We recently put a 6.6 liter, V-8 Duramax-equipped Silverado to an exhaustive road test. Chevrolet does not publish official mileage figures for the Duramax diesels, which are produced by a joint venture between GM and Isuzu. The 25 come standard with the Vortec 6.0 liter V8, with the Duramax Diesel 6.6 liter turbo V8 available as an option.

Vortec MAX 6.0 liter V8 (Active Fuel Mangement)Īlthough Chevy offers diesel engine options for the Silverado, the diesels are only available in the 25 range trucks.

Vortec 5.3 liter V8 (aluminum-block, Active Fuel Management, with or without FlexFuel).

Vortec 5.3 liter V8 (iron-block, Active Fuel Management, with or without FlexFuel).

The 2WD 6.0-liter Silverado Hybrid is rated at 21 city/22 highway, while the 4WD Silverado Hybrid is rated at 20 city/20 highway. The most fuel efficient conventional choice is the 2WD 2010 Silverado XFE that delivers 15 city/22 highway miles per gallon. Silverado Engine OptionsĬhevrolet currently offers a slew of engine options in the half-ton Silverado 1500 range. While a nice jump in the Silverado’s gas mileage is coming, we’ll have to wait a bit. A 25- or 30-percent rise in the Silverado’s MPG average would have significantly positive implications. Due to the massive numbers sold, the Silverado’s gas mileage figures have a considerable impact on the nation’s rate of gasoline consumption. With over 630,000 sold in 2006, Silverado sales were only exceeded by Ford’s ever-popular F-series pickup trucks. Chevrolet’s Silverado is not only the second-best selling truck in America, it’s the second-best selling vehicle, overall.
