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.

Incredible opportunity to see some critical areas of the car up close.
btw: what are brake bypass ducts and why are they used in fp3?

Yeah that was an awesome video zibby. We got a look at the sidepod rad (partially covered) which may have a slight curvature to it, as well as the uninstalled floor (around the bib/tea-tray) and a clean shot of the steering wheel during clutch bite point check. That car is something else!

I was also surprise at the number of exposed boxes there are in the cockpit (when Lewis was being strapped in).
That struck me as well. Would love it if all the teams did this.

They use them all the time, it`s just an air duct that goes over the brake disc into the cake tin which needs checking to make sure it`s clear of debris. Some air is vented onto the disc to help cool it and also blow the warmer air onto the rim to help with tyre temperature.
Later on they show it back in place, then later with the cake tin back on covering it. These ducts can only protrude so much above the wheel center line and Merc and Racing Point got pulled for it earlier in the season for having an intake duct to high!

The bypass duct does as its name implies. It ducts air around the brake and directly outwards through the wheel. It replicates the old blown axle.

This was already used even with the blown axle. Teams want as much outwash as possible from the rim

Hmmm seems like the bypass duct introduces cooler air into the wheel outwash. The brake tins probably introduce hot air. Maybe the Mercedes needs temp difference for their brake ducts to work. Probably why they're not as dominant when the ambient temp is high.
The height of cultivation is really nothing special. It is merely simplicity; the ability to express the utmost with the minimum. Mr.Lee

Would someone post pictures of the two bodywork configurations Valtteri and Lewis trialed in FP1 please?

Which one do you guys think is the higher cooling spec anyway? BOT's car had the bloated bodywork around and behind the exhaust manifold area, but with clearly smaller and narrower (making it technically a more "pinched in" bodywork) rear outlets compared to HAM's config, who had what has been the "relatively high" cooling setup ever since they introduced their 2019 Germany upgrade package...

I'll see what I can find. In the meantime, here's the wheel:

One thing I have picked up on in looking for the requested photos, is that both cars appeared to run the “old” FW spec that had the split tip on the flap just below the uppermost flap.

I think both cars were running the Bottas solution during FP3, definitely Hamilton but I'm not 100% sure on Bottas' car.

Is Mercedes' front-wing upper flap split or is it just the reflection?

Reflection. Only the flap under the uppermost flap has the split-tip.
