AutoWeek has spy photo of front engine V-10 NSX replacement mule based on S2000:

Next NSX? - AutoWeek

Drift much with that thing?

 

I heard that they might make a replacement type of s2000 that would be a 4 door non-convertable out in a little bit. I would think that even if they were testing a V10 only, that they would test it in something bigger in shape than a stretched s2000. I'm betting on the 4door s2000.

Edit: Temple of Vtec has a link to a video of it running. Suspected 5.0L engine quad exhaust, 550hp, and above 200mph top speed.

 

S means two doors, two seats, and convertible; it has since Honda first put a second pair of wheels on a vehicle in 1963.

You can bet on a four door S2000 but be aware that the Vegas odds are roughly zero.

"Honda XGA
A new type of sports car.
The internal name given to the S2000's replacement is XGA. We had thought all along that the XGA would be a 4-door sports car showcasing Honda's SH-AWD system used in the RL and its advanced hybrid technology (remember the Dual Note concept car?). Well, now we're hearing the company is leaning toward producing a coupe based on the RL platform, but equipping it with either the V-8 or V-10 for the NSX replacement.
Honda will surely equip the luxury coupe with its SH-AWD system, creating a car that would match up with the likes of the Nissan GT-R. If the XGA and the next NSX make it to production as we foresee, it would mean that all of Honda's sporty cars would be awd. Could Honda be trying to redefine the classic sports-car formula, and change the way we think about sports cars and awd? It's a definite possibility because Honda has expressed that much confidence in the capabilities of its SH-AWD.
The XGA will be front engine and look quite different from the RL, and it may go head-to-head with the GT-R. A hint of its styling may be seen in the Sports4 Concept shown at the Tokyo Motor Show.
While it's still too early to tell when this car will be available, we're sure that Honda is hard at work to reestablish its image as one of the world's leading sports-car makers. It shouldn't be long after the end of the S2000's run that we'll start seeing exciting new stuff from this technology-driven company."

They make it sound like the 4 door s2000 concept (XGA)would become the next "NSX" replacement and not a direct NSX future model. Maybe its best to leave the classic NSX alone and make a totally new ledgend.

 

1. No four door car is going to replace the S2000. The S name has, again, meant something specific to Honda for over four decades.

2. The XGA is an April Fools joke from 2006.
