The design is an evolution of the current model's silhouette, which smoothes out some of the coarse lines, sharpens the headlights and adds more pronounced wheel arches to accommodate a wider track. Within those wheel-wells, expect to find a slightly softened suspension that will give the new Z a more forgiving ride, hopefully without losing its tarmac molesting abilities. Hopefully Nissan will be careful not to add too many pounds in the process, as the Z car is not known for being light on its feet.
Much like the exterior, the interior will benefit from a few focused design tweaks, mainly centered on ergonomic and material improvements, with the addition of more storage space and, generally, a more refined cabin.
Since the VQ35 3.5-liter V6 remains one of the most capable sixes available, the only change that will take place under the hood is an increase in power, upwards of 325 HP, while still retaining its beefy torque curve.
Edmunds speculates that the new Z will make its debut at dealers in late 2008, as a 2009 model.
