GMC Sierra 1500 full-size pickup

The 2014 GMC Sierra 1500 full-size pickup engine portfolio includes a 4.3L V6, a 5.3L V8 and a 6.2L V8. Each engine features standard direct injection, continuously variable valve timing and Active Fuel Management, which means they seamlessly switch to run on four cylinders during light-load driving to save fuel. On Extended Cab models, the Sierra has front-hinged rear doors with outside pull handles at the rear, providing improved access in tight parking spaces and allowing rear passengers to enter and exit the vehicle with the front doors remaining closed.
