2018 GMC Sierra 1500 Performance and Engine

EcoTec3 5.3L V8 — Built for the Central Valley

Under the hood of this Sierra 1500 SLT sits GMC's acclaimed EcoTec3 5.3L V8 engine, paired with a smooth-shifting 8-speed automatic transmission. This combination delivers an estimated 355 horsepower and 383 lb-ft of torque — more than enough muscle for towing trailers, hauling heavy loads through San Joaquin Valley terrain, or simply merging confidently onto Highway 99. The rear-wheel drive configuration keeps things straightforward and cost-effective to maintain, and the 8-speed automatic is tuned for efficiency, helping the truck make the most of every gallon of fuel on long highway stretches. GM's Dynamic Fuel Management technology, standard on the EcoTec3 5.3, allows the engine to run on fewer cylinders during light-load driving — a smart feature that stretches your fuel budget without sacrificing performance when you need it.

What the SLT Trim Brings to the Table

The SLT sits near the top of the Sierra 1500 lineup, and it shows.

The GMC IntelliLink infotainment system with an 8-inch color touchscreen keeps you connected with Apple CarPlay, Android Auto, and available built-in navigation. Driver-assist technology including lane keep assist, forward collision alert, and a rearview camera make everyday driving safer and less stressful. Dual-zone automatic climate control, a power-adjustable driver's seat, and a stylish chrome-accented interior give this Sierra a premium feel that owners consistently appreciate. The SLT also typically includes upgraded exterior trim details, chrome door handles, and 18-inch alloy wheels that complement the Quartz paint beautifully.

A Truck with a Reputation That Precedes It

The 2018 GMC Sierra 1500 earned strong reliability marks from both industry analysts and everyday owners.
