FP2         1m37.865s (+1.296s)             29 laps                    12th                                         Today we got through a decent amount of satisfactory work, and we duly gathered some more useful info about MP4-28.On a dry track it feels better than it did in Melbourne, but even then its pace still isnt there compared with that of the front-running cars.

Weve identified some further improvements that we can make before tomorrow, though, which is encouraging, and its been a good day in terms of learning.Back at the McLaren Technology Centre in Woking [Surrey, UK] the guys are working as hard as they possibly can to find extra performanceand here in Sepang, too, every single member of our race team is doing a truly awesome job.

Its a lot easier to work on a car thats winning races than it is to work on a car thats not fully competitive, so fair play to everyone for getting their heads down and battling through. SERGIO PEREZMP4-28A-06FP1         1m38.830s (+1.895s)             17 laps                    13thFP2         1m37.838s (+1.269s)             21 laps                    11th

 Today was a very busy day, during which both Jenson and I tried a number of options in an effort to decide which spec to go with tomorrow and Sunday.

Our car has improved since Melbournewhich is quite cheering when you consider that we raced there only four days agoand it felt better in both dry and wet conditions today.Having said that, although as I say it felt better on a dry track today than it did in Melbourne, it would still probably qualify and race a bit better on a wet track than on a dry track, relative to our opposition, so we wont be upset if it rains quite a bit over the next couple of days.MARTIN WHITMARSHTeam principal, Vodafone McLaren MercedesToday we ran through our planned FP1/FP2 programme, successfully applying the upgrades wed developed for this weekend, and continuing our investigative work with a view to improving our understanding of MP4-28.FP1 was dry, but there was quite a bit of rain towards the end of FP2, in which conditions we were reasonably competitive.

Overall, then, its been a satisfactory day, and weve acquired quite a bit more data which well now number-crunch in an effort to optimise our cars spec for the rest of the race weekend.Everyone at Vodafone McLaren Mercedes is working incredibly hard, in very challenging circumstances, and Im both grateful for and impressed by my colleagues indefatigable esprit de corps.
