Why is there carpet up in the outside rear wheel wells?

I noticed on my 2nd gen FX that the outside rear wheel wells are lined with carpet instead of being plastic lining like what most other cars use. I've noticed that newer model Mercedes like the E and S class are starting to use this carpet material in the rear wheel wells too. I was wondering what the purpose of it was for?

I heard from another source that it's put there for better sound deadening from the rear end, and it saves on weight. Don't know if it's true or not though.
 
it's not carpet, it's a synthetic material that doesn't absorb water. it's used to block & reduce road noise & it also reduces the sound if you drive over gravel & drive through big puddles & stuff, weight difference probably not that much difference really
 
^Ahhh....I see! Thanks for the info bro. This is probably why I never hear a swooshing sound from the rear when I'm driving through rain on the road. It's usually dead silent kind of.

What I don't understand is why they don't line the front wheel wells with this material. Only the rear wheels have them.

Maybe it's heat-sensitive?

Oh that make's more sense since the front wheels are past the insulated firewall. I also notice the front wheel wells have these vents on them to direct air towards the brakes. So that could also be another reason I guess.
