Just thinking to myself here.
It’s a consensus that the Ferrari PU this year is equal if not better all round than the Mercedes Lump.
Considering how much time Honda spent abandoning the standard layout and following suit with the split compressor turbo lay out of merc - the standard PU layout seems to be servicing Ferrari just fine! Makes you wonder was Honda right to chase all the R&D for this layout rather than perfect the basic layout of the Ferrari and Renault engine. ..

As Sieper says. It also allows for a much more compact arrangement which has benefits everywhere. It doesn't mean the turbo hanging off the back is a bad layout, but as we edge closer to finding the limits of performance and packaging, id say the Merc/Honda layout would be the one to have.
So in other words are we talking mainly about weight of the piping going to the back where the compressor is vs, weight of having MGU-H shaft in the VEE and compressor at the front with less piping?
The reason I ask is, just based on the amount of PAIN honda had with this full split concept I wonder was the effort worth it.
I'm sure we aren't as aware as the manufacturers of the full range of benefits the layout affords, but there is a lot you can assume from basic principles. Splitting the turbine and compressor brings massive cooling advantages, keeping the hot side away from the cold side. Utilising otherwise empty space in the V by putting the MGU-H there brings packaging advantages. Ferrari/Renault layout forces the turbo out the back, at least on the Renault design, and the turbo intrudes into the gearbox space. Having them split could also potentially allow them to be sized larger with less impact on the overall PU dimensions as well.
The one "advantage" I have seen spoken about the Ferrari/Renault layout, is it allows the PU to be mounted further forward, closer to the driver as the compressor intake is at the back of the PU. The Merc/Honda layout requires the PU to be mounted further rearwards to allow space for the compressor intake which is at the front. Whether that is an advantage or not would require knowledge of the entire car's build philosophy.
The fact the Merc and Honda are the most compact units on the grid has to count for something and they look significantly neater as well.
