The 1st Gen Acura NSX would receive its first major evolution in the form of a Targa-like removable roof-top for model year 1995. These cars are commonly referred to as the NSX-T. It continued to be powered by the all-aluminium 3.0 L V6 engine (C30A), in either automatic or 5-speed manual, common to the NA1 models. Model year 1997 would see the introduction of the NA2 models, overlapping with some NA1 models that were sold into 1998.
