Pickup truck - 2013 Chevrolet Silverado Hybrid
Gas mileage (city/highway; combined mpg): 20/23; 21
Efficiency-cost rating: 0.50
As the more affordable version versus its sibling, the GMC Sierra Hybrid, the 2013 Chevrolet Silverado takes the top spot with a modest efficiency-cost rating of 0.50. If you insist on a Chevy pickup — or want a hybrid for hybrid’s sake — the Silverado Hybrid is for you. But you can do better: The high-efficiency version of the 2013 Ram 1500, called the HFE, has a 0.71 efficiency-cost rating. It’s not the cheapest 1500 truck, at $29,505, and its towing capacity tops out at 4,750 pounds, but it’s much cheaper than the Silverado Hybrid and has the same combined mileage estimate of 21 mpg. The Silverado Hybrid tows up to 6,100 pounds, though.
