Mercedes AMG F1 W04

[Ferraripilot]

Huntresa is right! They are doing this to clear up flow to the SMH (Starter Motor Hole)...it is similar to what ferrari were doing on the F2012...but they have taken it a step further with the F138...

This is done to help prevent stalling of the diffuser by allowing clearer flow through the SMH

Yes, only F138s apex where the bodywork meets the floor has flow impeded by the pullrod pickup point essentially mounted directly in the way. W04 has the lower a-arm mounted behind the pullrod and higher (pullrod too) thus impeding floor flow less.

About the passive DRS...
On Friday we saw that they tested a passive DRS, do they? What do you think? We will see a passive double DRS on W04 in Australia?

[Mika1]

Maybe, maybe not. Depends on how good the system works.

[PlatinumZealot]

That dip in the floor is pretty standard. You are only seeing it more clearly now because the cars have smaller gearboxes.

Gary Anderson said that W04 has understeer in the entry of the corner, and than the rear snaps leaving the corner. What means "snap"? It's unstable or is fixed very well? (I'm not speaking english perfectly and about the using of "snap" i found different contexts. Look: "Mercedes has understeer on entry than rear snappy,"

P.S I know that the forum is for details about the car, but it's related to the car, I posted here because here is much more discussion. don't criticize me to harsh

It usually means the car lacks downforce and grip.

[tathan]

he's saying the rear loses grip suddenly

I do think that is a totally false statement.

Snap= sudden, not progressional.

From what I know, that's usually more setup related than inherent to the car.

[Ra8]

Understeer into the corner and than oversteer leaving the corner... just the opposite what you generally want.

Not necessary. That was one of the biggest problems on last years Ferrari and it was so bad that was practically undrivable.

[wesley123]

I'd say the sudden 'snap' is something mechanical. Why? The exhaust is blowing since the driver is on throttle. So the rear downforce is generated, in comparable amounts as on corner entry when the mapping takes care of that. So therefore I think it is either a setup 'problem', or a mechanical issue.

If it was aerodynamics I am sure a similar situation would have occured under braking and corner entry.

[wunderkind]

First of all, I don't think the W04's backend ever 'snapped' out totally spinning the car during the entire Jerez test. I think what Gary Anderson meant was the backend of the car snapped(as in oversteered) coming out of the corner requiring the driver to put in some hefty opposite lock to correct the car. Providing there is no mechanical problems on the car, the problem is most probably grip related. The W04 seems to have less downforce than the McLaren, Red Bull, and the Lotus. That meant the W04 has a narrower performance plateau and Hamilton and Rosberg were dancing on and off that narrow plateau going in and out of the corners. The cure is more downforce, lots more!

There is a hole at the end of the beam wing, and the beam wing looks fat in the middle, like there is something like a channel, wich leads to the end. Do you think they use some kind of passive DRD to stall the beam wing.?

They were testing the DRD for half a day. I really find that diff very unique?

[wrcsti]

it looks like the same slotting done on the tips of the rear wing. If there was a hole and channel no light wouls shine through
