Looking forward to the Inifinti Q50 Aue Rouge concept and I can't say I know for sure, but we all know that Benz/Infiniti are going to be sharing engines and platforms, and we know the new C-class C400 has a twin turbo 6 with 330hp/360tq ... I would venture to say that a educated guess would be expect this 3.0 ltr (can't say I've read V6 or inline 6 though, I assume V6 but the insider news indicate a inline 6 is again in the drawing board for Benz eventually) to be in the Infiniti concept and would make sense to drop this into the new Z as well...
I'm sure Benz will have a 3.0 base motor and probably a higher displacement version too (in the 400hp range)... I'd say 400hp in the Infiniti but only the 330hp version for the Z with the higher one for a Nismo version..
Anyway just guessing but if you follow the industry you notice trends and what happens out there usually follows these trends... This just feels like a likely outcome
