    Traded 2021 RS7 For 2021 S8 - My Comparison

    Guest-only advertisement. Register or Log In now!
    Greetings. I recently did something that many people think is idiotic: I traded in my 2021 Audi RS7 for a 2021 Audi S8! Thought I'd post some pictures and write about the differences between the two for anyone who cares. I bought the 2021 Audi RS7 in 2022, which was my first Audi. It was black on black and had every available option except for night vision and carbon ceramic brakes. I loved the car, it was very reliable, and it turned a lot of heads. Truth is, I've wanted an Audi A8 for the past twenty years. When the A8 was redesigned for the 2004 model year, I remember seeing it and immediately falling in love. To me, it was the most beautiful full size luxury sedan I'd ever seen, particularly in long wheel base. Of course, the A8 has gone through body style redesigns since, but my love for the A8 never waned. Fast forward to present day, and I have been lusting over a current body style S8 since it came to the United States for the 2020 model year.

    I have virtually zero complaints about the RS7, but it's the A8 (well, S8) that I've really wanted. Finding an S8 with all of the option packages I desire turned out to be really difficult. I'd usually find one that had the right color combination, but the options weren't there or it had those awful black rims. A few months ago, I stumbled across a CPO 2021 S8 with 26,000 miles at an Audi dealer in Minneapolis. It had the Audi Care prepaid maintenance and the dealership agreed to put new all season tires on it instead of summer tires, both of which save me a lot of money. I live in Indiana, so I have no interest in swapping out summer and winter tires, and purchasing a second set of tires, like I did with my RS7.

    Comparison observations: The S8 is obviously a larger car, but it doesn't feel, drive, or handle all that much larger-feeling than the RS7. They both have rear wheel steering, so that helps. The rear seat room in the S8 is gargantuan, and my S8 has the three-passenger rear seat comfort package which includes powered, heated, ventilated, massaging, memory rear outboard seats. It also has the rear removable center armrest tablet which controls HVAC, seat, lighting, shades, and stereo settings. In terms of acceleration, to me they feel almost identical. I am surprised how spry the S8 feels compared to the RS7, as it gets up and goes about the same as the RS7. Surprisingly, there are a couple of videos on YouTube where a current body style S8 reached 60 faster than an RS6 and RS7, which makes no sense considering the increase in size and weight. But regardless, I feel as if the S8 and RS7 accelerate almost identically. I lost some cargo versatility with the S8 since I lost the hatch back, but so far it hasn't been a detriment. One of the MOST appreciated features in the S8 is the fact that I can actually adjust the headrests! I hated that the RS7's sport seats didn't have adjustable headrests, and I couldn't use them comfortably as I always could with prior vehicles. The seats in both cars, however, are very comfortable.

    The S8 has the predictive active suspension ("PAS") which isn't available on any other Audi model, and boy does it have some great party tricks, most of which I find more gimmicky than desirable. The PAS does the following, in no particular order: 1. when you open any of the doors, the entire car quickly lifts up about two inches to help aid entry; when all doors are closed, the vehicle slowly lowers back to its original height. 2. if you floor the gas pedal, the suspension automatically lifts up the rear end to counteract front end lift such that the car stays virtually flat; contrarily, if you slam on the brakes, the front end lifts up to counteract nose dive. 3. when you turn into a curve at higher speeds, it elevates the side of the car on the outside of the curve to counterbalance the forces you typically feel when going around a curve. 4. when its front camera appropriately reads and detects a speed bump, the car lifts up just before you drive over the speed bump such that you don't feel driving over the bump near as much as you typically would; in other words, the suspension readies itself to "eat" the bump and sort of glide over it by increasing the space above the tires to absorb the impact. 5. if the car detects you're going to be t-boned, the side about to be hit lifts up so that the cross beams in the doors absorb the brunt of the impact, thereby better protecting vehicle occupants. I hope I never have to find out if this PAS feature actually works!

    My RS7 and S8 both have the expensive optional Bang & Olufsen Advanced sound system. The S8's stereo sounds better than the RS7's, particularly because there are a lot more speakers in the rear, including in the rear shelf which the RS7 doesn't even have due to it being a hatchback. One thing that always bothered me in the RS7 was that you couldn't really hear the music coming from the back seats. There is a small tweeter on either side of the rear head rests in the RS7, but they have virtually no sound emitting from them. They were totally useless. With the S8, it has a legitimate rear shelf, so there is more sound emitting from the backseat area. The stereo in the S8 just sounds more innate and "organic," as if it was designed as part of the vehicle from the beginning. The RS7's stereo sounded more like they installed 19 speakers after the car was complete, and the sound isn't as enveloping as the S8. Definitely not worth the $5,000 price tag. As a side note, for those of you who aren't impressed with the Bang & Olufsen stereo in your Audi, particularly because you can't even control the midrange, try using Spotify which has its own built-in equalizer - I guarantee you the sound quality will significantly increase as you set Spotify's equalizer to the way you like it. And don't forget to select "very high" sound quality in the settings and TURN OFF audio normalization.

