For comparison's sake, most modern trucks manage between 5.5 and 6.5 mpg. For most long-haul truck drivers, an increase in fuel economy of 54 percent would equate to a savings of around $25,000 per year at current diesel prices.
Fuel Economy: 20 mpg city/23 mpg highway. We recommend the gas/electric Silverado Hybrid for fuel-conscious folks who plan to do a lot of driving in the city, because that's where it shines. Twenty mpg in urban driving is quite simply unheard of for a full-size truck, especially one with 332 hp (379 hp with electric assist) and 367 lb-ft of torque. On the downside, the complicated transmission is sometimes slow to respond, and the price is high.
