Audi's S6 is a high-performance four-door sedan and the S7 is the automaker's high-performance five-door luxury hatchback. The two are platform-sharing siblings with common 420-horsepower twin-turbocharged 4.0-liter V8 engines, seven-speed dual-clutch automatic gearboxes and permanent all-wheel drive. No surprise, then, that straight-line performance between each is indistinguishable from one to the other. Based on this information, many casual observers are led to believe that the only discernible difference between the two models is found in bodystyle.

We recently had the opportunity to drive the S6 and S7 back-to-back on our favorite Southern California canyon roads. While it wasn't a track environment, we pushed each pretty hard until distinct personalities and driving dynamics were revealed. We also learned a few other interesting things about the close siblings:
  • On a scale, the S6 (4,398 pounds) is 110 pounds lighter than the S7 (4,508 pounds). The additional weight in the S7 is due to structural reinforcement for the hatchback – possibly meaning there is more weight over its rear axle. (Audi has not released weight distribution figures.)
  • By the tape, the S7 has a slightly wider front track (up 1.1 inches) and rear track (up 1.2 inches), and its body is 1.4 inches wider overall. The S6 sedan is 1.9 inches shorter in length than the S7 hatchback. (Audi has not released center of gravity height.)
  • Despite sharing the identical electromechanical servotronic speed sensitive steering, the system in the S6 delivered a more direct feel and effort felt slightly heavier. The S7 steering felt marginally lighter and less accurate.
  • The S6 felt more balanced in the corners, even though it was the narrower and taller of the two. Mid-corner corrections were more stable in the S6, as the additional weight over the rear of the S7 caused a tiny oscillation as it corrected itself in the same maneuver.
  • The S6 was wearing Pirelli tires, while the S7 was shod in Yokohama rubber. Audi says both tires should perform nearly identically, but we'd beg to differ.
  • Audi's official 0-60 time is 4.5 seconds for each, but using the gearbox's (secret) launch control feature drops each to about 4.0 seconds flat.
The S6 has a base price of $71,900 while the S7 starts at $78,800. Based on our short comparison, if you're not interested in the S7's form factor or trunk space, we recommend the driving enthusiast should save $6,900 and go with the S6.

      4 seconds flat to 60 and they are not even RSs

      These cars look totally different from one another. Look at their profile and their rear ends. S7 is the better of the two if I were to pick. Looks alone are worth the money, plus when you go to sell it, I bet it holds more value.

        So when both these cars approach you from the front (which ALL cars do) you will be able to distinguish the two? These cars should be distinguishable not only from the rear but from ALL perspectives, like all car designs should be.

          The VW MLB platform is bound to see usage across VW Group's brands, even though currently not used for any VW models. At least for now they share reliability ratings due to their identical design and manufacturing processes. Next question is, is that a good thing?

        OK, that was just a massively stupid comment. Massive. I don't always believe German cars are superior to the Japanese. In fact the two best cars I've owned have been Japanese. But "No real car enthusiast would ever buy a German car."? That is quite possibly the dumbest statement I have ever read on this site.

        Um, what? They clearly state that with launch control they run to 60 in 4 seconds. That's a few tenths faster than a stock Camaro SS. I fail to see how being slower equates to spanking another car. Besides if these had 520hp how much are you going to give the RS6? You can't have an S6 making 520hp when the S8 is making the same. These cars are better in any discernible way than a Camaro, regardless of price.

        • 2 Years Ago
        Camaros are getting sub-four-second 0-60 times now? I thought that they were still testing in the mid-fours. Either way, these cars are far from being underpowered.

        Please refer us to the test where a stock Camaro SS runs faster than 0-60 in 3.7 seconds and the 1/4 mile in less than 12.1 seconds at more than 115 mph. (those are the S6's stats from the recent C&D comparison test, which it WON, BTW, against the M5 and E63)

        @ihyln
        wait, was this a serious comment??? You are comparing a tiny, high revving V8, to a twin turbo set up with tons more torque??? Just to put it into perspective btw, a stage 1 tuned BMW 335 (N54 engine) and a stage 1 tuned Audi S4, will both DESTROY a BMW M3 or Audi RS4. Your comment shows your stupidity. Even if the M3 is faster, the S6 and S7 are in another class. But the point is, it is NOT faster and has no low end torque for DD. That is why even though the M3/RS5 have the chops to race on a track, the C63 AMG and Lexus IS-F are better as DD.

          • 2 Years Ago
          @libertedelacroix
          haha S4. Good one. More expensive than a 335i yet also slower and heavier. What class is the S6 and S7 in? The S6 might compare to a 550i and that's about it. After you load the Audi up it's already touching 90k, that's M5 money. Who is the stupid one here?

It's HILARIOUS how the luddite Manual transmission folks are completely ignorant of new technology. Here's a top tip for you----all of the world's finest driver's cars are driven by dual clutch transmissions at the moment. If you can't accept that, go back to 1988 where you belong.