    Finally, I'll note some features in the S8 which I like, and which can't be had in the RS7: massaging seats; hidden dash vents which disappear behind motorized doors when the climate system is turned off (yes, totally gimmicky); ionized air; dual sunroofs; rear powered window shades (all three rear windows); powered adjustable headrests front and rear, rear seat comfort features; all-seat memory settings; heated armrests; and quasi-hidden storage cubbies in each door armrest.

    The RS7 definitely has cooler looking headlights, a sportier appearance, and more head-turning looks. I have nothing negative to say about the RS7, and I can't necessarily say that I think the S8 is better - I just like the extra room, comfort, and features it offers. I know this was a long post, but oh well. I'm bored and enjoy talking about cars. I hope someone finds this helpful. Let me know if you have any questions. Pictures are below, including the S8 and RS7 side by side at the dealership. Happy holidays!

    That's a really nice review and it certainly sounds like a fantastic car! I'd love to have some of the S8's features in my RS7 (I just got a 2024 RS7, hah!). The suspension on its own sounds pretty damned impressive, and I did not know that about the S8's capabilities. I would agree w.r.t. the B&O advanced sound system - my RS7 also has it, and TBH I can't really tell the difference between it and the standard B&O system that was on my previous car, a 2021 A6 allroad. Funny thing about the adjustable headrests - I really didn't like them on the A6, and my wife hated them (it was at just the wrong height for her, so it would push her head forward and down), whereas the non-adjustable sports seats on the RS7 are much better for her, and I also prefer them. You can now get different seats in the RS7 that have adjustable headrests and a massage function, btw. Also, thanks for the spotify tip - I use it extensively, but had not tried using their equalizer. Quite a nice difference!!

    Before I bought the 2021 Audi RS7, I had two Genesis G90 sedans in a row, both with the 5.0 V8 (a 2018 and a 2021 - not the current body style). Both of them were wrought with technological and mechanical problems, and I said sayonara to Genesis and switched to Audi, with zero regrets. I'll never go back to Genesis. But the one thing both Genesis G90s had was a WONDERFUL, exquisite, awesome, amazing sounding 17 speaker Lexicon stereo. To this day, that Lexicon stereo is one of the best, if not the best, I've ever heard in a vehicle. No joke. And I've listened to a lot of top tier vehicle stereos. I miss that Lexicon stereo tremendously. Otherwise, I miss nothing about those unreliable heaps. With those Lexicon stereos, it didn't matter what music source you fed it (FM radio, YouTube from your cell phone, a CD - anything, regardless of it being played with a cable or wirelessly), it sounded wonderful. I'm not an expert on audio technology, sound processing, or the like, but I know a good, high fidelity stereo when I hear one. My theory is that Bang & Olufsen's processor and/or amp can't maintain the fidelity of the music source running through it. The Lexicon could, no matter what. If I played a high quality song via YouTube from the app on my cell phone, it pumped through all 17 speakers in high quality. With the Bang & Olufsen stereo, YouTube sounds like absolute garbage, as does FM radio. Yes, I totally understand that those two sources aren't known to be good quality, but my point is that it didn't make any difference with the Lexicon stereo. My biggest complaint about the Bang & Olufsen stereo is that it's muddy with almost zero treble, and there's no midrange adjustment. I honestly wish I could sit the highest-level Bang & Olufsen technician in a G90 and play a song from YouTube (for example), then play the exact same song from YouTube in the RS7 or S8 to prove how crappy the processor is in the Bang & Olufsen stereo. I like high treble and crystal clear audio. I was severely disappointed when I bought my RS7 and found out how lousy the Bang & Olufsen stereo was. After doing a lot of research online, and after some trial and error, I thankfully found out that using Spotify helps tremendously. I've attached a screen shot of the equalizer settings in my Spotify app in case it helps someone. In the car's stereo settings, I have the treble turned all the way up, and bass almost as high; then using the Spotify equalizer, I'm able to get the treble and bass to where I really want it such that it's damn near just as good as the Lexicon stereo. Anyway, I could talk about this issue for days. I'll move on.

    With respect to the seats, I found them to be supremely comfortable in the RS7 and the non-adjustable head rest was the perfect height, but it was too far back for me to actually use. If I leaned my head back to rest, I was simply leaning too far back for comfortable driving. With the S8, the headrests are adjustable up and down, and because the seat itself has a lot more adjustments than the RS7's front seats, I can tilt the top half of the seat forward so the head rest is better positioned and useable. One more G90 rave: the front headrests could be move forward AND backward, as well as up and down, so you could put the head rest closer to the back of your head. Can't do that in the S8. Oh well. Third world problems.... I know that you can pay extra for the optional comfort seats in the RS7, but they do not look sporty and, in my opinion, such a powerful sporty vehicle deserves to have the sport seats.

