Tony is basically correct. Beginning in 1995, over 98 percent of the automatic NSXs sold have been the NSX-T (removable roof panel), which is heavier than the '91-94 NSX Coupe with the fixed roof. I've never seen any tests for an automatic NSX-T but I would expect 0-60 time to be about 0.2 second more than an automatic NSX Coupe. One of the rare '96-01 NSX Coupes with the automatic should perform the same as a '91-94 NSX Coupe with automatic.
