Abu Dhabi GP FP2 analysis
McLaren say they’ve finally got their Suzuka rear wing working, which was key to Lewis Hamilton’s pace in second practice today.
However Ferrari seemed to suffer a drop-off in performance when running with a higher fuel load at the end of the session.

Lewis Hamilton set the fastest time around Abu Dhabi by Friday evening, and he credited it to the team finally getting a handle the rear wing it has been trying to perfect for four races:
We?óÔé¼Ôäóve been hoping for some time to improve our revised rear wing. It hasn?óÔé¼Ôäót really been working fully since we first tested it at Suzuka, so we?óÔé¼Ôäóve not been able to use it to its fullest extent. We knew that it had potential though ?óÔé¼ÔÇ£ and to have it finally working properly is a huge plus for us.
The car feels good, so I?óÔé¼Ôäóm hopeful for a good qualifying result tomorrow afternoon. Of course, it will be tough, because the Red Bulls tend to pull out half a second in Q3, but our pace is closer to theirs than it?óÔé¼Ôäós ever been.
Of all the weekends this year, this time I feel like we really do have the right package to challenge the fastest cars. I think we can fight for the front row.
It also explains why Button topped the speed trap at 319kph while Hamilton was bang in the middle on 311.5kph – behind all the other championship contenders.
But also remember how quick Hamilton was here last year, topping all three parts of qualifying.
At the time he said he particularly enjoyed hustling his car around the tight sequence of bends at the end of the lap which reminded him of a kart track. In that last part of the lap he was two tenths of a second faster than anyone and almost a whole second up on Button.
As Hamilton pointed out, the Red Bulls (and Ferraris, for that matter), always seem to keep a little pace in hand for qualifying.
The super-soft tyre runs in second practice were also disrupted by a yellow flag caused by Jaime Alguersuari. As we don’t know how many laps each driver had to abort and how much life they had taken out of their tyres, we can’t take these times completely at face value. And there are the usual questions of fuel load and engine life.
Ferrari have got some work to do. Although the car appears to have pace Alonso’s heavy-fuel running at the end of the session gave cause for concern.
If you zoom in on the final ten minutes in the chart above and compare his spread of lap times to the likes of Hamilton’s and Vettel’s you can see Alonso’s lap times increasing a much quicker rate.
At this point Ferrari could have done with Felipe Massa on the track gathering more data, but he was stopped by the side of the road. The radio feed captured him telling the team he’d run out of fuel.
It would be extraordinarily unusual for a team of Ferrari’s calibre to make so basic a mistake as to send a car out without enough fuel in it. And we saw at Spain last year, when Massa was low on fuel at the end of the race, how accurately they can measure fuel use when a car is on the track.
However Cosworth explained some of the peculiar engine difficulties faced at Abu Dhabi which may have caught Ferrari out:
Turn seven is very tight, which can lead to possible issues with engine push into the corner, as well as pick-up out of it.
The engine is usually in full injection cut on the way into the corner, both to save fuel and reduce the amount of engine push, although the latter is a driver preference. A balance must be found to allow the engine speed to drop low enough in full cut to negotiate the turn without the risk of an engine stall.
If the minimum car and engine speed thresholds for full cut are too high, the engine will fire-up mid corner, potentially upsetting the balance of the car. If they are too low, then there is the possibility of an engine stall.
Ferrari ran a different rear wing in FP2 to FP1, and their straight-line speeds increased by almost 5kph as a result
Meanwhile, on the topic of engines, Mark Webber changed his between the two practice sessions.
Finally, the problem of graining reared its head again due to the low-grip surface due to the rain which fell before practice. Bridgestone’s Hirohide Hamashima explained:
Once the dry tyres were used, drivers encountered a very slippery and green surface so we saw a lot of sliding and resultant graining on both front and rear tyres. This graining occurred even when used with low fuel loads on the harder medium compound, showing just how slippery it was.
The track surface improved considerably in the second session, as shown by the quicker lap times. There was much less graining – next to none with the medium compound – however it was still seen on the super soft compound when used with heavier fuel loads.?óÔé¼?Ø
