i would say that this current gen is either a gen 3 or a 4.
gen 1 had no roof, no side windows, came in convertible only.
gen 2 had the slightly bigger engine, and the fixed dual bubble roof with the exhaust coming straight out the back vs out the sides like in gen 1.
gen 3 was totally redone where the hood opens in the conventional way vs openning up like a clam shell, the exhaust now comes out the sides again but with a cross over pipe to make it sound better, redone interior etc etc.
gen 3.5 or 4? it has the new 600 hp engine standard.
so i would say its either a gen 3 or a gen 3.5 or a gen 4 for the current viper.
as you can see i'm a car enthusiast, i love all cars the same and i love the study their design and differences and their evolution and i do love the current trend of cars with integrated rear bumpers, headlamps and small green house.
the most outdated thing about our nsx is the shelf rear bumper, and the rear taillights where the lens is not clear like the modern cars where you can see the designs in them.
i love the viper, the last gen 3 i drove scared to shit out of me, it really did feel too fast for the streets but my friends 500+whp supra didn't feel quit as scary. hmmmm
i love the z06 and i would like to own one someday but i also love the 02+ nsx. if only my car had an extra 50 or hp it would be perfect. i'm looking for 110-112mph trap speed n/a. that would be just perfect.
