Why people love the 2021 GMC Terrain
The 2021 Terrain's 1.5L turbo engine paired with its 9-speed automatic feels quick off the line without draining your wallet at the pump, especially in city driving where it averages mid-20s mpg. Owners love the straightforward cabin layout—physical knobs for climate control, no buried menus—and the high seating position makes parallel parking on narrow streets feel less like a guessing game.
