Green cars seemed to be the theme of the 2008 LA Auto Show and GMC was ready. The 2009 GMC Sierra Hybrid was present and showed everyone that even truck can be green.
The Sierra Hybrid has and epa of 21 city/22 hwy compared to the Sierra 1500 non-hybrid with 6.0L engine which has an epa of 14 city/19 hwy. Helping the hybrid reach these miles is a Vortec V8 6.0L engine producing 332hp and 367lb-ft of torque at 4,100rpm. Any thoughts?
