Initially due to arrive by 2009, increased emphasis toward new hybrid models and the launch of the GT-R have delayed its development.
Boasting the brand's 3.7-litre V6 engine from the Infiniti G37, power is expected to rise by at least 20kW to more than 246kW.
Its namesake will also be derived from its engine displacement much like its predecessor, with the new model likely to be named the 370Z.
Currently this replacement model is due to be released in 2010 as a 2011 model boasting an evolutionary new design.
From these images we can see the new model will largely retain much of its proportions, and feature much sharper 'whisp' head and tail lamps.
Disappointingly it does not appear that the new model will adopt the flush GT-R style door handles but rather maintain the awkward oversized vertical handles from the 350Z.
