It hasn't been making the speediest trot to production, but the all-new Acura NSX is finally rounding the corner toward the finish line. Acura announced this week that the production car will debut at the North American International Auto Show, the same venue where the concept version first premiered three years ago.

As far as teasers go, the four photos Acura released are fairly revealing. From what we can make out, the production NSX stays quite true to the concepts from the 2012 and 2013 Detroit shows, featuring the same sporty, mid-engine profile and Acura's signature central-crease styling. The headlights appear to be opened wider and cut in width, and a more traditional grille design sits between them. There are also some pretty serious new vents on top of the front fenders. The rear includes a prominent deck lid spoiler and appears to be a tad more concave in parts.

Overall, it looks like the production car should incorporate everything good about the concepts with a few interesting modifications. Of course, we won't know for sure until Acura fully reveals the car on January 12, the first media day of NAIAS 2015.

"After three years of intensive development work we are excited to reveal this next-generation supercar – the Acura NSX – to the world," says Ted Klaus, chief engineer and global project leader over NSX development. "We've developed a human-centered supercar that responds to the will of the driver and that builds upon the NSX heritage."

Acura's press conference should also provide the first real details about the NSX's engine, performance and equipment. Acura has said all along that the car is powered by a mid-mounted engine + three-motor hybrid system, but outside of that, nothing's certain. Acura's teaser video below sounds off with a first listen of the twin-turbo powertrain.

Gizmag will be on the floor of NAIAS bringing you news of the new NSX and the other major debuts of the show. In the meantime, spend a little time comparing the teaser photos of the red production NSX to the concepts of the past in our gallery. Let us know if you find any other major distinctions.
