McLaren and Ferrari will continue using KERS in the European Grand Prix.
Both Renault and BMW have dropped its use for the rest of the year.
Hamilton expects KERS to give him a good boost off the start line allowing him to gain about 15 meters into turn one.
In qualifying a KERS boost out of the final corner before the start of the timed lap and additional boosts out of the four second gear corners during the timed lap should give Hamilton a significant advantage of up to 0.3 seconds in the dash to qualify well on Saturday.
The layout of the Valencia circuit makes it very difficult to overtake and we would normally expect a procession for the duration of the race, but hopefully the odd KERS boost during the race will allow the drivers to leap frog the slower trains that get established.
The Valencia circuit is well suited for the cars to use KERS because of the large number of suitable breaking points where the charging rate can be set low so as to reduce the destabilizing effect of the KERS recharging kicking in.
McLaren are back on top after having their hopes dashed a couple of weeks ago by a puncture in Germany.
After the lottery of qualifying with the rain during Q2 in Germany it was easy to speculate that McLaren were back with a competitive car. However, any hopes of the podium finish that we all anticipated were dashed when Hamilton had a touch which caused a puncture while pulling into a KERS assisted lead at the first corner.
We had to wait another two weeks before Hamilton was able to show what the new car was really capable of around the Hungaroring.
Hamilton did not put a foot wrong the whole weekend.
Q1 was nearly half way through the 20 minute session before he completed his first flying lap in 1:21.791 which put him into second behind Raikkonen. About twenty seconds later Vettel, and then Webber posted identical times of 1:21.590 on each of their second flying laps. Another fast lap by Hamilton and then back into the pits leaves him dropping down to sixth and eventually eighth before changing his tyres and having another go.
Q3 saw him 4th on the grid behind Alonso, Vettel and Webber.
The race was perfectly driven. A place was gained at the start, then he got passed Webber after 11 laps and then led the race to the end.
Well done Lewis.
The long awaited McLaren aero updates have finally arrived in time for the German Grand Prix at the Nurburgring and are certainly making a difference.
Lewis Hamilton started trying out the new “bits” in P1 doing only 14 laps, far fewer than most of the other drivers.
A couple of settling in laps (out and back into the pits) at the beginning of the practice three session allowed Hamilton to try out the latest McLaren aero body parts flown in overnight.
Lewis Hamilton then went out again after about 15 minutes, and then started doing quick laps. On his sixth lap of the session, following a few warm-up laps, he started doing fasted sectors for sector one, then sector two and finally sector three to put in a fastest overall time of 1:32.331. The next lap was faster still at 1:31.965, then he took another break and stayed on top till his next outing.
After a quick out lap Lewis immediately put in a fast one, again doing three fastest sectors of the day, to drop the time by nearly three quarters of a second down to 1:31.252. He then took a breather on the next lap winding up for another quickest of the day of 1:31.121 on the very next lap.
It was then back into the pits and back to working on collecting information, with the knowledge that he now has a competitive car for the German Grand Prix, following the furious development work that has been going on back at the factory.
Keikki Kovalainen ended the session 17th without the benefit of the new aero package. The one and a half second difference is probably not all down to the aero package, as he was probably running with more fuel etc. so as to collect data ready for qualifying later today.
Silverstone with its fast straights would seem to be an ideal track for KERS to provide a slingshot out of the corners to gain a few Miles per Hour for the full length of the straight.
The BMW and Renault teams are not so sure and have opted not to use KERS at Silverstone.
Ferrari has continued its development of KERS and now has a new lighter version which will be used by both Massa and Raikkonen.
McLaren will be trying out both options on Friday with Kovalainen running with KERS and Hamilton seeing how the car goes without it during practice one and practice two. There are not many hard braking areas where the KERS can be effectively recharged.
Following months of dispute about the format for the 2010 F1 series the Formula One Teams Association (FOTA) have decided that they have no option other than to form a breakaway series.
The teams will most likely be joined by Lola and Prodrive who were surprisingly not included in the FIA preferred new entrants for the 2010 F1 series. The full line up will be Brawn, Ferrari, McLaren, Red Bull, Toro Rosso, BMW, Renault, Toyota, Lola and Prodrive.
The FIA say that Ferrari are contracted to F1 for 2010, but Ferrari says that their contract with the FIA has been broken due to the FIA ignoring their right to veto the changes proposed.
Red Bull and Toro Rosso are also in a similar position to Ferrari, with the FIA threatening to sue.
So as it stands F1 will include Williams and Force India, who broke away from FOTA due to their own contractual obligations, plus Team US F1, Manor F1 and Campos Racing.
I cannot imagine a proper F1 series without Ferrari so it will be interesting to see how things work out in the next few weeks.
