Cosmetically there’s not much in it… just something about the front of the rs6 is just that touch more interesting but maybe not ‘better’ - I can only put it down to the black grill has more contrast and the headlights seem to look better (can we fit those to s6 without changing grill :)?)
Plop do you have a better picture? On my phone it is super blurry
If you click on it, it opens a higher resolution version
In theory you should be able to bolt up the front bumper cover as that is what seems to be the only difference in the front end.
The side skirts are nice and easy to put on but the lower rear bumper has what looks like an extra piece on the RS6.
Like you said tho. Really the front end is the only really standout WOW difference.
front and rear wheel arches have a subtle squared bulge that’s pretty hawt.
I did not realize the panels are different? In the bottom pic they look almost identical, but now I can see. I guess black is not the greatest colour to show it off with.
I actually prefer the S6 alloys - that particular style on the RS6 are nice, but I feel have been done to death… look a bit dated now.
Yes front and rear arch panels are noticeably wider
Maybe the US versions are different
Sadly, there is no US version of the RS6.
I can’t tell you how big my softspot is for squared off fender flares. God I miss IMSA and CanAm… 
the black grill, the lights are definitely cooler with that flat line in the top of them that makes the car seem to scowl a bit. Seeing them around Europe a couple years ago I loved it.
The whole car just looks sharper and more angular and more nifty.
Most importantly the RS6 also has big flared box fenders that the dark underexposed comparison pictures above unfortunately skip. The A6/S6 looks relatively slab sided in comparison. And the pictures don’t show the wider door sills.
Let’s have a wake up call shall we?

I have the RS6 Bumper on My S6 and am installing the headlights shortly. I brought the bumper back with me and the headlights. just haven’t gotten around to the headlights. The rear is significantly wider fender flares would be necessary in order to bolt up the rear bumper from the Rs6
key^^^
yep, now I see different aspects and better colour they absolute beasts…
It’s all relative I suppose, there’s a guy who parks near me who’s done everything under the sun to make his TDI A4 look like an RS4. I was amazed there are people trying to make their A6 look like an S6. It must be such a relief to not have to bother with all this if you own an RS ;D
Ah yes the famous rare 1.9 TDI RS4 models, lots of them in Ireland too! oil burners!
hahahaha that’s funny because it’s true.
When I owned an S4 I was always annoyed that there was a much better version of the car floating about. I ended up buying an RS4 when my S4 was a bit long in the tooth.
So just to clarity - are the panels on the S6 identical to stock A6, or are they just lest flared than RS6?
The front fenders are wider not sure about the rears
most of the body is the same as A6 S line
fenders (panels) are the same as basic A6 but bumpers and door blades etc are different
It looks like the front wheel arches are more flared than stock A6, or is that just me eyesight.
