Therefore a C350 Estate 4Matic would be +15kg over C350 sedan 4matic = 3825 lb/1735kg
So GLK is 211lb heavier than the C350 Estate 4matic. I wonder where that weight is?
More glass and sheet metal due to taller roof?
it could be the wheels and tires as they are different size altogether.
and if you can check the gas tank size, that would be the other reason, perhaps?
If you really want to take some weight off, remove the spare tire and save about 40-50 lbs instantly!
I'd guess it comes from more sheet metal, bigger wheels and tires, tougher suspension and frame parts (again more metal).
