Next Z to be unveiled in 2013 Tokyo auto show.

well last months was a let down for the car that was "supposed" to show up, so yes hopefully the new Z arrived at Detroit, but also I think Nissan should be releasing the new Maxima and Murano soon, don't know if they'd do more than one major reveal per show? Who knows...
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
