mark Webber.
Vettel lapped the 4.381km Hungaroring in a time of 1:22.723s to go 0.259s faster than the Australian. Lotus's Kimi Raikkonen was third fastest ahead of Ferrari's Fernando Alonso and the Finn's team-mate Romain Grosjean.
Jenson Button was sixth fastest for McLaren ahead of Force India's Adrian Sutil. Nico Rosberg (Mercedes), Sergio Perez (McLaren) and Pastor Maldonado (Williams) completed the top ten.
Lewis Hamilton was 13th fastest in his Mercedes while Force India's Paul di Resta was 18th. Max Chilton didn't take part in the session after Marussia opted to run reserve Rodolfo Gonzalez instead.
Sweltering temperatures are forecast for Sunday's race and teams got a foretaste of what's to come: thermometers were nudging 30 degrees Celsius by 9am and the track temperature measured 45 degrees by the time the session finished.
Summer heatwave aside, the session was notable as it gave all drivers the chance to run Pirelli's new tyre for the first time.
The tyre, which is being introduced for safety reasons after the blowouts seen at last month's British GP, was tried by some drivers during last week's test at Silverstone but not others.
Vettel, for example, was sampling them for the second time but not Webber. Mercedes, who were forced to miss the Young Driver Test as punishment for conducting their unauthorised tyre test earlier in the season, were also trying them for the first time.
It was little surprise, then, that Rosberg and Hamilton both completed more laps - 28 - than anyone else.
What with the new tyres and temperatures to consider on top of their usual rafts of aero upgrades, teams have plenty to think about this weekend. Yet the dusty track - always more of a problem at the Hungaroring than most other tracks - mitigated against much early running.
When cars did finally go out in earnest, the likes of Raikkonen, Alonso and Webber all featured prominently as did Button and Perez - offering further encouragement, perhaps, to McLaren after both drivers finished in the points at the last race in Germany.
Defending Champion and current leader Vettel was among the last to attempt a time but soon made progress, leaping up from 18th to sixth before moving fastest overall.
From the pitlane, Sky Sports F1's Ted Kravitz reported that Red Bull were trialling a new front wing while Mercedes have a modified rear wing on their W04, plus a 'bulge' under the car's nose.
Williams also have upgrades and Maldonado's time might offer them encouragement. Sauber, meanwhile, ran the Red Bull-style rear end - which features a hole behind each sidepod to divert airflow to the diffuser - they also trialled at Silverstone.
Second practice gets underway at 1pm BST. Temperatures are only going to head one way, so the session will be vital as teams try to get a handle on the levels of tyre degradation ahead of Sunday's race.
