2010 Winter Testing

[Moanlower]

"Alonso’s 46 lap long run yesterday was interesting. He started out on new tyres with at least 120 kilos of fuel in the car and was quick initially, with a lap in the 1m 23s, then the pace dropped off for a few laps, but then the final part of the run was very fast. His final lap was 1.9 secs faster than his first but he had burned off 120 kilos of fuel worth around 3 seconds par lap.

Schumacher did a 32 lap run on a new set of the same tyres, which started out in the low 1m25s and came down through the 1m 24s steadily. His final lap was 1.9 secs faster than his first. So he had burned off approximately 80 kilos of fuel, which is worth around 2.4 seconds per lap."

What does this tell us? (im a bit confused as to what you can take from it)

basically it means that the pace of the Ferrari was higher true the entire stint than the Merc, with fuel on board of at least 120kg which costs him approximately 3seconds per lap compared to the Merc with approx. fuel weight of 80kg which costs about 2.4sec per lap. In theorie the Merc could've been a bit heavier but I doubt it, and if so it would've been by a small margin.

So working on the fuel for them runs was expected the Ferrari and Merc were virtually the same pace, with the Ferrari just edging it?

I found it interesting that MS did not bother coming out near the end. He could easily have gone and improved his time but was more than happy to finish 5th (or whatever it was). He seems to be focusing on testing and testing alone, unlike others who either go for that headline time or messing abouta bit (FA messing with JB the other test).

Going for fastest lap in quali trim during testing isn't really necesarry atm, unless you need sponsors or have doubts about the car's speed. What Alonso did with Button or Lewis with Schumi is not all about playing mind games. It's also very important to know how your car behave when slipstreaming a Mclaren with such a big a new design of diffuser.

Next week will be interesting since most of the teams will have their updates to start the season with and will do more quali runs since there's nothing more to hide so close to the start.

Maybe the Merc wasn't capable of posting the quickest time? I doubt that they didn't run on fumes at one point or another and just went all out. And IIRC, some teams including Merc ran the cars until they were empty and stopped on track.

I would think that at one point or another you have to make qualy runs to prove to yourself that you have the outright speed. Especially as you makes changes to the car's setup and parts.

Besides, posting the quickest time is more than likely a moral booster for the entire team.

If the weather holds there is no doubt we'll see the fastest times yet from Jerez, however that's just a factor of the track conditions...but fastest lap order doesn't mean much still.

We really won't know until the final Barca session and/or Qualifying at Bahrain.

Ferrari changed to their third engine (I think?) last night, so fresh one today:

It's time to change the engine of the F10 for a fresher unit. The second one used so far since the Valencia test did a great job once again.

Best conditions so far as they are heading into the lunch break. Virgin still in hydraulic trouble? Glock only did 8 laps.

No real testing until Barcelona for Virgin:

"The hydraulic issue caught us out on the first day of this test and since Wednesday we've been forced to run conservatively until a new solution is available for the Barcelona test. We'll try and put some more fixes in place tonight to allow us to get some more laps in tomorrow. We're very aware that Lucas has had very little running so far and we hope to improve things so he can get more seat time at the Barcelona test next week."

Thanks, but I strongly doubt that all cars are at the exact same scale though.

Just enlarge that pic to a scale that a tyre just fits your screen, brighten it up a bit and then just compare the size of the tyres.

Video with questionable pit-stop at 1:50

What a loooong pit stop. I nearly fell asleep...

By the way, I was sure the number of people during a pit stop would drastically reduced, but they are still 3 per tyre... Someone else eared about that (maybe for 2011 or 2012) or did I dream ?

[ESPImperium]

Im starting to get a little worried about the lack of distance that Virgin has covered in comparison to Lotus. They need to get that car with arround 100 laps on the clock one day, otherwise they arnt gonna get too far in the development race.

They have had twice the time to design and build their car than Lotus, and one more test, and altho the times (whitch i dont read much into anyways) dont say that the Lotus is faster, it certainly is looking like the car with the stronger baseline so far.

Im worried for that cars relyability rate.

Record track temp of 30°C today. It should be the fastest test day. Somone will probably attack Button's time soon.

Matching the size of the tyres is the wrong way to do it, unless you are absolutely sure the camera is aligned and focus on that point. I don't know why people started doing that in the first place.

To match the pictures you have to know where the camera is focusing on. And from that point you scale a part of a known dimension, that is perpendicular to the camera view AND either Horizontal or Vertical.

For example if I know the camera is focusing on a wheel and the wheel face is perpendicular to the view of the camera. I can choose to scale from that point. Then there is the problem of perspective. If the person who is scaling the pictures know how objects appear when viewd in perspective (as compared to isometric or orthographic) , he can use drafting methods to obtain the centre line of the car and measure from there.

I would do it in a 3d program that has "perspective" view: Make four cylinders to represent the tyres. Make the cylinders the same diameter as the real tyres. Draw a line going through the centres of the rear tyres and do it for the front. You know the max width from tyre to tyre. Draw the horizntal centre line of the car on the midpoint of the "axle" lines. What I would then do is to import a picture of the car into the 3d view then adjust it (move, rotate, scale etc) so that it is coincident with the wheel that the camera was focusing on. Then knowing what type of camera was used (like wide angle, foucs type(?) etc I don't know much about cameras lol) You set the perspective camera view to match that camera. Then the tyres in the picture should somewhat match up with the cylinders that we just drew. Then all we do know is adjust the centre horizontal line until it reaches the tip of the nose and the back of the crash structure. This is the true length of the car. Similarly you can do it other points on the car such as to find the wheel base. You can do it for the height of the car too because we know the maximum height.

Nico Hülkenberg causes a red flag.
