Low-poly texture without shading

Im working on a low poly game, but the only problem is that unity shades every single poly with light and make it looks like a very bad attempt at making nice looking low poly car, Id like every polygon to have only 1 texture on it. eg: http://www.awwwards.com/media/cache/gallery_two_columns/awards/images/2013/02/low-poly-timothy-reynolds1.jpeg , but unity keeps making my mesh look ugly ! what do I do? thanks!

If you search for “flat shading”, you’ll see this has been asked and answered many times; you either need to manually duplicate each shared vertex in your modelling program, or let Unity do it on import by setting the smoothing angle in the mesh import settings to 0.
