We thought throwing a detuned version of the Lamborghini Gallardo's V10 in the Audi S8 and S6 was a brash move on behalf of Ingolstadt, but news from World Car Fans is that the next RS6 will receive a turbocharged version of the 5.0-liter V10 producing between 520 and 550 bhp. We previously thought the RS6 may get the Q7's top petrol engine, a 4.2-liter FSI V8 tuned to 500+ horsepower, but it would be strange to give the top A6 model two less cylinders than the S6. Still, this V10 makes 520 horsepower without the help of a turbo in the Gallardo, so it still seems strange to detune the engine and slap a turbo on it to increase the power back up to a level that can compete with the BMW M5 and Mercedes-Benz E63 AMG. Either way, Lamborghini can't be pleased that a high-performance saloon and wagon from Audi will soon be pumping out more power than its entry-level exotic supercar.

      The VR6 is an approximation of an inline6, the W12 is an approximation of a V12, turbine smooth would not be the right adjective.
      Audi more than likely need compatibility with automatic transmissions, so input speed can't be ~8000+rpm, it needs to be ~7000+rpm.
      The 5.2 V10 is the standard corporate engine bore/stroke 84.5/92.8, only 5.5mm between cylinder=no turbocharging.
      So the 2mm smaller bore works with turbocharging and the automatic.
      The lamborghini V10 is very tractable. It has variable resonance and a dual length intake manifold, it is all bottom end compared to the M5(that is why it has 7 speeds)
      The souped up V10 makes the same peak torque 376ft-lbs (at a lower engine speed no less) and raises peak power to 512hp@8000

      Adding turbo's makes sense to me (my $0.02)....boosting low end torque is a huge + in my book :)

      What JonnyV said.

      The NA v10 probably is a tad peaky, which is quite acceptable in the lambo, being a supercar with hot blood and all.

      A more conservatively tuned camwork with a smallish torbo would make this thing a real rocket (350 lb/ft torque fron 1000 rpm all the way to 8000) From 0 to licensed revoked in 3 sec!

      And listening to M5 criticsm the BMW v10 is not exactly a bottom end torque champ.

      Why on earth would they use a 420bph V8 in the R8, the supposed cream of the Audi R* crop, when the S8, S6 and now RS6 include a larger motor with more horsepower?

      I'm still scratching my head as to why the same V8 in the RS4 is found in the R8. That car should have a hyper-tuned version of the V10 at the least.

      A bit odd I guess, though the turbo is there probably for some extra low-end grunt. Looks sexy, though :)

      I happened upon an S6 at my local dealer while my A4 was getting new wiper blades (free maintenance). I was struck by its' 435HP V10 with a price tag of $78K. The RS5 is gonna cost a mint!

      W12 would be too heavy. I have a previous gen rs6 and with a big heavy bi turbo v8 there is a bit of understeer, even with quattro. the v10 they are using is actually relatively light in comparison, and as audi are now splitting the power 60/40 in favour of the rear tyres that should be a good balance. Time to trade!

      Chris, a version of the V10 is definitely coming to the R8. The R8 is directly based on the Gallardo and they already plan to turbocharge that to raise horsepower to 600 hp to make it distinct from the V10 that is offered throughout the rest of Audi. The question will be will they offer a turbocharged V10 in the R8. They could if they held back just a touch. Say 560 hp. There are people who would pay more for the Lamborghini skin and 40 extra hp rather than the R8. I am slowly coming to the conclusion that the R8 could become an iconic car, with a level of respect reserved only for the 911.

      Well, the S6 already makes 398 lb-ft of torque, the turboed version of the same engine is guaranteed for over 500 lf-ft of torque (525-550 lf-ft of torque is likely.

      You don't want a W12. That is an extremely heavy engine. Notice the V10 FSI produces as much power and torque as the W12 - and it's much lighter, and much more compact.

      Nice and stealthy!!!! I'd sell a family member to a sweatshop in Bolivia for one of these.

      "I'm still scratching my head as to why the same V8 in the RS4 is found in the R8. That car should have a hyper-tuned version of the V10 at the least."

      Maybe if you drove an RS4 you'd know what the hell you were talking about. It's fun to read these idiotic puntitry comments though from people who like to tell Audi how to run their already amazingly profitable business and yet seem to have no wheel time behind their current top of the line vehicle.
