The all-new 2014 GMC Sierra 1500 full-size pickup truck arrives at dealers later this spring with the best V-8 pickup fuel economy in the industry. Sierra’s new 5.3L EcoTec3 V8 uses direct injection, cylinder deactivation and variable valve timing to achieve EPA estimates of 16 mpg city and 23 highway with two-wheel drive or 16/22 with four-wheel drive.
In addition to highway estimates that are 2 mpg higher than a comparative 2013 Ford and 3 mpg higher than Ram, Sierra’s new V-8 fuel economy estimates also measure higher than those of the 2013 Ford F-150 EcoBoost V6.
The new 5.3L EcoTec3 V-8 combines its leading fuel efficiency with performance and capability. With an SAE certified 355 hp and 383 lb-ft of torque – increases of 40 hp and 48 lb-ft compared to the 2013 model – Sierra’s new 5.3L offers a class-leading towing capacity of up to 11,500 pounds.
The 5.3L EcoTec3 V-8 is just one of three more efficient new engines for the Sierra. With a standard 4.3L EcoTec3 V-6 that arrives this summer and a long list of standard features, the 2014 Sierra will have a manufacturer’s suggested retail price of $25,085.
Compared to the 2013 Sierra, the new model adds a standard 4.2-inch radio display, a locking tailgate, projector headlamps, a CornerStep rear bumper, cloth seats (versus vinyl in other trucks), DuraLife brake rotors and other all-new features. The truck’s all-new 4.3L EcoTec3 V-6 and six-speed automatic transmission is engineered to offer improved efficiency and capability, with additional details coming later.
Sierra also will be available later this year with an all-new 6.2L EcoTec3 V-8 with even more power, torque and capability than the 5.3L. Additional specifications for the 6.2L will be released later.Source: gmc