    One thing I absolutely love about the RS7 and S8 is the Google Earth maps in the MMI, as opposed to a generic digital map in pretty much every other non-Audi vehicle. It's helpful to see the actual topography when you don't know where you are. I do miss the capless fuel filler in the RS7. It was handy not to have to unscrew the fuel cap. The S8 has a fuel cap. Another difference: the RS7 displayed the current PSI of each tire, but in the S8, you can't display the PSI. It will only alert you if a tire is low. Lame. I hope you love your RS7. It's a great car. What are your thoughts on it so far? Fun fact: press either of the front overhead ceiling light lenses, which is how you turn on the light as it doesn't have a separate button, and keep your finger on the lens. The light will dim until you let go! It lets you adjust the amount of light.

    Nice short review , very informative. Is there any particular reason why you guys choose the RS7 and not the RS6? Preference? I see so many RS6's on the market for sale

    I’m just not a fan of station wagons. That’s all we had growing up. And the RS7 looks more sinister and aggressive, in my opinion.

    Ah yeah - I totally agree with you regarding how they look. I just wasn’t sure if you knew it was an option now (or may have been in ‘21).

    I love it! It’s a fantastic car. Heavy AF and not as nimble as my 911, but my 911 is biased much more to the track with a bunch of modifications that I’ve done to it. I’ve got similar HP in the 911, but it’s a manual transmission and is 1600lb lighter than the RS7, so it’s like a go-kart in comparison (which is funny because in comparison to the Cayman, it feels heavy). So it’s not a track car, but I didn’t want that. I came from an A6 Allroad (and and S4 before that), so I was OK with a somewhat heavy car, but wanted something more sporting than the A6 allroad. The difference between comfort, dynamic and RS1/RS2 modes are quite marked - far more so than I was expecting, and the acceleration is impressive - it never really feels like it’s lacking, no matter what the RPM is. The seats are fantastic, super comfortable, and I love the A6/A7 interior ergonomics. I just finished the break-in period, and I managed to get a 0-60mph run on a closed course - with a 1ft rollout it’s 2.86s (3.08 from a standstill), so it’s impressively quick. The suspension - standard air suspension, not the DSC - is great and just what I wanted. I didn’t need a super stiff suspension for this car. I love the practicality of the hatch - I needed that, and coming from an A6 allroad, that was one of the biggest requirements.

    That’s awesome - I did not know that. I feel like I should, because it’s the same in the A6 allroad, but I never read the manual. Oops.

    I came from an A6 allroad, which is effectively mostly the same body as the RS6 avant. I just didn’t want another station wagon - to me, it’s kinda like a mom wagon. I feel exactly the same about SUVs, so the RS Q8 was out the window as well; at least the avant drives like a car as opposed to a roly-poly tippy-toppy SUV. Even the Cayenne GTS was too much of an SUV for my liking. While the station wagon body is super practical, it boiled down to the fact that I didn’t want another station wagon - I just went through 3 in a row because we did a lot of bicycle racing until recently, and that was a requirement (or an SUV, but see above about the SUV). I needed a hatchback, so that ruled out a BMW M5 (and TBH I don’t really like BMWs anyway), and I really wanted to splurge on a high-powered sledgehammer of a car. Given that it had to be a hatchback as opposed to a sedan, couldn’t be an SUV, and not wanting another station wagon, I basically narrowed it down to a class of 1 - the RS7 Performance. I could have gone with the RS5 sportback, but I didn’t like the interior of the current one (don’t like the sticky-outy navigation display in the cabin - I find it interferes with the driving view), and I didn’t want to risk the new RS5 sportback being a stupidly heavy hybrid as it is purported to be. I’m sadly also not super wild about the new dashboard in the new A5/S5/RS5. Also, 621hp.

    And it goes without saying that I was not interested in an electric vehicle. At some point I’ll have to get one, but I’ll be delaying that as long as I can - they just do not stir the soul for me. And there’s that minor issue of too few charging points nearby, decreased range in cold weather (and we were at 1ºF this morning), massive depreciation that all EVs are seeing, and the utterly boring personality of the soundtrack that they produce.

    I like your assessment. I have an RS7 (24) and my wife has a 23 S8. I agree with everything you said. The one thing with the S8 is that the acceleration is more quiet than the RS7. It's just a little more refined. It's a great highway cruiser other than a few rattles that crop up occasionally. No complaints with either.
