E63S vs S6
The Mercedes rides beautifully and handles smaller. It feels like it can be used as a comfortable luxury car with an edge always there when you want it. It is super fast but the styling of the rear end in particular is a bit dated imo. The screen and tech are dated and a new gen is soon upon us.
A new S6 is at least three years away. The interior is beautiful and there is a sport exhaust option making it a bit fun and nasty. Yes, it is a bit slower but I can live with it (RS7 is not attractive imo). Exterior in red S6 looks cool.
I honestly do not care about the price difference. I want the car I will enjoy more. My wife is on her second E 350 wagon and it is a wonderful family car but the nav etc is really old school vs BMW. I currently drive a 2013 M6 convertible and find the ride a bit harsh for my 40 mile round trip on the bad roads around here.
I know I am rambling and this is a Mercedes forum but I wanted to try and get objective thoughts from other enthusiasts.
Thanks...
No love for the Audi, eh?
I can tell you, having driven the APR tuned S6 that they're getting 550hp at the crank, nearly 500 AWHP and running ~3.5 on pump gas. Thats just the basic tune for $1,500. That puts you right around e63s stock figures.
When I had this debate I figured that the price gap in the S6 vs E63s wagon have me a huge budget for mods on the S6 before I hit price parity. Not sure if you're into that -- but rest assured APR can make that S6 a bullet if you want to go there.
I still went with the E63s . . . because hot wagon! I think the s6 looks very vanilla.

I can also say that as powerful as the car is stock tuning it has made it much more enjoyable to drive, with a torque increase you can really feel from 2-4k rpm I find full throttle needed less often but watch out when you drop the hammer lol
Both great cars and the S6 can save you tens of thousands of dollars, that said my money went to the E63S

I'm a little biased, but i would choose the S6 over the benz in it's current iteration for sure. I was debating the E63S wagon vs the RS7 for a long time and for all these reasons and others i went with the audi. Now if only MB would refresh the E63 in all these ways mentioned, i may have bought it.
Since you like red...

I believe the S6 and S4 share the same engine, just tuned differently. If you get it tunes, and I'd go with Revo and not APR, you will void the warranty.
The Audi Quatro, a supercharge engine, and the rear differential make the S6 a wonderful car. You may want to put KW 3s on it to make it corner better. Not that it corners poorly, but a set of good coilovers make for very secure, and fast cornering. You could go for the adjustable dampening suspension and and KV HAS to convert the ADS to coilovers.
That said the electronic steering of the audis is very vague. My suggestion is you troll the Audizine forum and ask what people complain about the car and see if you can live with some of the issues.
The S6/S7 engine is 4L V8 TwinTurbo, more related to the RS7 actually.
This video compares the S6/S7 engine to the RS7 engine internals and what they did for the RS model to beef it up.

I just can't cuddle up to the W212. That Bi-turbo engines potential is tempting though.
I think that the Audi wins on overall aesthetics and interior design.
The Benz wins on reliability and speed potential. I would never own an Audi that is out of the original warranty ever again

The Audi S6 has better resale than an AMG.
I think a more fair comparison is the W205 C63s.
The W213 should push all the buttons for me, but by then a new S/RS6 should be close.
Then there is always the S8, which I think is a lot more car than the E63, for just a bit more (comparably equipped).
Ahhhh, first world problems...lol!
I am grateful for all the thoughtful comments. It's all good!...




This was not the deciding factor, but the more compact E63 was a better choice for me.
Try these out guys...

They are awesome rides and they look stunning. You can chip either and turn them into a speed monster
