...unless it's done for marketing (BMW) Smiley

I dont know about marketing thing, but I`ve noticed BMW cars are getting a bit lighter. New BMW 7 weights around 1700kg compared to predecessor`s 1950kg. BMW i3 weights around 1200kg, and i5 weights around 1450 kg. All those cars are lighter primarily because of CF usage. 

Porsche could be criticized for using marketing in wrong way too. They are calling themselves sports-car company, but they dont care about their sports-cars getting heaver & heavier (for now).

It is very expensive to make a car lighter below a certain weight limit and this cost would be passed on to the consumer in any case. Something which no one would like to happen.

IMO the important thing is how a car drives and how much it consumes irrespective of weight. For this there are many technologies available which cost less than lightening a car. Rear wheel steering, for example is a trick to make a heavier car handle like a lighter car without adding huge costs for light weight materials.
