The GMC Terrain II, specifically the 2.0-liter (252 hp) AWD Start/Stop Automatic variant, represents a significant step in GMC’s compact SUV offerings. Produced from 2017 to 2020, this version of the Terrain (internally designated as the second generation) aimed to balance fuel efficiency with respectable performance, appealing to a broad segment of the North American SUV market. It was positioned as a mid-range to upper-mid-range trim within the Terrain II lineup, offering a more powerful engine option than the base 1.5L turbo while remaining more accessible than potential future, higher-performance trims. The Terrain II, built on the GM Theta platform, was intended to compete with established rivals like the Honda CR-V, Toyota RAV4, and Ford Escape.

Powertrain & Engine Architecture
The heart of this Terrain II variant is the LTG 2.0-liter turbocharged inline-four cylinder engine. This engine is a member of GM’s Small Engine Family, known for its combination of direct injection, variable valve timing (VVT), and a twin-scroll turbocharger. Direct injection allows for precise fuel delivery, enhancing both power and efficiency. The twin-scroll turbocharger minimizes turbo lag, providing a more responsive driving experience. The engine produces 252 horsepower at 5500 rpm and 353 Nm (260.36 lb-ft) of torque between 2500 and 4500 rpm. This power is channeled through a sophisticated 9-speed automatic transmission, designed to optimize fuel economy and provide smooth gear changes. The Start/Stop system further contributes to fuel savings by automatically shutting off the engine when the vehicle is stationary.
Driving Characteristics
The 2.0-liter turbo engine paired with the 9-speed automatic delivers a noticeable improvement in performance compared to the base 1.5L engine. Acceleration is brisk, making highway merging and overtaking maneuvers relatively effortless. The 9-speed transmission, while generally smooth, can sometimes exhibit slight hesitation during downshifts. The all-wheel-drive system provides enhanced traction in various weather conditions, making it a suitable choice for regions with inclement weather. Compared to a hypothetical manual transmission version (which was not offered), the automatic prioritizes convenience and ease of use over outright driver engagement. The gear ratios are tuned for a balance between fuel efficiency and responsiveness, leaning towards the former.
Equipment & Trim Levels
The 2.0L AWD Terrain II typically came standard with features like an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, keyless entry, and a suite of safety features including automatic emergency braking and lane departure warning. Higher trim levels, such as the SLT and Denali, added premium features like leather upholstery, heated front seats, a power liftgate, and a Bose premium audio system. Optional extras included a panoramic sunroof, adaptive cruise control, and blind-spot monitoring. Interior upholstery generally consisted of cloth on lower trims, with leather becoming standard on higher-end models. Dashboard configurations were relatively consistent across trims, with variations primarily in trim materials and accent colors.
Chassis & Braking
The Terrain II utilizes an independent McPherson strut suspension in the front and an independent multi-link suspension in the rear. This setup provides a comfortable ride quality, absorbing bumps and irregularities in the road surface effectively. The all-wheel-drive system adds to the vehicle’s stability and handling. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The inclusion of ABS (Anti-lock Braking System) ensures safe and controlled stopping power. Steering is rack-and-pinion with electric power assist, providing a responsive and precise steering feel.
Market Reception & Comparison
Critics generally praised the Terrain II 2.0L AWD for its refined engine and comfortable ride. However, some reviewers noted the 9-speed transmission could be occasionally indecisive. Fuel economy was considered competitive for its class, averaging around 21 mpg city and 28 mpg highway. Compared to the 1.5L turbo version, the 2.0L offered a significant performance boost, but at a slightly higher price point and with a minor decrease in fuel efficiency. The 2.0L was often seen as a more compelling option for drivers who prioritized power and responsiveness over maximizing fuel savings. Compared to rivals like the CR-V and RAV4, the Terrain II offered a more stylish design and a more luxurious interior, but it sometimes lagged behind in terms of overall reliability ratings.
Legacy
The LTG 2.0-liter turbo engine has proven to be a relatively reliable powertrain, although some owners have reported issues with the timing chain and oil consumption. The 9-speed automatic transmission has also been subject to some criticism regarding its long-term durability. On the used car market, the Terrain II 2.0L AWD holds its value reasonably well, particularly models in good condition with low mileage. Its combination of performance, features, and all-wheel-drive capability makes it a popular choice among buyers seeking a versatile and capable compact SUV. While not without its flaws, the Terrain II 2.0L AWD represents a solid offering in the competitive compact SUV segment.
