You get four robust powertrains. The turbocharged 2.7L four-cylinder makes 310 horsepower and a class-leading 430 lb-ft of torque. Two V8s: the 5.3L with 355 hp and the 6.2L pumping 420 hp. For efficiency, the 3.0L Duramax turbodiesel delivers 305 hp and 495 lb-ft of torque while achieving up to 28 MPG on the highway.
Max towing hits 13,300 lbs when properly equipped. That's enough for large boats, construction gear, or a full camper. The 10-speed automatic transmission is standard across most trims, providing smooth shifts under load.
