Introduction
The 2016-2017 GMC Terrain with the 3.6L V6 and automatic transmission was positioned as a step up from the base 2.4L four-cylinder model. It aimed to attract buyers who desired more robust acceleration and towing capacity without sacrificing the practicality and comfort expected of a compact SUV. The facelifted Terrain, built on the GM Theta platform, offered a more contemporary design and improved interior features compared to the original 2010 model. This variant was primarily sold in the North American market, where V6 engines remained popular for their perceived refinement and capability.
Powertrain & Engine Architecture
At the heart of this Terrain variant lies the GM LFX 3.6-liter V6 engine. This engine is a naturally aspirated, 60-degree V6 featuring direct fuel injection and variable valve timing (VVT). The direct injection system optimizes fuel delivery for improved efficiency and power output. The LFX engine is known for its relatively smooth operation and respectable power delivery. The six-speed automatic transmission (6T70) was the sole transmission option paired with the V6. This transmission is a conventional torque converter automatic, offering smooth shifts and a comfortable driving experience. It features electronically controlled shifting and adaptive learning to optimize shift points based on driving conditions. The transmission was designed to handle the engine’s 301 horsepower and 270 lb-ft of torque effectively.
Driving Characteristics
The 3.6L V6 significantly altered the driving experience compared to the four-cylinder Terrain. Acceleration was noticeably quicker, making merging onto highways and overtaking maneuvers easier. While not a sports SUV, the V6 provided ample power for everyday driving situations. The six-speed automatic transmission contributed to a relaxed highway cruising experience, with relatively low engine speeds at typical highway velocities. The gear ratios were tuned for a balance of acceleration and fuel economy. Compared to a manual transmission, the automatic offered convenience but sacrificed some driver engagement. The front-wheel-drive configuration provided adequate traction in most conditions, but all-wheel drive was available as an option for enhanced stability in inclement weather.
Equipment & Trim Levels
The 3.6L V6 engine was typically offered on the SLT and Denali trim levels of the Terrain. Standard features on these trims included leather upholstery, heated front seats, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a rearview camera. Optional extras included a power liftgate, a panoramic sunroof, and a premium Bose audio system. The Denali trim, being the top-of-the-line offering, added unique exterior styling cues, such as a distinctive grille and chrome accents, as well as additional interior refinements.
Chassis & Braking
The Terrain’s chassis featured an independent coil spring suspension at all four corners, providing a comfortable ride quality. The front suspension utilized MacPherson struts, while the rear suspension employed a multi-link design. Ventilated disc brakes were standard on all four wheels, providing adequate stopping power for the vehicle’s weight and performance. An anti-lock braking system (ABS) was also standard, enhancing safety during emergency braking situations. The Terrain’s steering system employed an electric power steering (EPS) system, offering light and precise steering feel.
Market Reception & Comparison
Critics generally praised the Terrain’s spacious interior and comfortable ride. The 3.6L V6 engine was well-received for its smooth power delivery and improved acceleration compared to the base engine. However, some reviewers noted that the Terrain’s handling was not as sporty as some of its competitors. Fuel economy was considered average for the segment. Compared to the four-cylinder Terrain, the V6 variant commanded a higher price but offered a more refined and capable driving experience. Competitors such as the Honda CR-V, Toyota RAV4, and Ford Escape offered similar features and performance, but the Terrain distinguished itself with its available V6 engine and distinctive styling.
Legacy
The LFX 3.6L V6 engine proved to be a reliable powertrain in the Terrain, with relatively few reported issues. The six-speed automatic transmission also demonstrated good durability. On the used car market, the 2016-2017 Terrain with the V6 engine holds its value reasonably well, appealing to buyers seeking a well-equipped and capable compact SUV. Regular maintenance, including oil changes and transmission fluid services, is crucial for ensuring the long-term reliability of this powertrain. While newer Terrain models have moved towards turbocharged four-cylinder engines, the V6 variant remains a popular choice for those who appreciate its smooth power delivery and proven track record.
