Perry is right. In terms of platform sharing and technology overlap, Honda has plenty to draw from to keep costs down.
The NSX chassis/suspension is so well tuned and designed that it can be continued with a few weight-saving tweaks here and there.
The J-series V6 is now a well-developed power platform that is compact, fuel-efficient and reliable. If Honda gives it the C30A treatment (DOHC, titanium rods, 6-bolt mains, ITB or revised induction, 8000rpm valvetrain), the 3.7L can deliver 300-350 reliable whp easily.
There never was anything wrong with the NSX 6-speed, so that can be re-used, or the 6-speed (with different gearing) from the new TL-S, to save money since it already matches up with the J37. For the bling factor, offer a F1-style semi auto as a $5000 option...maybe import the stillborn ASCC V10 box since the R&D is already done.
The body is just sheet metal. Honda can stick with aluminum or use steel/carbon fiber to save $. Use the HSC as a base and work in the classic NSX design cues (side vents and integrated rear spoiler). Some folks on this forum have already done so with impressive results.
Honda can also use the HSC as an opportunity to update known NSX issues, namely the brakes, oiling system and interior.
Using all of this existing technology, R&D can be kept to a minimum but still produce a car that will drop jaws with its looks and be competitive on the road course. Nissan did it with the GT-R (except for the looks part lol), so Honda certainly can do it with the NSX.
The idea of a $200k V10 hyper-car is just ridiculous from a marketing and sales standpoint, especially in this economic climate. But, there is still a sports car market out there to be tapped. People are still buying Corvettes, Caymans, 911s, Shelby Mustangs, M3's, etc. That should tell you where the sweet spot is - $50k to $75k, which incidentally is right where the original NSX was aimed. Bring in a 300whp J37 modernized NSX at $60k and it will move units because it will accomplish what the original NSX did - VALUE. You get a whole lot of car for less money. That sells cars. People stopped buying the NSX because at $90k it was no longer a value. They started buying the C5 Vette instead because it was.
After the initial marketing splash, do a 320whp Type S the next year at $65k and then a balls-out 370whp Type R at $75k to satiate the mag racers and Best Motoring fans. Do the typical Honda 4 year refresh, keep the prices firm and watch them roll off the line.
You can even keep the green marketing strategy. The J-series is a very efficient engine on the low cams. Hell, you can show the NSX tearing up Suzuka, "0-60 in 4.5 seconds" and then show it quietly cruising on the highway "30 mpg". "Who says you can't have your cake and eat it too? The new NSX, from Acura. Advance." There you go, free commercial from me.
And/or make it E85 compatible. There is money to be made here. Ugh, it's so easy... like throwing darts at the side of a barn, come on Honda, wake up!
