Why it stands out

The 2018 GMC Terrain is noted for its spacious interior and multiple engine options, including a turbocharged 2.0-liter engine that provides a substantial increase in horsepower and performance. While it attempts to improve upon the previous model's design, many critics argue that it falls short with a less rugged appearance and mediocre safety ratings. Inside, the Terrain is equipped with an advanced IntelliLink infotainment system, offering modern features like Apple CarPlay, Android Auto, and a robust sound system. However, its value compared to competitors is questionable, particularly given the high price tag and lower cargo capacity relative to rivals like the Honda CR-V. As such, while the Terrain has its merits, depreciation of style and performance raises questions about its overall appeal.
