2009 Audi RS6 - Click above for high-res gallery

The next generation Audi A6 is expected to debut early in 2010 and that means a new performance S6 and super-performance RS6 will likely follow a couple of years later. As improved efficiency and reduced CO2 emissions take hold in the early years of the next decade, that almost certainly means the S6/RS6 will follow the trend of this year's new S4 and down-size its powerplant.

The larger RS6 is currently propelled by a twin turbocharged 5.2-liter V10. The V10 which is shared with the Lamborghini Gallardo (in normally aspirated form) will likely give way to a smaller, boosted V8 that should be lighter and more compact. In all likelihood, the smaller engine won't result in a reduction in performance and will probably be in the 4.0-4.5-liter range with either supercharger, turbos or perhaps both. Recent rumors have indicated that the next M5 will follow the same path taking on the 4.4-liter twin-turbo V8 from the X6 M.

      I was at the Moto GP in the summer and they have an X6M (V8) and an M6 (V10) as safety cars, listening to them lapping the track there is no contest, the V10 makes the V8 sound like a prius, couldn't give a monkeys if its just as powerful or not, if I'm spending that sort of cash I want all that noise as well.

      I know VW/Audi has experience with a twin-charger setup and if Audi really wants to emphasize "Vorsprung durch Technik" in this segment it may be a wise move. Downsizing the motor from a V-10 to a more compact V-8 can leave enough room necessary to fit what could be a very innovative system.

      I'm all for a V8 - if it's faster and gives the car better handling.

      It's been rumored that Lambo are considering a new entry level 'baby Lambo' - maybe that would use a V8... and maybe Audi could use it in it's bigger RS models to keep that tantalizing Lambo performance connection.

      And an AMG V-8 6.2 makes the M6 sound like a rice rocket.

      Okay maybe not, but you can's possibly believe that a V-8 couldn't sound as good. Look at GM, Ford, Chrysler, Mercedes, Audi, BMW (E39 M5 much?), Jaguar, and others for proof of that.

      Give me the next M5 anyday!

      I don't really see why not. The burble of a V-8 is nothing other than iconic, even for the Germans. Audi/VW makes a fantastic sounding 4.2 V8 so I don't see the problem. Maybe a 4.5L+ however. Audi purists will balk at the following: I think they should really consider supercharging it like the new S4. You get naturally aspirated V8 crushing torque and fat bands of power and torque. The latest superchargers are very efficient as well. Like the regular and S version of the blown V-6 they should try to mute the sound of the blower, however.

      I'd really like to have both engines available, but I guess the V8 will be fine. After all, that block from the X6 is a beast. This is still gotta be my favorite sleeper.

        Look at all of the turmoil caused by a simple "outdated" pushrod motor. Those pressurized LS motors still gives you more bang for the buck. Can't wait for GM to add DI to the LS line. More powerful, more efficient in a smaller, lighter package. Damn pushrods.

      I love Audi to death, but how about dropping some weight?

      That prototype A/S5 is down 800lbs. Imagine what that could do to the RS6!
        • 5 Years Ago
        Yeah...like a $20K carbon fiber hood ala Shelby Cobra mustang!!! LOL!
      • 5 Years Ago
      Well, it's a Lamborghini engine, so my feelings in favor of downsizing otherwise are effectively negated.
      • 5 Years Ago
      Go twin turbo V8 like the old RS6!
      • 5 Years Ago
      It's funny to hear people complain about engine downsizing in other posts (not yours Jeremiah), when in reality they often get more power/torque in a lighter package that also results in better handling, performance, and better gas mileage.

      Not that I'll ever own a RS6 like this, but it makes me happy for sure!

        I am of the opinion that a V10 in the RS6 and M5 was a bit overkill. Boosted V8 should do the job just fine.
