MPG estimates on this website are EPA estimates; your actual mileage may vary. For used vehicles, MPG estimates are EPA estimates for the vehicle when it was new. The EPA periodically modifies its MPG calculation methodology; all MPG estimates are based on the methodology in effect when the vehicles were new (please see the Fuel Economy portion of the EPAs website for details, including a MPG recalculation tool).
The features and options listed are for the new 2018 GMC Sierra 1500 and may not apply to this specific vehicle.
