Acura has only just lifted the veil off its (production) NSX supercar, and digital photo manipulators are hard at work creating new versions based on it. X-Tomi cut the top off the NSX and called it the Targa – it looks pretty clean, and the design itself is next to identical to that of the coupe.
Honda’s own effort to make a topless NSX would probably be very similar if not near-identical to this – there would be no reason to change more and the design does look as if it’s been done with a removable roof in mind.
It could, however, end up being completely different, if the version you saw Tony Stark driving materializes. It’s more of a conventional roadster than a targa top like this rendering.
Talk of a drop top is still premature, though, as we’ve yet to even learn the specs of the NSX. Besides, as is the case with all modern supercars in the same vein as the Acura, ditching the roof has minimal effect on stiffness.
