The third teaser image reveals door-mounted side mirrors and wrap-around taillights. Chrome is used liberally to trim the window line, and we now see a soft character line running down the side, through the door handles. The fourth adds to the picture with the front end--much of which was already seen in the head-on teaser below.
Aside from those few details, Buick has also divulged that the Encore will be a five-passenger crossover, feature "QuietTuning" technology, and will offer a similar feature and options package to current Buick vehicles.
As lead-up to the Cobo Hall introduction of the Encore, Buick will be drip-feeding us a photo each week until the show on the Encore tab on its Facebook page, too, so head over there if you want to stay on top of the Encore's (gradual) arrival. There's just one week--and one photo--left.
