The 2017 GMC Terrain is powered by two gasoline engines: a 2.4-liter inline-four that’s standard, and an optional 2.0-liter turbocharged inline-four available on higher trims. Both engines mate with a six-speed automatic transmission, and all-wheel drive is available on most configurations.
In practice, the Terrain shares its engine lineup with the Chevrolet Equinox of the same era. The exact engine in a given vehicle depends on trim and market. The overview below outlines the two engines GM offered for the 2017 Terrain and what they mean for daily driving.
Engine options for the 2017 Terrain
The following list summarizes the two engines GM offered for the 2017 Terrain, including their basic characteristics and typical drivetrain configurations.
- 2.4-liter inline-4 (Ecotec) — a naturally aspirated gasoline engine commonly producing about 182 horsepower and around 172 lb-ft of torque; paired with a six-speed automatic transmission; available in front-wheel drive or all-wheel drive.
- 2.0-liter turbocharged inline-4 — a turbocharged gasoline engine that delivers noticeably more power and torque than the base engine (roughly in the low-to-mid 200s horsepower with strong low-end torque); typically paired with a six-speed automatic and available with all-wheel drive.
These two options illustrate GM’s approach for the Terrain: a efficient base engine and a more powerful turbocharged option for buyers seeking stronger acceleration and highway performance.
Performance and practicality considerations
Transmission, drivetrain, and tuning
All 2017 Terrain models use a six-speed automatic transmission. All-wheel drive is offered on most configurations, with front-drive being standard on the base setup. The turbo engine typically pairs with AWD in many trims for better traction and performance.
Fuel economy and real-world use
Expect the 2.4L engine to deliver better fuel economy in typical city and highway driving, while the 2.0L turbo adds acceleration capability at the expense of some efficiency. Actual mpg will depend on drivetrain, tires, and driving style.
Summary
In short, a 2017 GMC Terrain is powered by either a 2.4-liter inline-4 or a 2.0-liter turbocharged inline-4, both mated to a six-speed automatic and with optional all-wheel drive. If you’re evaluating a used 2017 Terrain, verify the exact engine by checking the VIN or the vehicle’s label, as trims and markets differ.
