It's been almost two years since we first saw the 2011 Alfa Romeo 4C Concept, but the sporty coupe looks like it's getting its final touches before going on sale – including in the US – at some point this year. Judging by these spy shots, the production 2014 4C will retain many of the concept's styling cues, although we can also spot a few changes.

While the prototype seen here is still wearing heavy camouflage at the front and rear, we do see that the sides of the 4C have received some significant changes. For starters, the doors are much smaller, cutting into the side vents less, and there are also visible handles and production-look side mirrors. As promised by the teaser image released last year, the coupe will continue to ride on the unique circle-spoke wheels.

The return of Alfa Romeo to the US market has encountered a few delays over the last couple years, but it sounds like the 4C could be the first of six new Alfa Romeo products on our shores by 2016.
