Ford has officially unveiled the 2013 Mustang at the 2011 LA Auto Show, complete with its new nose. The design incorporates a more upright, prominent grille with redesigned fenders and a hood to match. Speaking of the hood, GT models feature functional heat extractors to keep the engine bay as cool as possible. That’s a good thing considering that the 5.0-liter V8 now produces 420 horsepower in the GT and 444 horsepower in the Boss 302. Inside, drivers can take advantage of the new TrackApp technology to keep an eye on quarter-mile times and the like, and those buyers who opt for the automatic and now select their own gears through new paddle-shifters. There’s also a set of trick new LED taillamps out back. Funk Flex
