Nissan? I was just looking at the new Altima, where the specs indicate the use of a VQ35 motor and the "same multi-link suspension as the new Z". This would certainly reduced the cost of the new Z if more components are shared with other Nissan vehicles. That would be in line with their new mission of sharing more platforms and reducing production cost. So, I would expect the new Skyline and new Maxima will use the Q45 V8 motor.
