It appears as if we can expect to see the 2013 Lincoln MKZ borrow some from the just-shown 2013 MKS and MKT. Lincoln flashed a quick teaser of an unidentified vehicle's nose at the 2011 LA Auto Show, and it appears to be the face of the new MKZ. The teaser flashed in segments across the backdrop of the Lincoln booth as designer Max Wolff spoke about the 2013 MKS.
If that's what it is, the sedan looks to wear a similar split grille with integrated headlight housings as its larger siblings. Designers have opted to grace the smaller sedan with fewer, horizontally oriented grille slats in place of the vertical pieces of the MKS, and the grille outline itself seems to have more careful detailing, as do the slats themselves, which appear to have varying surface treatments. We've heard a lot of scuttlebutt about the MKZ looking stunning and showing off Lincoln's bold new design direction (as opposed to the light refresh jobs revealed in LA), so perhaps this partial view is a bit misleading.
Wolff said that the company has more design news in store, and that we'll all see the first examples debut at the 2012 Detroit Auto Show in January. You can hit the jump to see the full press presentation for yourself (the teaser comes at about 2:40).
