It may seem like just yesterday that the 370Z replaced the 350Z, but it's been three years--time for a mid-cycle refresh. For the 2013 370Z, it's a very, very mild one, as revealed today at the 2012 Chicago Auto Show.

The most noticeable changes are the removal of the controversial "fangs"--small bits of bodywork in the grille--that made the 370Z look angry to some, and the addition of LED daytime running lights. To some eyes, removing the fangs brings the 370Z closer to a resemblance with the 350Z, though it retains the hook-shaped headlights and taller hood. Whether evoking the 350Z is an improvement depends on the viewer.

Out back Nissan has replaced the black piece of plastic between the tailpipes with a red reflector. Why it wasn't a reflector from the start, we'll never know. But at least the awkward piece of plastic that clashed with certain colors is gone.

The wheel design has been ever so slightly tweaked, with a more offset appearance. While 18-inch alloys are standard, 19-inchers are included in the Sport Package.

Take a look through the live photo gallery below, and for all the details regarding the refresh, check out our preview post right here.
