In most markets, the W220 can be ordered as:

S280, V6 2.8 liter, SWB
S320, V6 3.2 liter, SWB/LWB
S430, V8 4.3 liter, SWB/LWB
S500, V8 5.0 liter, SWB/LWB
S600, V12 6.liter, SWB/LWB
S320CDI, V6 3.2 liter turbodiesel, SWB
S400CDI, V8 4.0 liter turbodiesel, SWB/LWB

It is a shame the U.S. market limits its customers to just a few choices.
