The 2014 GMC Sierra 3500HD, part of GMC's third generation of HD truck designs, is a reliable full-size pickup offered in both 2WD and 4WD configurations. It comes in three trims: Work Truck (WT), SLE, and SLT, and a multitude of bed and cab configurations. Its engine lineup consists of a 6.0L V8 gasoline engine that produces 360 hp, and a potent 6.6L V8 turbodiesel that pumps out an impressive 397 hp and 765 lb-ft of torque. Both engines are coupled with a heavy-duty, six-speed automatic transmission for smooth power delivery. Key safety features include antilock disc brakes, stability control, and front side and side curtain airbags. It lacks many modern infotainment features, but a basic AM/FM stereo with an auxiliary audio jack is standard.
