Such a beautiful car! I really hope we see the a different Jenson this year..

It is very pretty from that angle - seems to be working straight out of the box too - first time we have seen that for a while.

Ga on the McLaren:

The McLaren still has constant understeer through the corners.

Car is good. Great even. You can still get good odds on Perez. 17/1. if the car's as good as it's starting to look, it's well worth a punt.

Let's have faith in our guys. I posted what GA said, but can he calculate downforce from looking at the cars?

I'm not sure we're even evaluating performance at this stage of the game.

That's right. But it's also important to have performance from the day one.

GA sad MP4-27 isn`t on par with RB8 in pre-season 2012 with lower nosecone, less downforce and other flaws.. and come Melbourne McLaren manage to lockout the front row with some good margin clear of the field.
It`s too early to say anything about the pace of the cars or their strengths as they are in their basic configs. There will be updates, developments ect. and on the final test we could judge the cars and theyr pace.

I wonder if McLaren have fixed the seating issue Perez has? He did seem to be sitting quite high in the car.

Jenson had same issue back in 2010 if i remember rightly he had the issue for 2 seperate test sessions and finally got solved during the final Barcelona test.

Test report :: Jerez day four

Sergio returned to the cockpit for his second day of testing, putting a useful 434km under his belt as he continued to acquaint himself with his new team and car.

Following a similar pattern to the past three days, the day began with some aero correlation work, conducted over a number of shorter runs, before the team turned its attention to mechanical set-up work.

As yesterday, the afternoon was spent carrying out a series of longer runs – with live pitstops – to more fully understand the set-up changes.

Conclusions

Our first test with MP4-28 has been extremely productive: despite a few reliability issues on the opening days, running has largely been trouble-free. Jenson has expressed his initial confidence with the new car, and Checo has played himself in quickly, completing nearly 800km in his first week. He already feels comfortable behind the wheel of a Vodafone McLaren Mercedes.

The Jerez test was a good baseline for the rest of our winter work.

Starting to realise why people like Massa were impressed by the time on Monday, such a time on hard tyres on a relatively green time holds up well.

Good to know the team is happy with the car. If what Jenson said about their correlation with the simulator is true, then we can look positively to the future.

Also, anyone heard any rumors that this car was built using the Toyota wind tunnel?

So do you know why they used the Toyota's instead of their own?

According to pirelli the difference between Soft and Hard compunds is 1 second so with this logic he could do 1.17.8 :)

Most, if it not all the teams have.

Firstly cross reference, as mentioned. Toyota's wind tunnel is used my many many automotive groups so it's calibration is fully up to scratch. Secondly the TMG wind tunnel is IIRC the only automotive wind tunnel which can easily (note, easily!!) use instrumentation such as PIV, and LDV. I know in the past teams have tried to implement such instrumentation in the past but with mixed results. It's not easy and costs a rather large sum of money. A sum of money even an F1 team would not fancy. Toyota's facilities are aerospace spec.

Why spend MORE money maintaining your own instrumentation, aswell as implementing it in the first place (which requires the tunnel to be inoperable) when there is one down the road which is relatively cheaper, and you know the results will be correct.

In the first place it is because the Toyota facility is a much more modern facility where you can do things which cannot be done in McLaren's current facility.
McLaren are building a new wind tunnel for a reason. The current one is outdated.

I read an article some days or weeks ago. Both were using Toyotas Tunnel, but Ferrari had the older one than McLaren as far as I'm aware. McLaren chose this one because their own isn't up to the task anymore and yes it is confirmed that they are working on a new one which will be in the new building (one besides the production centre).

Its more about the instrumentation. RedBull up till 2 years ago IIRC RedBull used a tunnel which was used for testing WW2 missile warheads. One of the most sophisticated wind tunnels in the world, used by Airbus and Boeing was built in the 50's I believe. It's just got updated.

That story about the cologne tunnel was proven to be bogus. Someone stated that one is a 60%, and one is a full scale.

I remember Renault during 2010 flew out to the states in order to use windshear. Amazing facilties.

Yeah McLaren did use the Cologne Toyota wind tunnel as did Ferrari. McLaren are in process of introducing a new one at Woking to replace the current in the MTC. Marussia meanwhile have been using McLaren's under contract. Would expect the new tunnel to include better instrumentation and measurement perhaps a higher scale to suit their road car developments.

Doesn't mean you cannot test a 60% model in a 100% size wind tunnel. I said a larger scale for their road car developments.

From what I understand, the limitations of the Mclaren tunnel are also about the structure/shape.

...and then you've got to factor in that the track was green, and that the Ferrari had had more time to work on set-up.
I think McLaren is quite a bit faster than the Ferrari, so a low 17, with the same fuel level as Massa had, should've been possible I think (guess.)

Yep no doubt about that. When Massa set his fastest lap track was much more rubbered and it was his 3rd day in jerez whereas it was Jenson's first day

There is no way to know it for sure, but let's hope it's true. Only during the Barcelona tests we will have a clearer picture of our competitiveness.

You can eschew a straightline test for a 100% wind tunnel test.
