2014 GMC Sierra 2500HD

The all-new 2014 Sierra 1500 full-size pickup is the most powerful, most advanced and most refined truck in GMC's 110-year history.

Sierra's bold new exterior houses one of three all-new EcoTec3 engines, a fully updated cabin with available next-generation IntelliLink connectivity and other features designed for the most discerning truck owners.

The 2014 Sierra boasts the longest list of standard features ever for a full-size GMC pickup. From connectivity solutions, to a standard tie-down system in the rear, to the segment's only standard projector beam headlamps, many premium features are found on each and every all-new Sierra.

Sierra's engine portfolio is updated for 2014 with the goal of increased in power, torque and fuel efficiency across the board. There is a 4.3L V-6, a 5.3L V-8 and a 6.2L V-8 offered, all from a shared EcoTec3 engine family. 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.

For the first time on Extended Cab models, the 2014 Sierra has new front-hinged rear doors with outside pull handles at the rear, providing improved access in tight parking spaces. Unlike trucks with rear-hinged doors, Sierra's layout allows rear passengers to enter and exit the vehicle with the front doors remaining closed.

Crew Cab customers, who represent more than 60 percent of retail Sierra customers, can choose between two bed lengths; in addition to the current 5-foot, 8-inch box, a new 6-foot, 6-inch box is available. Regular cabs continue to be available with the 6-foot, 6-inch or 8-foot box lengths, while the extended cab will come exclusively with a 6-foot, 6-inch box.
