2023 Mercedes-AMG | Petronas F1 Team

[Stu]

This is the AMG Petronas 2023 Team thread; trying to turn it into an individual glorification/vilification thread will render it outside of forum protocols.

Sundry posts that relate to This Driver/That Driver and Adrian Newey have been deleted (two whole pages worth!)

How was Schumacher an exception? We had no social media back then and the media was definitely less. We don't know that part for sure...

I'd love to live without social media, lucky Schumacher I'd say

Could we make some conclusions from this video regarding W14 vs. RB19 floor?

Then, regarding the cause of RUS` PU failure, one former RB engineer (known as EngineMode11 on YouTube) said on a podcast with Blake, another former RB engineer (and YouTuber known as BrrrakeF1) speculated that it could be a turbo-related failure:

(37:51 minute) :

So, did the team reveal what the real cause of failure was?

Both floors look similar behaviour. RedBull just seems to rise up first (due to the slope of the road) then Mercedes follows shortly after.. If you want to split hairs maybe you could say the Mercedes has a slighlty lower ride height at that slow speed.

Turbo failure has prominent sound when failing. WAtching Russell's onboard, there is no such a sound, it sounds like he just had a loss of power.

The floor entries though, look different.

All manufacturers at the limit

The season is only three races old, but the FIA has already had to issue grid penalties for using too many engine parts. Ferrari is not the only one with problems. Even the normally bulletproof Mercedes engines have suffered capital damage. The manufacturers are alarmed.

Even Mercedes is struggling with problems. McLaren driver Lando Norris has already lost an engine irretrievably. In Bahrain, a malfunctioning pneumatic valve system destroyed the six-cylinder turbo.
The Englishman needed a fresh set of combustion engine, turbo, MGU-H, MGU-K and exhaust for the second Grand Prix in Saudi Arabia. It is already clear that Norris will hardly get through the season without a penalty.

Mercedes driver George Russell suffered a major engine failure in Australia. The exact cause is still being feverishly sought at Brixworth in England. Before the race in Melbourne, Mercedes had the exhaust replaced on its own cars and those of its customers Aston Martin, McLaren and Williams.

Safety concerns were cited as the reason after there was damage to the exhaust system on Lance Stroll's Aston Martin in Jeddah. At the same time, this meant that the hot electric MGU-H engine was no longer recuperating. Stroll can count himself lucky that his power unit didn't get shot in the process.

Exhaust is a PU supplier part?

Exhaust is a PU supplier part?

Ahead of the exhaust turbine? Yes. Behind the exhaust turbine is not inside the PU supply perimeter so in theory there could be variations.

I see. I'm asking because there were reports Stroll's exhaust problem was actually caused by something else on the car, which in turn caused all other problems. Kinda like that gearbox nut working itself loose on verstappen RB causing driveshaft failure.

[PlatinumZealot]

Exhaust is a PU supplier part?

Yes. And even with that, variations in exhaust runner layout not encouraged by manufacturer for easier preformance, reliabilty and quality management.

I beleive few years ago Renault allowed Redbull to have different exhaust runners.

Mercedes I think had a small variation on Force the India once? But not much than that.

It may have been permitted previously but they changed it for the new engine rules. For the 2022+, The exhaust "runner" is a homologated part. There are no variations. 1 part that Mercedes declared for all PUs.

F1 | Mercedes: A cylinder had blown in Russell's engine

The Brixworth technicians have identified the break that stopped the English rider during the Australian GP.
George will have in Baku certainly a new internal combustion engine and it has not been decided whether he will also
install a fresh hybrid system. The Stella engineers have not yet identified the cause that led to the withdrawal
and there is some concern about the reliability of the 6-cylinder.

I said at the time it would be a dropped cylinder.

Probably carnage in there and working out what went wrong first in order to prevent any further issues
