"We had originally targeted deliveries by the end of 2015," wrote Jessica Fini, an Acura spokeswoman, in response to a query. "So the new production/delivery timing is slightly later."
Fini said the car is expected to begin arriving at Acura dealerships in the spring. She said it does not yet have an official model-year designation.
The new NSX marks the first return of the model since the original NSX, which was produced from 1991-2005. Unlike that car, the new NSX features a hybrid powertrain, a twin-turbo V6 and all-wheel drive.
Pricing has not been announced, but it is expected to carry a price tag of around $150,000.
The NSX was on display at last weekend's 2015 Pebble Beach Concours d'Elegance.
Acura said the car will be available with a number of factory options. They include a carbon exterior package that bundles a front spoiler, side sills and rear diffuser.
An interior carbon sport package features a carbon-fiber meter visor, steering garnish, aluminum footrest and sport pedals. A nine-speaker ELS Studio and Audio package adds entertainment and navigation amenities.
Exterior colors include Valencia Red Pearl, Nouvelle Blue Pearl and Berlina Black.
Edmunds says: Car shoppers who have been anticipating the showroom debut of the all-new NSX will have to wait a bit longer.
