On average the cars are about a second slower than they were last year basically almost back to 2009 levels, the combination of no EBD + off throttle maps means cars lose more in the low speed stuff. In the mid speed to high speed stuff they've clawed it back almost through better designs but not quite. The only comparison one could make to see who will be fast here, you have to look at tracks with consecutive slow corners such as sector 3 in Spain, and sector 2 in Singapore.
Top 10 best sector 3 times in qualifying for Spain
1 18 Pastor Maldonado 28.321
2 4 Lewis Hamilton 28.340
3 5 Fernando Alonso 28.430
4 1 Sebastian Vettel 28.577
5 15 Sergio Perez 28.608
6 8 Nico Rosberg 28.617
7 10 Romain Grosjean 28.677
8 3 Jenson Button 28.680
9 7 Michael Schumacher 28.713
10 2 Mark Webber 28.714
Top 10 sector 2 times for qualifying in Singapore
1 4 Lewis Hamilton 41.268
2 5 Fernando Alonso 41.391
3 18 Pastor Maldonado 41.408
4 1 Sebastian Vettel 41.427
5 11 Paul di Resta 41.437
6 3 Jenson Button 41.438
7 10 Romain Grosjean 41.643
8 2 Mark Webber 41.720
9 7 Michael Schumacher 41.728
10 15 Sergio Perez 41.790
If this is anything to go by I don't think Vettel will have much of an advantage here in Abu Dhabi for except maybe the final sector, where there are four mid speed corners, two left under the hotel, and two right, with the last corner being especially tricky because it's hard to get the braking point perfect.
edit:
They will not be using the soft and supersoft, and there will be dual DRS zones this year.
"Pirelli will allocate the soft and the medium compounds, which might be a little bit on the conservative side. As in India there are two DRS sections with two detection zones. One of these DRS sections has been extended which should help overtaking."
