Reigning world champion Sebastian Vettel set the fastest time during second practice for the Abu Dhabi Grand Prix.
Vettel’s time of 1:41.335 was a tenth of a second faster than team-mate Mark Webber.
“It’s difficult to say today how we compare to the others, we know the Lotus is quick here, but we also had decent pace today,” he said.
“It’s not always so easy at this circuit with the conditions changing throughout the day; we start in the sun and finish at night and the track temperature changes during that time. But, no big issues, so I’m pretty happy.”
“The second session today was more representative of the race and qualifying than the first, due to the time of day and temperatures,” added Webber.
“It was a lot about the tyres today; I think the soft tyre will hold out better here than it did last week. It wasn’t a bad feeling for the first day, we got the information we needed, so let’s see how we get on tomorrow.”
Lewis Hamilton was third, with Kimi Raikkonen in fourth and Nico Rosberg in fifth. The German believes that Red Bull will be difficult to beat.
“Our aim is to be the best of the rest again which I’m quite confident we can achieve and score some important points,” he said.
Sergio Perez headed McLaren team-mate Jenson Button in sixth place, while Fernando Alonso managed only the eighth quickest time. The Spaniard fears that Ferrari is in for a tough weekend.
“Hopefully there is more in the car. We are in a position that’s not normal for us. We are struggling a little bit more this weekend, but to be fighting for Q3 is not good enough for Ferrari,” he said.
Nico Hulkenberg and Felipe Massa rounded out the top 10.
Esteban Gutierrez was 11th, ahead of Romain Grosjean, who topped the first session but suffered a brake problem in the second session.
“It’s been a pretty good day even if we missed time in the later session whilst the brakes were worked on. We also had a little vibration that needed looking at, but it wasn’t the end of the world. The car feels pretty good,” he said.
Paul di Resta was 13th, ahead of Pastor Maldonado, Adrian Sutil, Daniel Ricciardo and Jean-Eric Vergne.
Valtteri Bottas was 18th, ahead of Giedo van der Garde, Jules Bianchi, Charles Pic and Max Chilton.
