470 hp from 4.2 liters?
Not without forced induction on a road going production car.
That would be an amazing 112 hp per liter NA
My guess it IS a tweaked version of the 4.2 liter in the RS4 but expect it to be in the 430-435 hp range at most.
Add that to the lighter RS5 platform and it would make it a pretty quick car.
A TT V10 just won't sell very well here in the states, would make the car too front heavy as well.
However, two small turbos on the 4.2 liter making 5-6 psi boost would make that one heck of an engine and car.
But I'm sure it would require the lower revving 4.2 from the old S4 and current S5.
That would put it in the 450 hp range and a boatload of torque which would be awesome for that AWD platform.
