What are the definition of Mercedes Benz car C Class and E Class?

Mercedes assigns the letter designation to a model to describe one or more of a car's major characteristics in a general way. Some model letters on older cars from the 1920's and 30's were:

• "K" Kurz (German for Short)
• "L" Lang (Long)
• "V" Vor (Front, engine in front)
• "H" Heck (Rear, engine in Rear)

Model letter designations on modern cars usually mean:

• "K" Kompressor
• "C" Coupe
• "S" Sedan
• "E" Einspritzer (fuel injection)
• "G" Gelaendewagen (off-road vehicle) or Grand
• "D" Diesel
• "T" Turbo or Tourer
• "S" Sport
• "L" Leicht (Light weight)

Mercedes now markets cars according to Class designation. Some Classes are "S", "E", "C", and "M". These Class letters do not appear to have any particular meaning.
