Mercedes W11

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

Yet another post on that rear suspension..
See the rearward arm of the lower wishbone being angled backwards instead of being at a right angle to the crash structure and parallel to the driveshaft like the upper wishbone.

Also with the mushroom suspension, it was so (at least acknowledged as the likely reason) that the mushroom suspension would be as far backward. But I do think Mercedes looked at that, and started thinking about different ways to use that kinematically (and maybe not so far back/extreme as McLaren, whose suspension seemed limited and a bit fragile from it); might well be that it has been an idea someone played around with in their heads until they could apply it for this years car.

The mushroom suspension was basically two "blockers" that made "dirty downforce". They used it like an air dam to creat low pressure behind the diffuser. The track rod and lower control arm were used. McLaren abandoned the design after a time.
Mercedes design seems to be the opposite: get the suspension out of the way to increase efficiency by allowing more flow through the coke bottle area. You can utilize the air better with the, diffuser flaps, brakeducts and the RW end plates if you have more avaialable energy in this area.

It seems likely that Bottas' wheel has a button or paddle just behind the top of the left shoulder. Does anyone know what that button/paddle is? Or have any pictures of the 2020 wheels (I believe Merc generally run 3 over a weekend, for each of their drivers)?

Interesting article about Mercedes engine 2020

https://www.formulapassion.it/manifesto ... 8.html/amp

Really strange the focus on higher rpm considering that at 10.500 the fuel flow is limited... probably some tricks, but well, it is MB (not Ferrari) so no need for FIA to do an investigation... it is always all legal like tyre test, wheels, suspension ducts, DAS, etc :roll:

There was a merc podcast where they mentioned peak power was somewhere between 10,500 and 11,000 rpm so I don’t think the fuel flow limit maxing out at 10,500 dictates where peak power can be, or maybe better said, where they may want it to be given the peak operation considerations of other PU systems.

During one of the practice sessions and also on Lewis' qualifying lap, I noticed a few of occasions where the car while at the exit phase of a corner (increasing throttle application), would vibrate and sound as if it had run over a typical serrated kerb.

It can be see and heard in the following video at 0:22, 0:35 and 1:00. I would if it has anything to do with tyre pressures?:

A few years ago at Spa, I think 2017, the Merc was breaking traction under acceleration out of the “bus stop”. My memory is that it was oscillating in roll mainly due to underdamped deflections of the tyres.
