It's been several months since Audi unveiled its latest A8 flagship sedan, and you know what that means, boys and girls: that's right, a new S8 is almost upon us.

The performance version of the luxury limousine has been spied undergoing what looks like final testing, given a lack of camouflage or body cladding on the test mule snapped in our high-res image gallery. The face looks more aggressive than the stock A8 but rather subtle and still tastefully elegant, with bigger wheels filling the wells and larger brakes in turn filling the wheels.

But, of course you want to know what's under the hood. Don't we all. Following a similar trajectory to arch-rival BMW's latest M5, word on the street is that the Lamborghini-derived V10 from the previous S8 will be replaced by the new twin-turbo V8 expected to find its way as well into the new S6, S7 and Bentley Continental GT. Output and efficiency are expected to increase, however, with power ratings mooted in the 500 horsepower range.

That's a lot of beef, and if we had to guess, we'd say we'll probably be scoping it out in person come September's Frankfurt Motor Show.

      It would be nice if you guys actually understood what you were writing about. The S cars do NOT compete with the BMW M cars (RS do!), they compete with the high end "normal" series cars. S8 = 750, S6 = 550, S4 = 335.

        or even the fact that the A8 doesn't compete with the M5 to begin with... "Following a similar trajectory to arch-rival BMW's latest M5" Please ban Noah from posting articles on AutoBlog please! In all honesty, many years ago S4 = M3 (10+ yrs ago), where BMW didn't have an answer to the RS. Times have changed though.

          They're just commenting on the fact that the S8 will ditch a V10 in favor of a V8. Not that they compete. Reading comprehension....

        You're 100% right about the S4 and S6 but I think the S8 a notch above a BMW 750. If the current rumors are correct, next year's A8 will see its 4.2 switched to a turbo V8 with upwards of 400hp, that will be Audi's answer to the 750. On the basis of numbers alone you could argue that this S8 will be perfectly matched to the S63, a car that as currently no German competition.

        I feel as though the Audi S models' should actually compete with BMW's M and M-B's AMG models in relation to performance. Audi's RS models should then compete with the likes of M-B's AMG Black Series' models, the limited ones that they do produce.

        I fully agree that the new S6 will be in the same performance class as the 550i/xi and that the S4 is meant to compete against the 335i/xi. But with 500hp+ the S8 is going to be a notch above the 750i/Li/xi/Lxi. The fact is that the A8 will very soon get a lower-tune version of the V8 turbo with around 400hp, putting it squarely in 750i territory. However, BMW does offer the Alpina B7 which makes a perfect S8 competitor.

      The previous A8 looked better in my eyes.

        the 94-02 a8/s8 was the ultimate. long, low and super wide. this looks too bunched up and fat. i drive an 01 s4, and can appreciate simple/clean styling, but i have no love for audi's new designs.

        I think so too! The front end on this new one looks droopy in comparison

      ugly front butt. Audi has to tweak that front end and soon.

      Jaguar XF Supercharged is all I gotta say. Oh and often with Audi you spend more to get less.

      Don't want no turbo V8. Give me the turbo V10 in the R8. Nu-UH to this S8.

        the R8 doesn't have a turbo.

        btw. the new turbo v8 is developed together with bentley. pretty sure it will blow people away.

      This current generation, although very nice, is truly understated and very subtle compared to the S-Class, 7-Series and XJ. I'm going to miss the V10 of the last generation S8.

      I love Audi's for their (mostly) understated designs, but this one is perhaps too understated. There has got to be something more interesting than quad oval tailpipe tips, with perhaps better integration into the rear diffuser. Still hot, though.

        @jessesrq - That's precisely what I like about most high-end Audi's too. Their understated design makes people believe your just driving any old car, whereas you are experiencing an excellent driving experience and a high-quality well-built interior. However, their lower-end cars such as the A3 and A4 seem to be the opposite. They keep many features derived from their siblings, and I think Audi are the master of unifying design traits across their whole range, but their lower end cars try too look too flashy. The daytime lights are an obvious example, they look great on the R8 and S5 but they just look pretty ridiculous on the A3. That being said, if daytime lights are proven to improve road safety then why not have them across the range. It's not like even their lower-end cars are cheap.

      What I love about Audis. Good looking without being flashy, something hard to manage in an XJ, S-Class or 7-Series.

      It just doesn't look big enough. That was always my most favorite thing about the 8
