When the Two-Mode Silverado Hybrid hits the market next fall, it will likely boast best in class fuel economy while still managing to tow 6,100 lbs. While it's not that hard to beat the most miserly of full-size pickups in the MPG dept., doing that without sacrificing very much of the truck's capabilities is what's most impressive about the Silverado Hybrid. GM quotes fuel savings to be 40% better in city driving, with a 25% improvement overall. The hybrid Silverado can also hit 30 mph in electric-only mode for up to one mile depending on battery's state of charge.
