Actually the shorter or longer wheelbase has not much to do with performance or economy (in Europe and most markets, where all W140s -except the S 280- where available with SWB and LWB, M-B does not list any difference in 0-62 times nor m.p.g. figures).

Although, there is a noticeable (not overwhelming) difference in ride quality from the SWB and LWB. The LWB rides much better. Those extra inches at the wheelbase help.
