Most likely the drivers couldn't see sod all out of them (the mirror glass was odd) so the minimal difference they make wasn't worth the drivers being uncomfortable. Ferrari dropped theirs from last season too.

 

That would be very amateur-ish from Merc (or any F1 team for that matter) to design a rear-view mirror which doesn't fulfil its primary objective...

 

From photos released to date, it sounds like Merc has 2 different rear wing endplate configurations. Unclear whether any of those two is new.

 

EDIT: BTW, is it time to start the second thread? Thought the page limit was 80?

Not really, it's pushing boundaries. Like I say, it's a marginal gain, but one that's obviously only worth taking if it doesn't hinder the drivers more than its gaining you in slightly decreased drag. Only way you can see if the drivers like it is to mount it to the car and let them try it out.

Given they have a sizeable advantage over the competition it's hardly worth risking the drivers crashing out for a tiny amount of lap time gain. Perhaps if the competition was neck and neck/ahead they'd tell them to live with it.

If true, shouldn’t the ‘effect’ be banned instead of the way you achieve it? Looks like another trick suspension to me.

Can you clarify just what it is that you want to ban?
Can you also clarify what exactly it is that you think Mercedes has done which is illegal to warrant the ban.

Thank you.

It's not a trick suspension, it's a beast of a chassis with loads of downforce combined with the most efficient engine treating the tyres better than everyone else, but that doesn't sell so F1analis needs to invent some trick.

It's been known for a while that Mercedes has been running such a set-up and it's not just them, Renault, Alfa Romeo and I think Toro Rosso also run a similar layout.

Banning the 'effect' of something.... that would open a huge can of worms up and down the grid. No, they could just reword the rules, but I'm not sure you could guarantee only hobbling Merc, so may not have the desired goal of helping the others get closer (although I know memories are short but Ferrari had race winning pace in Bahrain and pole winning pace in Baku).

Suspension enhancing aerodynamic performance, Mercedes are the true pioneers on this, since 2017(?) In a way I agree with P123 that trying to ban ‘effects’ would be opening a can of worms. But, well, yeah, it’s still kind of a trick if it works. Guess it’s all about exploiting the limits of the regulations.

The notion that Mercedes have spend "about the same" as the other big teams is a bit of a peep into the future world of budget caps if you ask me. They've only "spend the same" as Ferrari and RB based on figures offered, for which there is no obligation and certainly no forensics into corporate structures and expenditures. I'm quite certain that Mercedes total engine development costs dwarf the kinds of numbers banded about. Comparing their total spending to RBR over the hybrid era is hilarious considering RBR have only had a works engine for a matter of months and could not afford to build their own. The only other team remotely in the same postcode is Ferrari and they've enjoyed huge additional subsidy in the Hybrid era. I'm quite sure that Mercedes have spent the most in the hybrid era and they are dominating it, followed by Ferrari, followed by RBR. So yeah, Mercedes performance is incredibly impressive, almost faultless these days, but the facts are the championship table runs in total budget order. I wouldn't say many other teams are underperforming within their budgets.


Just because Mercedes have been better is not enough for you to draw the conclusion that they have spent more than everybody. There's absolutely no evidence of that.
But bringing in the right people, some of whom were sacked (Aldo Costa for instance) and create the conditions for them to perform at their best is probably their greatest achievement.

Makes sense, Greta enabled the kids a free friday from school, while Lewis is wasting their sunday :p

AFAIK people at Daimler have more of an issue with it that there is no German driver, the whole debate about enviromental waste is a external minority opinion and mostly shared by those who are not aware that Dailmer actually isnt spending that much own capital.

Few friday funded by Soros....

This comment doesn't make a lot of sense when you consider that most of the performance advantage comes from the low speed stuff where the aero effect is the least. 

 

Traditionally a car unloads itself on the inside tires due to weight transfer in the corners.  This is what limits the maximum corner speed (on top of the downforce).  If you can use the suspension to push down on the inside tire, you keep load on the front inside tire during trail braking and at apex, meaning you can go faster. 

 

It's obvious on the front axle, that if you make a geometry, and just boost up the power steering, you can load the inside tire in a corner without straining the driver anymore than usual.

 

If you have managed to replicate this effect on the rear axle (where the everything is passive), you could also improve the corner exit traction on the inside wheel as well. But would require very clever implementation.

 

I don't know what Mercedes are actually doing. But it's a possibility that its'a combination of many many things including aero, and suspension.  Overall they have a great car.

Mercedes have tyre warm-up issues, so it's Ferrari's race to lose.

Are you serious?

 

It could make Q3 a bit of a lottery, but I presume Merc would probably go for 2 warm-up laps, 1 fast lap... given how short the lap is, it would be easily feasible around Monaco.

If in 2014-2016 Mercedes was clearly ahead of everybody else with their engine, this 2019 domination is coming out of nowhere. And they seem to run great on every track. They must have found a trick somewhere and no one knows about it.

No I wasn't being serious kernel, but I was tempted to post that in the Ferrari thread. :D

Suspensions normally move on bumps or kerbs, not in the corners. Look at any Monaco onboard, I haven't seen any other car do that this year or in the previous years.

It looks different if you compare it:

 

https://www.youtube....h2JXolPVI#t=37s thats a lap from 2018, it's clearly moving a lot more in 2019.

Looks like a variation on a theme to me - Merc are using a ball-joint rather than some sort of king-pin used by the other teams. I don't see how you can get away with a single joint with the push/pull rod, because the packaging and positioning means that the loci of the rod isn't constrained to a single, shared reference plane.

That's not true at all - roll on the body is induced as additional lateral force is generated by the tries from below the car's CoG. Unless the suspension is rock-hard and doesn't move at all )which defeats the whole purpose of suspension), it will move because of roll and weight transfer caused by a change in lateral acceleration.

Interesting video, looks to me like they run quite a bit of negative caster, which makes the inside wheel go up the more lock you put on. It's exaggerated by the full lock hairpin.

The movement of the suspension is directly related to the amount of steering input. At full lock, it reaches the maximum range of suspension travel. It's something all cars probably do, but to a less noticeable extent. I can't tell if it's just more visible because of the high mounting of the Merc suspension arms, or due to their exaggerated use of the suspension trick. I assume scrutineers check every race weekend, so it's probably legal. Looks more than the 5mm maximum range of motion prescribed in the regs, but that's a static test, and in motion, things might be different.

Exactly  :up:  Aldo was a key fish that John West rejects, yet Mercedes snapped him up and turned out a 3 Michelin star dish.
