Nissan 450Z Coming ?

Some confusion about the next flagship coupe in the european Nissan lineup.
Is the new GT-R coming to Europe too ? Or is there some truth to the Autocar rumours about the Nissan 450Z ?The 450Z should be an evolution of the current 350Z, with a sporty version of the 4.

5 liters V8 engine mounted on the Japanese Nissan Fuga and on some Infiniti models in the USA, tuned to deliver about 400 hp.

The only problem is that this engine doesn’t satisfy Euro 4 emission regulations, but this will have to be remedied anyway, since Nissan wants to bring Infiniti to Europe.

The body should remain relatively unchanged, while the 450Z might have a 4WD transmission.
The main question is: can the Renault group manage in bringing back to life the Alpine brand, bring to market a Nissan rival for the Porsche 911 and introduce a new brand in Europe to rival BMW & Audi ?
