We'll cover everything from its performance and features to its interior comforts and off-road capabilities. So buckle up and let's get started!

Performance and Powertrain

The 2018 GMC Sierra SLT All Terrain is built to perform, and it starts with its robust powertrain options. The standard engine is a 5.3-liter EcoTec3 V8, delivering a healthy 355 horsepower and 383 lb-ft of torque. This engine provides ample power for daily driving, towing, and light off-roading. For those who need even more muscle, there's an available 6.2-liter EcoTec3 V8, which cranks out an impressive 420 horsepower and 460 lb-ft of torque. This upgrade transforms the Sierra into a towing beast, capable of handling heavy loads with ease.

Both engines are paired with a smooth-shifting eight-speed automatic transmission. This transmission optimizes power delivery and fuel efficiency, ensuring a comfortable and responsive driving experience. The All Terrain package also includes a specially tuned suspension, providing enhanced off-road capabilities without sacrificing on-road comfort. The four-wheel-drive system is another critical component, offering selectable modes for various driving conditions, from everyday commuting to tackling challenging terrains. With its combination of powerful engines, advanced transmission, and capable four-wheel-drive system, the 2018 GMC Sierra SLT All Terrain is ready for anything you throw at it.

Fuel economy is always a consideration, and the 2018 Sierra SLT All Terrain does reasonably well for a full-size pickup. The 5.3-liter V8 offers an EPA-estimated 16 mpg city and 22 mpg highway, while the 6.2-liter V8 gets slightly lower figures. However, the performance gains of the larger engine may be worth the trade-off for those who need the extra power. In real-world driving, these numbers can vary depending on driving style and conditions, but overall, the Sierra offers competitive fuel economy for its class.
