These cars are fast 1:45.4

I suspect Toyota's,BMW's,Sutil,Grosjean & Rosberg went for light last lap runs.
Judging from other teams I think they were doing longer runs testing both tyres i.e Toro Rosso Jaime did a series of laps on the soft tyre(possibly for race evaluation) & Buemi at the end tried them to see the difference but not on a low fuel load.
I expect Mclaren,Toro Rosso,Red Bull,Kimi to be faster in qualifying but it's going to be very tight. Alonso's struggling surprisingly & Webber will have to pray for any chance of getting a good qualifying spot , Brawns not sure where their gonna be so it's going to be fascinating to see how qualifying turns out.
Red Bull & STR need to somehow look at their data quickly and see how they can improve in S1 & S3 because in qualifying it's going to be crucial for their laptimes especially at the bus stop chicane. Their cars seem to lack traction & are slow out of there and thus losing time overall when they cross the line.
