2018 GMC Sierra 3500HD ratings and reviews

Four trim options and a choice between 2WD and 4WD in single or dual-wheeled configurations let drivers custom-build the GMC’s 2018 Sierra 3500HD to fit the needs of their loads. A robust Vortec 6.0L V8 SFI engine with variable valve timing, FlexFuel E85-capability and 360-horsepower powers each trim, while the Duramax 6.6L Turbo-Diesel V8 engine is available for those that prefer diesel. Suspension and trailing packages are included with all trims, while a Driver Alert Package with forward collision and lane departure alerts are available on the SLT and standard on the Denali. Denali trim also gives drivers some interior perks like wireless charging and a heated steering wheel. A 36-gallon tank offers drivers plenty of range on the highway even when towing heavy cargo. Each trim comes with a 3-year / 36,000-mile warranty and 5-year / 60,000-mile roadside assistance with two included scheduled maintenance visits for two years.
