Well, you can't know it, but there have to be some huge changes to the car, because I suppose that changing front wing does not take 2 hours

According to RMC,new diffusor at Bahrain.
New braking system at Barcelona,drivers are happy now.The team didn't want to change the system but Eric Bouiller forced the team to change the system.

Where is the new FW

That's strange because polish insider from Renault said braking problems are BS. Somebody's lying here.

Or maybe we have misunderstanding and they haven't changed braking pedal settings to Kubica's liking only until Barcelona (which is strange as the problem was known from the very first day of Valencia test).

RF1: And what about today? Well, the sun has come out and it’s warming up nicely. But it has been a slow start to the day as the car had technical issues after the install lap, which had to be fixed. So we’ve been in the garage for almost the entire morning. Now the problem is solved Robert will get on with the set-up programme and try out our new front wing for the first time. So it’s gonna be a busy afternoon.

Nosecone looksthe same. But let's wait for better pictures.

Great to take shot of the front wing from the rear of the car

You can actually see the nosecone?

The Renault F1 R30 could be fitted with a diffuser says ''extreme''if one believes Stephane Samson, a journalist at RMC. It will be available at the Bahrain Grand Prix, with the arrival of the new package expected on the French car.

The broadcaster, however, could create controversy, since according to CMJ, Renault could be summoned by the FIA in two weeks to justify the validity of this element vis-à-vis the Regulation 2010.

Furthermore, still according to French radio, Robert Kubica and Vitaly Petrov has requested a modification of the brake pedal. A change imposed by Eric Boullier, despite the reluctance of engineers on this point, still relied on the preferences of Fernando Alonso.

The major changes are on the plates on the sides of the wing, with a few small plates and huge hole that u can see on the right side of the wing in the front pic and u can see very well in the pic from the back, probably the most complex side plates so far this year in F1(you can judge the complexity of them better on the pic from the back).

Also the upper flap's attachments is higher, as high as it can possibly be.

The most comlex endplates? Bold thesis.

The Renault F1 Team completed its final day of winter testing in Barcelona with Robert Kubica.

Circuit: Barcelona

Length: 4.6 km

Driver: Robert Kubica

Chassis: R30-03

Total Laps: 107 laps

Fastest Lap: 1:23.175

Summary of the day: Dry and sunny weather in Barcelona gave good testing conditions. The team lost some track time in the morning with a technical problem, but covered good mileage in the afternoon.

Robert Kubica: “In the morning we lost a lot of track time with a technical problem. In the afternoon we tried to do a race distance, which was interrupted, but we did cover a lot of laps. Afterwards we just did a couple more runs for set-up work to try and improve the car a bit more.”

Alan Permane, Chief Engineer: “Our final day of testing was a mixed one as we suffered a problem with the gearbox on the installation lap, which limited our running. We managed to get back out at the end of the morning to evaluate some new aero parts and also worked on improving the set-up of the car. For the afternoon we tried to cover a race distance, and although it was interrupted, we did cover the desired number of laps. To end the day we returned to our set-up programme.”

First Grand Prix of 2010
Bahrain 12-14 March

korzeniow, I suppose you didn't understand me properly. I want to win your competition

Interesting that team didn't want to change the brake system but Boullier insisted on it.

Since I've spent the whole day ahead of that Russian live-timing data and here are some nice numbers and graphics:

Kubica's race simulation apparently consisted of 49 laps with stints 18-18-13 respectively, with an average lap-time of 1:25.483.
Hamilton did 61 laps with stints 20-20-21 and an average of 1:24.437.
Schumacher did 56 laps with stints 20-19-17 and an average of 1:25.190.
Sutil did 62 laps with stints 29-18-15 and average of 1:25.876.
While Sutil did his simulation in the morning, the rest did theirs in the afternoon.



Of course it's only testing, we don't really know how much fuel and which tyres everybody run etc etc. But hey, I got bored today and had to do something, hence the 'analysis'. With today's 'competitivenes', Hamilton would win a 66 laps race being 49,7 seconds ahead of Schumacher, 69,0s ahead of Kubica and 95,0s ahead of Sutil.

Mind you, I won't be accepting complaints when things don't go that way in real, so don't bet your house relying on my data

Great work! Two things though:
1) I believe it was Greek live-timing
2) I think Kubica had longer first stint, possibly interrupted by a red flag (note that huge spike on Hamilton's line). As Gemini said the stint lasted about 35 laps, that too would fit your chart. If so, you can't compare Kubica's pace to Hamilton because the latter changed the tyres twice. Once Bob got a fresh set of tyres he was quite close to Hammy again. McLaren is ahead, but certainly not as far as the chart suggests.

On slightly another note, Renault looks faster than Mercedes, which I find very encouraging. That's the planned Top 4 But seriously, both teams are planning to introduce significant updates in Bahrain, while McLaren already mounted some new parts. It's very close between everyone now and will be even closer.
