When Honda unveiled the Advanced Sports Car Concept earlier this year, it said the vehicle was a direct preview of the 2008 Acura NSX. Typically automakers don't say which future production cars ambiguously named concepts are supposed to represent, but Honda officials had no problem disclosing their intentions for this project.

Now it appears the car might be headed back to the drawing board.

Although it wasn't slammed by the automotive press or enthusiasts, the concept didn't get rave reviews, either. It turns out Honda executives were hoping for something more breathtaking, too. As a result, they've asked the design team to rethink their plans, according to a report by Winding Road magazine.

While the basic proportions, V10 engine, and all-wheel-drive will stay, the rest of the package will likely change before production begins in early 2008. Look for the production version of the new NSX will arrive at the Tokyo Motor Show this fall.
