The new Acadia has the same wheelbase as the Terrain, is only marginally longer, the third row seats are now optional, and has a base 4-pot and optional V6. Sooo.... Where does this leave the Terrain?

My only guess would be the Terrain will get downsized to fit more in line with the Escape and similar given it’s always been a ‘tweener between two segments. Interesting choice, GMC.
