Chevy Silverado hybrid gets official with the EPA 21mpg city/22mpg hwy

The EPA has posted the official mileage numbers for the new Two-Mode hybrid variants of the Chevy Silverado and GMC Sierra full-size pickup trucks. The open bed crew-cab hybrid trucks scored the same numbers as their full bodye SUV siblings. The rear wheel drive models came in at 21/22 mpg city/hwy while the four drive models achieved 20/20 mpg. The conventional model with the same 6.0L V8 only manages 14 mpg in town and 19 on the highway in rear wheel drive form. The hardware on the pickups is the same as the existing 2008 hybrid SUVs although the powertrain engineers kept plugging away at the control software after releasing the SUVs. The updated software will also be incorporated into the upcoming Saturn Vue Two-mode and the 2009 Tahoe/Yukon.
