Similar to what GM has been using for years...

My information says that it's very posible for a V8 4.2 TFSI. So RS4 engine with a turbo - 590 HP / 750 Nm.

V10 5.2 has problems with overheating (with installed turbos on it) so the only variant of this engine is N/A version. That's also posible.

Or like as I said: V8 4.2 TFSI. But in my opinion, it should get two turbos (twin-turbo). Smaller one for low rpm and the big one for high rpm. That would decrease turbo-lag and increase output horsepower.

We'll see...

So have they made the presentation timeline shorter because some sources talk about next September (IAA)?

Here is CAR Magazine's take on the upcoming RS6:

Seemingly not… Audi’s piping hot RS6 – caught here undergoing its final rounds of Nürburgring dynamic tests – takes the 429bhp 5.2-litre V10 from the S6 and bolts on not one but two ultra-responsive turbos for a headline-grabbing 530bhp. That’s a 43bhp more than BMW’s M5 and 16bhp more than the Mercedes E63. Who said the horsepower was dead...





True, we thought the S6 was a bit low-key and subdued, but don't forget that while Audi’s S models are engineered and developed inhouse, RS models are the work of quattro, Audi’s independent tuning house. And as we experienced with the RS4, the go-faster gurus at quattro know all about driver engagement and scalpel-sharp dynamics.

Which is why this oddly – and rather effectively – camouflaged RS6 mule was being hammered mercilessly around the 'Ring.



Under that bonnet, the direct-injection bi-turbo V10 features heavily revised intake and exhaust systems to deal with the lower compression ratio and higher charge pressures. While the power output climbs a modest 100bhp over the S6, those two turbos will be used to bolster the V10’s torque curve. Expect at least 500lb ft of twist action for searing acceleration in any of its six gears, resulting in a 4.5 second sprint to 60mph and an effortless 155mph limited top speed. Derestricted, the RS6 would easily hit 200mph.



Both RS6 models will feature an advanced aerodynamic package. Look carefully at the rear of this mule and you can easily make out a ground-effects rear diffuser, employed to suck the car closer to the road as speed rises. Factor in the same intuitive quattro four-wheel drive system seen in the RS4 that favours the rear axle, tweaked steering and vast carbon ceramic brake discs at each corner, and the RS6 should be at home on any road, irrespective of weather conditions.

While the previous RS6 used a relatively simple closed-loop adaptive damping system, the new model is expected to use a heavily uprated version of the new TT’s adaptive magnetic damping system. Using a magneto-rheological fluid, which alters when a voltage is passed though it, the dampers will offer the kind of instant reaction to keep the big Audi’s body movements in check. Roll on September for a titanic Audi RS6 Avant, BMW M5 Touring and Mercedes E63 Estate battle.

wow damn is the whole greenhouse in CF?

the rear treatment looks hot..
this car will be da bomb..
but so damn expensive..

Can't tell much from the pictures, but the engine should be very good, makes the M5 look a bit weak on toque.

The overheating problems have been now solved according to some Fourtitude members. Also a 530 bhp output is rather low for a twin turbo V10. If (notice that i use "if") the RS6 has a bi turbo don't expect anything less than the rumored 580 hp.

LISTEN TO THE NEW AUDI RS6 BEING THRASHED AROUND THE RING!

Car & Driver

Gorgeous deep throaty sound.

Sounds like a V10 engine....a Twin-Turbocharged V10 engine.

That picture isn't even the RS6 with all the bodykit and still looks hot, can't wait for this car to come out, have a thing for RS avant cars!
