Based on Nissan's 350Z this mat black mule was driving its first rounds on the roads when our spy photographers managed to snap some pictures of it.
Is Nissan planning a 400Z? (Automedia)
Looks wider and slightly longer and we can clearly see that the headlamps don't really fit. Alongside the mule Nissan had a current 350Z and a Porsche Cayman S to compare with.
At this stage it is still too early to make any comments about how the finished car will look like but we can be sure they will add some serious power and hopefully make it a little lighter to improve the handling.
Rumours in Japan say the new name will be 400Z but we will have to wait and see for that.
