New details of the upcoming 2013 Ford Mustang GT include a new pony-badge for the storied muscle car.

These are the latest spy shots of the upcoming 2013 Ford Mustang GT.

New on this prototype is the front fascia where the fog lights have moved from the grille down to the lower front bumper fascia and the historic pony emblem has slid on over to the driver's side of the grille onto a red, white and blue striped badge.

The headlights too are new and feature some LED piping. There's also a GT500-like front lip spoiler and a grille opening.

At the rear there's a new trunk-lid-mounted wing and a revised bumper.
