Mercedes AMG F1 W03

[Eruuh]

I don't understand why you guys are calling it an "eed" because the exhaust is pointed upwards at about a 10degree angle.... There is a picture several pages back that shows the exhaust layout without any body work and it's very clear that the exhaust is pointed upwards.

with the air flow coming from the front the exhaust gas is "thrown" down towards the floor of the car

The regulations state it has to do so. The sidepod downwash (air rushing over the sidepods) pushes the exhaust down. Scarbs seems to think the Mclaren (and likely Ferrari too) are able to blow between the diffuser and rear wheels, just to a lesser extent than last year; all due to the downwash over the sidepods interacting with the exhaust.

Mercedes looks to be blowing over the top of the diffuser, and into the little mini diffuser, for some EED action.

guys just quickly..and i know this is absolutely futile since this is only testing....i did a quick Excel comparison between the avarage lap op webber and his long run compared to MS and his....since autosports lapcounts were wrong to say the least. I based this on the laps timed on http://f1tests.co.cc/2012.php?rev=on Now i know the tyres were different and we dont know the fuel loads...but here goes:
Webbers avarage laptime over his 59 Lap stint was 1:28,978s (he started on his lap 29 and stopped on his lap 88)
MS's avarage laptime over his 67 Lap stint was 1:29,865 (he started on his lap 55 and stopped on his lap 122)

all according to the timing site.

By the looks of THIS ALONE the merc seems to be 1,085 sec of the pace of RB...offcourse we dont know the fuel loads...
But lets say webber did indeed have 8 laps less fuel than MS based ONLY ON THEIR DIFFERENCE OF LAPS, we could assume that MS was running with 24kg ( 3kg fuel per lap consumption - BBC) more fuel than Webber. Then, by assuming the deficit of carrying an extra 3kg of fuel around barca from 2011, the BBC commantary team claimed 0,32 sec per 10 kg of fuel at this circuit.

So 24kg of extra fuel should yield about 0,8sec (0,32x24/10) worth of laptime right?
so that leaves about a 0,2/3 sec gap down to whatever.

If we take what autosport saif it might be even less (the gap)


AGAIN, this is based on the assumption that they were both equally sandbagging and that the times they were posting were their ultimate speed....which i guess makes absilutely NO SENSE...since this is testing and we dont know what the hell is going on

If Schumacher averaged 1:29.865....and Webber averaged 1:28.978....where do you get the difference as 1.085 seconds off the pace? I make that 0.887 seconds off the pace.

What the..? Diarrhea Racing?

I think there is a fundamental misconception here over what the aim of blowing a diffuser is.

You do not want to replace the air that would be drawn underneath the car floor with air from an exhaust.

Look at last years diffusers, every exhaust was being used to help seal the diffuser - not blow down the centreline!


You may want to use the exhaust to aid entrainment of air - but that is about the height of it.


The Merc diffuser will definitely not be taking exhaust air into this centreline channel. It will be taking air from under the car into this centreline channel. Same as RBR etc.

[dren]

You most certainly do want to blow the exhaust into the diffuser. For starters you can keep the boundry layer from seperating. The more energy you put into pulling the air out of the diffuser creates more suction along the floor.

By sealing the diffuser along the edge, the teams could run a higher ride height and have a larger virtual diffuser with a lower front wing.

If the rules allowed, teams would blow the exhaust straight into the diffuser like they used to.

On an average I found MSC was about 0.8-0.9s slower which includes the fact that RB was better in tyre degradation something which Mercedes could work on.

But MSC did about 8 Laps extra & that is huge. That is about atleast 0.8-1s slower. I was VERY VERY worried by the times initially thinking Mercedes W03 are in the same boat as W02. But relieved to see them doing so many extra laps.

Maybe saying Mercedes will challenge Red Bull seriously or has similar pace is too much,but they will PROBABLY by fighting for podiums every race & will probably end up ahead of Ferrari & on the level of Mclaren even though I dont feel Mclaren will do well this year.

BTW 127 Laps on a Single Day is fantastic. W03 is a SOLID STEP UP,how big Australia will say

"I'm very happy with the race simulation that we ran this afternoon," said Schumacher.

"It confirmed what we have seen from the first tests with our new car, and that we don't seem to have any big issues with reliability.

"The small things from the last two days I would rate as typical testing issues.

"So from my side, I am happy with our first full testing session, and we have definitely improved our game which is what we wanted to achieve.

"To what extent, we can only see later, but I am finishing with a positive feeling."

yea saw that afterwards...silly calculator that makes it even better then [-o<

You most certainly do want to blow the exhaust into the diffuser.

You want to blow the exhaust along the side of the diffuser. You explained why in your own post.

That flow viz confirms the bodywork burning is from the inside.

If the burning was from the exhaust then we'd see a flow from the exhaust downwards to the burn, instead paint is running roughly horiz across that zone.

Rh front. Might be pickup, lh front takes most of the abuse in Barcelona. Yesterday Nico showed abnormal wear on rears.
In the pic it looks like different camber settings in the front , but depends on where the picture was taken on the track
