EPA-estimated fuel economy for 2WD models is 21 mpg in the city and 22 on the highway; 4WD models are estimated at 20 mpg in both city and highway driving. That mileage, combined with the Silverado Hybrid’s 26-gallon (98 L) fuel tank, delivers a cruising range of more than 500 miles with 2WD models and more than 470 miles with 4WD models.
