New Audi S8 To Feature Twin-Turbo Porsche Powertrains

Now that Audi has released the new A8, the question on everyone’s minds is when we’ll see the new S8 performance version, and what will be under the hood.

We can’t answer the first question just yet, but Evo has some interesting tidbits about the second. According to the British publication, the new performance sedan is set to employ Porsche power – and even a hybrid version.

Now before you go screaming “what, that’s crazy,” let’s establish a couple of things. For one, the previous S8 employed a 5.2-liter V10 that was essentially adapted from the Lamborghini Gallardo. The current model uses the same engine as the Bentley Continental GT. So the idea of using a Porsche engine suddenly doesn’t seem quite so outlandish, especially when you consider that the new A8 shares its platform with the Panamera.

The engine deployed in the Panamera and being mooted for the S8 bears the same basic parameters as the outgoing model’s: a 4.0-liter twin-turbo V8. But it’s an entirely different block, and where the current S8 packs 513 hp (or 597 in Plus guise), the Panamera Turbo boasts 550 – or, crucially, 680 with an electric boost in the Turbo S E-Hybrid.

That’s where things get interesting, because Evo and its sister-site Auto Express report that the S8 Plus could be replaced by an S8 E-Tron, using the Porsche’s hybrid powertrain. Both versions could end up detuned slightly on their way from Zuffenhausen to Ingolstadt, but not by much.

As it is, the Panamera Turbo S E-Hybrid churns out significantly more power not only than the Mercedes S550e PHEV or BMW 740e iPerformance, but than the AMG S63 or M760i – and more torque than all but the S65.

    Well, if the engine has “Porsche” written on its cover, it will clearly increase the desirability of the model, and will compete better with the S-Class, but at what cost ? Will it hurt Panamera sales (although they are in slightly different segments) ? It remains to be seen.

      No way will an Audi wear any Porsche badging, anywhere. Porsche NOR Audi would allow that. It will be a cover redesigned for the Audi.

    Do you guys do any research before posting? This is a horribly written article and not accurate in the details. First off, the new A8 sits on the MLB Evo platform shared with every longitudinal Audi. The Panamera sits on the MSB platform shared with the next generation of Bentley’s. While the engine was first in a Porsche, it has been co-developed between the two from the get-go, and the drivetrains have different personalities to suit their respective brand. Just like the current TTV8 was developed at Audi and then passed on to Bentley. This is the power of working under an Umbrella. It’s not a Porsche engine going in an Audi. This stuff is old news. Just like the TTV6 that was heavily developed by Audi, which resides in a Porsche first because of their hierarchy in the VAG group.

      So true, no way both cars share the same platform. the location of the engine is simply different on both cars.

    I like the look of the new Panamera better than the A8 so I’m learning toward that being my next sedan. Although I’m holding out to see what the next generation Audi A7, Mercedes CLS and BMW 6 Series Grand Coupe look like.

    • An Existing Person

      I am with you on that. Alongside those, I’m also waiting for the new AMG GT four-door and the next BMW M5 as potential options, or else I would have gone for the Panamera by now.

      • nastinupe

        The M5 is going to be a beast. The regular 5 Series already looks amazing so I can only imagine what the M5 is going to look like. If they offer it up in AWD I would consider that as well. BMW is kind of holding out on the AWD M’s. If they let them loose they will kill everyone’s 0 – 60 and 1/4 miles times.

        • An Existing Person

          The rumors are in fact true; the next M5 will indeed be offered AWD only, with a RWD mode so to say, similar to what Mercedes has done in the new E63. Having driven the new M550i with xDrive, it feels much faster than the current M5. I could only imagine the wonders that system will do for the M car.

      2017 and you’re still talking about slow gas guzzling performance sedans. Get with the times. Drive a Tesla. You’re wasting your money driving anything other than electric nor are you having the best driving experience. But hey if thats how you want to live then thats cool. Uniformed and all.

  • GONNA NEED ALL THE POWER IT CAN GET TO HAUL AROUND THAT MASSIVE GRILLE.

  • sohowsgoing

    The outgoing S8 has the same 4.0 twin-turbo engine that is shared with the S6 and S7, tuned to 520 hp. The upcoming one is expected to have the same. Seriously, no research was done.

    I do love how more and more cars are adding larger and larger engines while our highways get more and more crowded. I can see the 911’s and the Ferraris and the like, for they will see the track, but the rest will see 0-60 into the back of an old K-car.

    I picked up a 911 in Zuffenhausen a number of years back and probably averaged 40 mph in S Germany. The only time I saw 150 was on a new stretch of Autobahn from the former E Germany.

    As for these Audis and MBs with such power, hope the neighbors are impressed.

    • S3XY

      Nothing impressive about these slow gas guzzlers. They’ll get smoked to the speed limit in my Volt.

  • roy

    the thing with the new A8 is that it looks way too familiar and that is because of the fact that it was over teased

  • iamsickofu

    I don’t understand to why all car n SUV builder are putting a lot of horse power and fast for ? Where are they going to use with all those power ? It was just a waste of gas and money and time and even in danger to each other. I would like a safer car and an affordable car for everyone to use

    While this works well for Audi as it lends Porsche pedigree, it terribly dilutes Porsche’s exclusivity. They need to be more careful about differentiation when sharing these engines, platforms, etc. Porsche currently maintains massive markups clearly due to popularity with its carefully crafted image.

  • Elmediterraneo

    This A8 (and the upcoming A6 and A7) don’t use the Panamera’s MSB platform, it’s still based on Audi’s MLB platform with a FWD mounted gearbox, which is the specificity of this architecture. But good news, the next generations coming after 2025 will have Porsche’s RWD based architecture due to MLB’s killing off.
    For this S8 engine, I thought It will have the Urus 650 hp 100% petrol V8 (at least for S8 Plus). Because we already know that the Urus will come in a 650 hp petrol-only version or a 680 hp plug-in hybrid. But the battery’s weight will make the petrol version the more interesting to drive.
    So now that’s completly different so now we can expect from the Volkswagen group :
    – Audi RS6/RS7/S8/RSQ8 : V8 4.0 Biturbo 550 hp
    – Audi RS6/RS7/S8/RSQ8 e-tron : V8 4.0 Biturbo Hybrid 650 PS (550 petrol + 100 electric)
    – Lamborghini Urus : V8 4.0 Biturbo 650 hp
    – Lamborghini Urus Hybrid : V8 4.0 Biturbo 680 hp (550 petrol + 130 electric)
    – Porsche Panamera/Cayenne Turbo : V8 4.0 Biturbo 550 hp
    – Porsche Panamera/Cayenne Turbo S E-Hybrid : V8 4.0 Biturbo 680 hp (550 petrol + 130 electric)
