P1 programme 14 laps 1m34.483s (13th)
Lewis's first session was devoted to understanding and evaluating new aerodynamic components for MP4-24 - principally a substantially revised floor section and matching top body. With modifications to the car carrying on into the first session, and with the morning's running briefly interrupted by a rain shower, Lewis completed just two runs (five laps/1m34.483s and four laps/1m35.945s) and ended P1 in 13th position.
"The car still lacks downforce," said Lewis afterwards, "but there's definitely been an improvement from the new parts we tried today."
P2 programme 23 laps 1m32.149s (1st)
More spots of rain delayed the start of Lewis's afternoon programme, but he still completed three runs, this time with the added benefit of the new FW5 front wing, recording runs of eight laps/1m33.059s (Primes), four laps/1m32.413s (Options) and three laps/1m32.149s (Options).
The engineers used this session to back-to-back the new front wing against the older iteration while also refining the balance of the new package over long runs.
Lewis said: "We've still got a long way to go but, most importantly, these new upgrades are pushing us in the right direction. It's a work in progress, but the guys back at the factory have done an incredible job to get these parts to the circuit - I've even heard of one guy working a 36-hour non-stop shift to build these parts, which is incredible. Hopefully we'll now do our job at the track and try to keep everything moving forward. It's still early days, and we shouldn't get ahead of ourselves, but I'm hopeful of being able to get into Q3 tomorrow and look at scoring a couple of points on Sunday afternoon."

"An encouraging afternoon for Lewis, who used the full new aerodynamic package for P2. Although it is still early days, and I'm sure we've yet to see the strongest efforts from Red Bull Racing and Brawn GP, I think there are good signs of an improvement. It was a more difficult day for Heikki, who regrettably didn't have the new aerodynamic package upgrade, encountered traffic on his laps and generally had a much tougher afternoon. But he is a fighter, and I'm sure he'll have a strong weekend nonetheless."

"This looked quite encouraging, I have to say, and definitely better than I'd anticipated before the sessions today. We certainly did not post ‘show times' four our home race; our speed was genuine and quite a bit better than in the last races. I certainly don't expect us to be fastest tomorrow, but if everything comes together we probably will be in a position to deliver a solid job on race day. Heikki's car today was not on the same technical level as Lewis's, which had new pieces that only arrived last night and which are not yet available in sufficient numbers. Our KERS hybrid is a good help around this circuit and gives us more than three tenths of a second per lap."
