Every 2027 GMC Terrain is powered by a 1.5-liter turbocharged 4-cylinder engine producing 175 horsepower and 203 lb-ft of torque, paired with an 8-speed automatic transmission across the entire lineup. This marks a notable change from previous model years, since the base Elevation trim previously used a continuously variable transmission; for 2027, every Terrain shares the same gearbox regardless of trim. Front-wheel drive comes standard on Elevation, with all-wheel drive available for an additional cost, while AT4 and Denali both come standard with all-wheel drive for added traction in poor weather or light off-road conditions.

• 1.5L turbocharged 4-cylinder engine: 175 horsepower and 203 lb-ft of torque
• 8-speed automatic transmission standard across every trim
• EPA-estimated 26 mpg city / 28 mpg highway / 27 mpg combined on FWD models

The larger portrait orientation gives the Terrain one of the biggest standard displays in the compact SUV segment, and natural speech recognition means many functions can be controlled without ever touching the screen. The AT4 trim adds an available Technology Package II with a surround-view camera and recorder, a rear camera mirror, and traffic sign recognition, giving off-road-focused buyers extra visibility both on and off the pavement.
