In response to the lively discussion about the W-220’s predecessor, I have posted this little gallery of how one might go about redesigning the rear end.
The initial problem is the narrow boot aperture and the odd business of the visible weld in the middle of what looks like one part.
I can see from Daniel Callaghan’s proposal that if you simply extend the lamps to the existing boot aperture one ends up with very small radii on the lamps’ inner corner. Mercedes did not want the lamps to have sharp corners: the whole car has quite large radii but especially the lamps are all given relatively rounded corners.
So, if one is to solve this problem and try to respect the general styling theme one must keep the large radii.
So, in the first version I simply extended the lamps inboard and re-angled the boot to make it wider. However, this created a problem that the angle of the boot aperture was not parallel to the lamps.
So, my second theme now has lamps that are parallel to the wider boot and have large radii. What Sacco would say is that this lamp form would be too square and not expressive enough. You can see that from the back in this slide show.
You’ll have to squint a bit as these are hastily prepared sketches based on a ropey source photos but I think you plural get the gist.
I have learned that in car design everything hangs together with everything else. There is also the case that the version as designed could be said to be nicer than the rational versions devised by Messrs. Callaghan and Herriott and the overall look mattered more than the details.
