I'd been told the RS5 is normally aspirated.

Pictures from Audi showing an 8500 rpm red line suggest the same.

Its an evolution of the RS4 V8, Arguably R8 V10 engine with two cylinders lobbed off.

Why would they use a different motor to the RS4 confused

Why well firstly that design is 3 years old, end everything moves on, secondly RS5 is B8 platform and RS4 was B7, and perhaps most importantly. Because this time they are claiming 450bhp, last time they were claiming 414 or 412 or somthing and they all only made abour 380.

SO it must be a different engine (even if it turns out just to be manifolds, cam profiles, ets and basically the same lump) to get the extra power.
