What are the Engines in GMC Trucks?

GMC trucks, with their bold iconic profile and versatility, have always been a mainstay on the roadway. Available with four different kinds of engines, GMC trucks offer drivers unmatched control over how much power their vehicle has. When you’re shopping for a GMC Sierra truck, you’ll have your choice when it comes to which engine powers your car. But what are the engines in GMC trucks? Where do you start? To help make choosing an engine for your vehicle less intimidating, the team at Circle Buick GMC has put together this guide to help you select which engine is the best fit for your own GMC truck.

GMC Sierra 1500 engines

The GMC Sierra 1500 is one of the best-selling vehicles in the U.S. for a good reason—it’s stylish, fun to drive, and incredibly versatile. This light duty truck can really do it all, whether you’re in it for hauling power or just want a truck you’ll look forward to getting behind the wheel of every day. It also comes with four engine offerings, which we’ve broken down below.

• TurboMax™ 2.7-liter turbocharged I-4 The TurboMax™ 2.7L comes with an eight-speed automatic transmission and generates 310 horsepower and 430 lb-ft of torque. When it comes to half-ton gas-powered pickups, the TurboMax™ 2.7L offers best-in-class torque, has an available max towing capacity of up to 9,500 lbs, and gets a 19 combined city/highway mpg! What makes the TurboMax™ such a standout is that it’s modeled after diesel motors, with a fully forged bottom end that allows it to handle increased power without the risk of stress-based damage.
• 5.3-liter V8 The 5.3L V8 engine comes with a ten-speed automatic transmission and generates 355 horsepower and 383 lb-ft of torque, enabling it to tow up to 11,200 lbs. That increase in power means the 5.3L V8 gets a combined 18 city/highway mpg, which is an impressive showing for an engine of its caliber. The 5.3L V8 comes standard on the SLT and Denali trims, and is available on PRO, SLE, and Elevation trim levels.
• 6.2-liter V-8 The 6.2L V8 engine uses a ten-speed automatic transmission and gets 420 horsepower and 460 lb-ft of torque, increasing the GMC Sierra 1500’s towing capacity to 13,100 lbs and giving it a combined city/highway mpg of 18. This engine is the perfect choice for those looking to take on the most difficult jobs—or are after some seriously big fun. Featuring a Dynamic Fuel Management system, which alternates between different firing orders based on demand, which is continuously calculated and recalculated to ensure that your engine keeps running at peak performance. It comes standard on the Denali Ultimate trim.
• Duramax® 3.0-liter turbo-diesel I-6 The Duramax® 3.0L turbo-diesel I-6 engine features a ten-speed automatic transmission and puts 305 horsepower and 495 lb-ft of torque beneath the hood, bringing you best-in-class highway fuel economy of 23 mpg (and 21 city mpg).

The Duramax® also comes with Active Thermal Management to keep your engine running at an ideal temperature; in addition, the electrically controlled, variable-geometry turbocharger ensures responsive acceleration.
