After languishing in mediocrity for far too long, the 2013 Chevrolet Impala can't come soon enough, and our shooters managed to snag a camouflaged prototype – both inside and out – for the first time.

Based on the long-wheelbase version of the Epsilon 2 platform, the reimagined Impala is set to be powered by a choice of either GM's 3.6-liter V6 or its recently revealed 270-horsepower, turbocharged 2.0-liter four-cylinder. An eAssist version is also likely to be offered soon after its debut.

Inside, we get a glimpse of a reworked interior that's more plush than the current model, complete with leather dash and trim, tasteful aluminum accents and a sizable nav screen front-and-center.

The exterior is harder to gauge, but the ride height is noticeably lower, the roof and windshield more raked and the front fascia has taken on a pointed, Camaro-esque shape. We should know more in the coming months before Chevy takes the wraps off in the first half of the year.
