The main radon BMW did it, and never mind the press releases, is because they are experimenting with the best way to include composites into the regular manufacturing process. Not because they take 5 lbs off the roof of a 3700 lbs car.

They're just perfecting techniques for cheap and rapid CF manufacturing in preparation for the I3 which will be the first mass produced CF car. Mercedes doesn't care about that, they will just slap some turbos on a V8 and call it a day.
