The Audi A5 was unveiled at Geneva to much fanfare, and within 30 seconds of pictures hitting the net the elegant coupe was been surrounded by rumors. We knew the S5 was part of the package, but since the newest Audi had two doors, cabrio conjecture wasn't far behind. Perhaps the most anticipated A5 talked about is an RS version, which could include either the high-revving 420-hp 4.2L V8 found in the RS4, or the Lamborghini-sourced 5.2L V10 found in the S6 and S8.

The scribes over at World Car Fans point out that the RS version typically one-ups AMG and BMW M cars, and with a 480-hp CLK out there, the Gallardo V10 would make a nice trump card. We're inclined to agree with that hypothesis, since Audi already has the powerplant in the corporate parts bin, and there isn't much tuning necessary to get it back up to 500 HP. Audi has also shown just how serious it is about keeping a power edge against RWD competitors after it had the lug nuts to slap twin-turbochargers on the V10 destined for the RS6 Avant. Either way, Audi is no longer interested in being an also-ran in the luxury market, and big-horsepower coupes will only make the brand that much more appealing to enthusiasts.

      Big diesels are sweet, but very heavy. VW's TDI V10 = 850lbs

      theSAWzall: er, the problem must be in my poor English :)

      what I'm trying to say is that VAG/Audi treats Lambo like "slightly better premium" brand, which is way below what lambo IMO should be
      when Audi participated on development of the new Lambos I had no problem with that (like I was wealthy enough to complain :)), but now it seems like the parts Lambo has from Audi (or Audi developed for Lambo) were only borrowed to Lamborghini

      in my eyes Lambo was always above Ferrari, but it is slowly changing
        • 7 Years Ago
        ''for me the Lamborghini was always more exotic and exclusive automaker (regardless of the lack of sport or heritage)''
        More exclusive!!!!? Their technology is being used by vw/audi (chases, engine, aerodynamics, etc.). On the other hand nobody uses Ferrari technology. One of a kind. It's called exclusivity.
          • 7 Years Ago
          Peter: and when I say "for me Lambo was" I'm talking about the times when Lambo used their own technology (be it less reliable)... moreover Ferrari always produced more models and vehicles (they release like 1+ standalone model per year, unlike Lambo)
          • 7 Years Ago
          Peter: well, nice try, but that's exactly what I'm talking about in comment #2
        • 7 Years Ago
        Why would anyone ever think Lambo was above Ferrari? What heritage does Lamorghini have? Tractors? They never raced a day in their life, and their most iconic car (OK, the Muira is fantastic), the Countach became a parody of 80s excess. I would take a Ferrari any day over a Lambo, and I assumed most enthusiasts were simialr?

      They should use the 580 hp V10 TFSI from the RS6 Avant.

      "after it had the lug nuts to slap twin turbochargers..."

      Now that's good Autoblog writing!
      Helped to muffle my case of the Mundays...
      • 7 Years Ago
      Well, I feel like VAG is quite raping the Lamborghini.

      Yes, I know Audi have almost build the new Lambos, but anyways, they're playing with Lambo-parts like it was LEGO.
        • 7 Years Ago
        VAG is very good at dipping into the parts bin. The Gallardo's V10 is one of the few high horsepower engines that VAG has. That makes it the engine of choice for all these new high horsepower Audi's. The other choices would be the V12 in the Murciélago, or the W12 based on the VAG VR6.

        Maybe we will see another a new VAG developed engine in the future for the Gallardo's replacement.

          I wasn't saying the engine is bad.

        there are not many car producer that can play around with such a wide range of high power engines as VAG

        4.2l V8 420hp n/a
        4.2l V8 450hp TT
        (based on the high rev 4.2l V8 for the new RS4 and most likely the RS5 powerpack)
        4.2l V8 450-480hp TT from the old RS6
        5.0l V10 500-530hp n/a
        5.2l V10 TFSI 450-510hp n/a
        5.2l V10 TFSI 580hp TT
        6.75l V8 510hp
        6.0l W12 420-600hp n/a and TT
        6.2l V12 580hp n/a
        6.4l V12 640hp n/a
        8.0l W16 1001hp quad turbo
        4.2l V8 TDI 326hp
        5.0l V10 TDI 340hp
        6.0l V12 TDI 500hp

        The Lamborghini V10 was developt under the lead of Audi, rumors claim that it is based on Audi´s 4.2l V8.. both engines shares exactly the same bore and stroke
        • 7 Years Ago
        Actually I have new respect for the Lambo engines. If Audi is comfortable to use them and even turbocharge them, then they must be quite reliable. Germans typically have a higher demand for reliability than Italian do.
        • 7 Years Ago
        "...they're playing with Lambo-parts like it was LEGO."

        Haha this is the image that comes to mind:
      • 7 Years Ago
      Oh how i wish we could get past the pedantic of arguing about the V10. It's not a direct swap from Lamborghini, they share very few parts, and they aren't even the same degree of offset between the banks, well they aren't even in regards to design – in short every major factor one might identify to distinguish two engines show no parity between the two.
      Now. Having recently had some dedicated track time with the RS4, S4 and S5, I can easily answer an emphatic “yes please” to the rhetorical of 500hp being nestled in the S5’s front end. It’d be a hoot. I doubt they’d sell too many, but who cares.
      I don’t care either way, I’d rather have the V6 TDI.
        • 7 Years Ago
        Yes 500hp is good.
        The current S5 and upcoming S4 can have their V8 engine upped to about 375hp with the Audi Valvelift system.
        or Audi can actually make a large twincharger for the S4/S5. 3.0 V6 82.5x92.8, with the new TVS supercharger (quad lobe) that primes the two turbos, no torque latency.
        Somethng like 350hp/350ft-lbs, to match BMW's N54.
      • 7 Years Ago
      Personally, I'd like to see Audi put a high performance diesel into an S or RS car. Bring us LeMans tech for the road! 400HP/700ft lbs and 30+mpg or something else impressive... I can dream...
      • 7 Years Ago
      I'm really looking forward to Lambo's future models. The Reventon is wicked and Embolado looks crazy too. Italian madness and German engineering, the best breed of cars.
