Large Sedan.
S also perhaps stands for "SUPER" meaning it required higher octane gas for the high compression engines, and may be also because of its opulence. I guess no one really know where it came from. But what is for certain is that the L (in 300SEL, 400 SEL etc.) stands for a long version of the sedan which has a wheelbase that is a few inches longer than the regular sedans. Since the W140s were introduced the L has follen into obscurity and S classes are now offered with a single length wheelbase: sad!
the 'L' has not been dropped from the line and can still be had. As for what the 'S' stands for it means that the sedan or saloon depending on which country you come from and the 'E' in 'SEL' stands for electronic fuel injection these letters have stood for these meaning since they were first put on the back of the flagships of Mercedes Benz
The S's stand for side-side-side.
