That rear seems like a waste of effort . I have never thought that the rear end needed to be changed. Perhaps the front would benefit from a modernization, but the rear? I think this is someone’s photoshop.
Welcome back to 2018. We've seen this design before.
I recall how the original NSX changed over the years. From 91, the only change I recall was the 93 with both passenger and driver airbags, 95 got the Targa top and newer wheels?, 97 was the biggest change where we got the 6 speed trans replacing the 5 speed, the bigger brakes, the the increased displacement of the engine improving torque and horsepower, the changes in emissions to support same, I think the 2001 got a better ABS (not sure when it came into being) then 2002 dropped the popup headlights and changed the front and rear facia and added the facia on the doors, changed the hood, changed the interior to add gray stitching on the seats and dash and doors and steering wheel. The infotainment system never really changed. When you look back you can see that not a lot of changes occurred compared to the years of production.
