Not much is known yet. But being based on the same platform as the Maxima, it will use its 3.5 Liter V6 and CVT.
I have to say that from experience, I think the CVT in the Maxima is vastly superior to the 7 speed auto in other Infiniti models.
So this should be pretty good.
The interior seems much closer to the Infiniti M than the Maxima as well.
I think, it priced right, this will be great competition to the Buick Enclave and Audi Q7.
