The 2010 GMC Sierra 1500
offers something for everyone as a full-size truck utility and a dose of luxury. With three cabs, three cargo beds, six engines, five suspension and four interior packages, the Sierra 1500 can be custom built to each buyer's specifications. The vehicle was last redesigned in 2007, and changes for 2010 are minimal. All Sierra engines are now flex fuel capable, which means they can run on gasoline or E85 ethanol.
