The images you see below are the updated version of the Buick LaCrosse, which was first launched way back in 2009 as a 2010 model. This model proved to be a hit amongst China than America, and so today we are not surprised to see the updated version spotted first in China, than U.S.
General Motors had announced about this car, along with other 8 new models, in September 2012, so this was totally expected.
The model which will be launched the States will be known as 2014 year model, and is likely to carry the same front grille and revised headlights with LED accents, but at the same time nothing can be said that whether the xtra chrome at the back or those strange vents on the hood near the door pillars will remain the same. If you look at the pictures, it does show us the interior, which is better than the 2012/13 LaCrosse, featuring revised door trim, a big display and even a starter button.
Additional details will be soon posted, until then stay tuned for more updates.
