This is a simple exercise. Just by looking at the current range one can predict what will arrive in Europe and what not (or better, what should not).
G35: YES, of course. But with diesels
G35 coupé: YES, of course!
M35/45: Maybe, but needs a redesign to comply with European tastes. And diesels, of course.
Q45: errrr..., no.
FX35/45: YES, PLEASE! However, don't forget the V6 diesel.
QX: NO! Please don't.
Technically the biggest changes are related to engines. The wonderful Nissan V6 will be present as well as in some Renault vehicles. The current Renault diesel 4-cylinder engines can be used in the G-sedan, both in 2.0 and 2.2 versions. However, a new diesel V6 must be developed by Renault. The current offer originated from Isuzu is not adequate.
Future vehicles? Well, it is a bit early for that. One can expect that Infiniti range will develop with some European-only models. Possibly some smaller SUV based on a future (Nissan Qashqai) Renault model… but don’t be afraid: Renault will not exercise badge-engineering in its cheapest way! The technical expertise and practice of Renault is too good for that.
FX in Europe? Yes, please!
