The GMC Canyon II Crew Cab Long Box, equipped with the 3.6-liter V6 engine producing 308 horsepower and paired with an 8-speed automatic transmission, represents a notable advancement in GMC’s mid-size pickup truck lineup. Produced for the 2015 and 2016 model years, this configuration struck a balance between capability, comfort, and modern features. It was part of the second generation of the Canyon (designated Canyon II), a re-engineered and refined version of the Chevrolet Colorado, sharing its platform and many components. This generation marked GMC’s return to the mid-size truck segment after a period of absence, aiming to provide a more premium alternative to competitors like the Toyota Tacoma and Nissan Frontier.

Powertrain & Engine Architecture
The 3.6-liter LFX V6 engine powers this Canyon variant. This engine is a naturally aspirated, 24-valve DOHC (Double Overhead Camshaft) engine featuring direct fuel injection and variable valve timing (CVVT). The direct injection system optimizes combustion efficiency and power delivery, while CVVT enhances both low-end torque and high-end horsepower. The engine’s aluminum block and cylinder heads contribute to weight reduction. The 8-speed Hydra-Matic automatic transmission was a significant upgrade for the Canyon II, offering smoother shifts and improved fuel economy compared to older automatic transmissions. The transmission’s gear ratios were tuned to balance acceleration with highway cruising efficiency. The longitudinal engine layout, coupled with rear-wheel drive, provided a traditional truck feel and optimized weight distribution.
Driving Characteristics
The 308-horsepower V6 and 8-speed automatic combination delivered a noticeable performance increase compared to the base 2.5-liter four-cylinder engine option. While not as powerful as the available Duramax diesel engine, the V6 provided ample power for everyday driving and towing. Acceleration was brisk, and the transmission generally shifted smoothly and responsively. The 8-speed transmission helped keep the engine in its optimal power band, providing good passing power. However, some reviewers noted that the transmission could occasionally hunt for gears, particularly during uphill climbs. The rear-wheel drive configuration offered a more engaging driving experience than some competitors, but also meant that traction could be limited in slippery conditions.
Equipment & Trim Levels
The 3.6L V6 automatic was available on several Canyon trim levels, including the SLE and SLT. The SLE trim typically included features like a rearview camera, an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a USB port. The SLT trim added features such as leather upholstery, heated front seats, a power-adjustable driver’s seat, and a premium audio system. Optional extras included a navigation system, a Bose audio system, and a trailering package. Interior materials were generally considered to be of good quality for the segment, offering a more refined feel than some other mid-size trucks.
Chassis & Braking
The Canyon II utilized a body-on-frame construction, providing a robust and durable platform. The front suspension featured independent coil springs, while the rear suspension employed a traditional leaf spring setup. This configuration balanced ride comfort with load-carrying capacity. Braking duties were handled by disc brakes on all four wheels, with ABS (Anti-lock Braking System) standard. The front brakes measured 310x27mm, while the rear brakes were 324x18mm. The braking system provided adequate stopping power for most driving situations, although some reviewers noted that the brake pedal felt somewhat soft.
Market Reception & Comparison
The 2015-2016 GMC Canyon II with the 3.6L V6 and automatic transmission was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and capable powertrain. Compared to the base four-cylinder engine, the V6 offered a significant improvement in performance. Fuel economy was respectable, averaging around 18 mpg in the city and 25 mpg on the highway. However, the V6’s fuel economy was lower than that of the diesel engine. Compared to competitors like the Toyota Tacoma, the Canyon offered a more comfortable ride and a more modern interior, but the Tacoma was often praised for its off-road capability and long-term reliability.
Legacy
The LFX 3.6L V6 engine proved to be a relatively reliable powertrain when properly maintained. Common issues included oil leaks and occasional problems with the direct injection system. The 8-speed automatic transmission also generally proved durable, although some owners reported minor issues with shifting smoothness. On the used car market, the 2015-2016 Canyon II with the 3.6L V6 automatic remains a popular choice for buyers seeking a capable and comfortable mid-size pickup truck. Its blend of performance, features, and reliability makes it a compelling option in its price range. The Canyon II helped re-establish GMC as a player in the mid-size truck segment and paved the way for future iterations of the Canyon.
