I leased this 2017 GMC Terrain awd gas millage says 23 to 28 mpg I'm lucky to get 19 mpg it really gets about 18 on highway and 15 in the city, my parents retired from GM, and i would never recommend a terrain to anyone GM really got this one wrong, and if you use the eco boost on the highway the transmission shifts very bad all in all not worth 30 grand, plus add 30 percent more in gas cost.
