Can anyone explain Mercedes Model designations? What do the letters and numbers represent?And lastly, why are the letters sometimes before the numbers and sometimes after?

 

well letters represent the class of the car. There are various classes, C, E, S, M, SEL, SE, CLK, CLS, CL, and a few more. The C and E class are lower class than most of the others but still good cars. CL actually used to be S class but it was a coupe so they changed it's name. There is no reason I can think of that some letters come before or after the number... The numbers represent the size of the engine. for example a mercedes benz S500 has a 5.0 liter engine, a mercedes benz E 320 has a 3.2 liter engine. Hopefully that answers your question.

 

ok

 

Thanks

 

The numbers were supposed to tell the engine's displacement, but that isn't always the case now.
S600 now has a 5.5L instead of 6.0L, it had a 5.8L for 2001-2002 models.
E240, this engine has 2.6L
180 / 200 / 230 kompressor are all 1.8L inline 4,

 

That the numerals represent the exact engine size is clearly not the case. Case in point: The 2007 C230 V6 is a 2.5L, not a 2.3L as the name suggests.
