I cannot make up my mind between these two cars.

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...

What about the new c63S? It's bigger and better tech

Rwd though

I agree that the exterior appearance and nav screen/tech on the E63 S are a little outdated. But oh that engine power and engine/exhaust noise.

ABWAP

Both the M6 GC and the C63S appear to be great cars but I do want 4WD. At a certain point, that much power needs it. On my current car, if conditions are not 100% ideal in terms of smooth roads or temperatures, the traction control light is kicking in a lot.

No love for the Audi, eh?

On E63s vs S6 speed. If you're talking stock then yes, but I tend to compare this these figure after a modest ECU tune. Still 100% reliable and daily drivable. I've done this to all my Audi's with no issue. I haven't done the RENNTech tune to my E63s but considering.

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.

What about the Alpina B6? That might fit your bill....

I like the S6 and seriously considered one as there were some things about it the E63 couldn't match however the E63 I think was a better total package and had options available such as CCB that the Audi didn't have.

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 agree the looks of the mb are dated, especially now that the 2016 S6 is getting a cosmetic refresh (front/rear lights, flat bottom steering wheel, tech update etc...). Inside the cabin, the S6 is superior imo in addition to the tech which is way beyond the benz. Performance-wise both are pretty sweet and as mentioned the S6 can be tuned very easily if you want to go in that direction for just a few bucks. Stock for stock the benz is likely the faster of the two if that matters to you. For me, both vehicles are much more capable that i can use here in north america so it's pretty much a moot point imo. The S6 has a dual clutch transmission vs the antiquated wet clutch in the benz. There are quite a few e63 owners who complain about the transmission on this forum at least. I took an E63S wagon for a test drive and i didn't notice any issues, but best to do some more research into this yourself if the type of transmission is important to you. The 2016 S6 refresh also gets a power bump up to 450hp i think.

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...

+1 on all counts. TT850 is 100 percent right about watching out when you drop the hammer on a tuned E63 S. The acceleration is really astonishing especially for a large sedan. He has the AMS tune and mine has the Renntech full tune. They are rated at about the same power. Either will make the car fly in a way that an S6 cannot keep pace with.

I'm just coming to an 2014 S4 to a 2012 E63 AMG wagon.
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.

You couldn't pay me to have to rely on local Audi dealers for after-sale support. NFW.

The S6/S7 engine has nothing in common with the B8 S4 engine which is a 3L V6 Supercharged setup.
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.

Worth the wait

This is a tough call....and that's from a nut-swinging, AMG Fanboy.

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!

Good video. Thanks.

ABWAP

It does check off a lot of the requirements but doesn't feel different enough from my current car to get me excited. I have just owned two BMWs in a row and I think I'm ready for a different marque.
I am grateful for all the thoughtful comments. It's all good!...

Munich77

If you are in that price range what about a Panamera or RS7?

ABWAP

RS7 design does not do it for me and I do intend to try a Panamera GTS or turbo. Both good suggestions.

I also looked at these 2 cars but since my garage space is limited, I found that at 197.4" they were both 5" longer than the E63 at 192.4"
This was not the deciding factor, but the more compact E63 was a better choice for me.

forcefed4door

I'm in the same debate. But from all my research with the standard awd, better gas mileage, better overall appearance in and out, the audi is tipping the scale for me. E is Def. More powerful no matter what mods you do, but there are to many other variables where audi comes out on top imop

ace10

The Panamera is absurdly long. I've been parking our plug-in Panny in the garage this winter, and it inhales space around it like a black hole. I had no clue it was so large until I tried to park it inside.

ABWAP

I drove an S550 coupe and I was very very impressed. Interior is incredible, it gets a lot of looks, handled surprisingly well and had a nice raspy exhaust upon start up. I've driven the 4 door and the 2 door felt much better than the sedan. I'm waiting for the S63 to arrive at the dealership to try it as well. I know they're a lot more $ but I'm getting one of the two.
Try these out guys...

Munich77

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

beegee227

I went a similar path as you. 2012 Audi Avant Prestige S-line to 2012 E63 Estate P30.

ace10

S550 coupe can't hold a candle to the performance of the E63S, and the S63 is 1.5X the cost. Can't see either as a competitor to two cars you originally asked about. Especially from a seating perspective.
