Mercedes Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

What is going on with that exhaust piping? Octopus turbine housing?

That exhaust piping arrangement is related to merc side pod-less design

Still looks like more than one entry into the turbine housing.

I think it's more related to having the bodywork undercut the ICE.

One of the pipes looks like it turns towards to the engine when it is going towards to backside. Isn't this brakes/slow down exhausting pressure?

Yeah..the lowest pipe has an extreme curve, and i think there is no other option becos pipe length and diameter must equally same.The rear Merc bodywork also one of the slimmest,simply not much space left
:D :lol: Funnily after looking the PU for quite some time,,i think the PU look doomed since it doesn't result into distinctive power advantage OR contributing pace with Merc sidepod less design approach,,except slimmer rear bodywork

I actually spoke of this back when the W11 was released as one of the developments I'd like to see from Mercedes' HPP department. Essentially using the gearbox casing volume (or close to it) as avenue to equalise the exhaust manifold length. viewtopic.php?p=884723#p884723

The twin charge pipes have me confused!
Wait. I see it now. It forks at below the compressor.

Look at the centerline of the compressor to where the top of the gold foil part is. It's either the compressor has a diameter of large pizza, or the discharge pipe does an half-a-loop around the compressor before going out to the charge coolers.

Smart! They have shifted the "basket of snakes" of the exhaust from beside the engine banks, and packaged it to the rear of the engine to better narrow the frontal area of the PU. Talk about junk in the trunk.

The gold and black tubes are quite fine. They seem to go to their own intercoolers under the fuel tank undercut. Im interested as to why the pipes are so small. Maybe for high velocity?
For Sure!!

The 2022 Merc compressor exit is probably going upwards because I guess it has been designed for a water-air intecooler placed above the compressor, like the Renault. But unlike Mercedes, AM and Williams, Mclaren is still using twin air-air intercoolers, which explains the look of those compressor to intercooler pipes. Yes the first pipe does half a loop then splits in 2 and the right hand pipe turns back and passes below the compressor... (a bit like Honda before they used a twin outlet compressor)

The MCL doesn't really have an undercut around its fuel tank like most cars.

The strange intercooling system of Mercedes seems to have a conical/funnel shape.

That is a truly hideous design by Mclaren.
