GMC Sierra Mixes Power With Efficiency

2013 GMC Sierra 1500 Truck in Saginaw

GMC engineers achieved a remarkable balance of power with fuel efficiency with the 2013 GMC Sierra 1500. It starts with Sierra XFE, a 2WD V-8-powered Crew Cab. Its standard 315-hp 5.3L V-8 offers an EPA -estimated 22 hwy mpg, the best of any competitive V-8 in its class. The 2013 GMC Sierra 1500 is also available with a 403-hp Vortec 6.2L V-8 that is the highest output V-8 GM has ever put in a GMC 1/2-ton pickup.

Vortec gasoline-powered V-6 and V-8 engines available in the 2013 GMC Sierra 1500 are remarkable for the technology they bring to the full-size pickup. The results: power of up to 403 hp from the available Vortec 6.2L V-8, and competition leading V-8 fuel efficiency of up to 22 mpg hwy from the available Vortec 5.3L V-8.

GMC Vortec V8 Engine To give you uncompromised power and torque for confident daily driving, passing and trailering, look no further than the Vortec engine family. Each model uses innovative “vortex technology” to swirl and tumble incoming air and fuel for optimum power and response.For easy responsiveness in low-speed city driving and bold power for open-road passing or trailering, many Vortec engines feature VVT. It monitors and changes valve open and close points for near-peak levels of torque across the entire range of engine speeds.

The 2013 GMC Sierra 5.3L V-8 engines use Active Fuel Management. This available system senses load and demand, then activates or deactivates four of the engine’s eight cylinders. In Sierra XFE, the result is competition leading V-8 EPA –estimated highway fuel economy of 22 mpg. A valve lifter (above) deactivates the cylinder. Under high-demand conditions, the valve’s switching mechanism is depressurized, reengaging the cylinder and restoring full power, without you ever noticing the transition.
