Our 5.3L EcoTec3 V-8 offers the proven power and dependability of our V-8 truck engines, with better highway fuel economy than a leading competitor's smaller turbocharged V-61. It combines tested technologies like Active Fuel Management, Direct Injection and continuously Variable Valve Timing to provide class-leading fuel efficiency3 with the peace of mind that comes with our reliable engine designs. No matter which EcoTec3 engine you choose, Silverado offers you a fuel-efficient and powerful option7.
Direct Injection monitors a number of variables to determine the precise measure of highly pressurized fuel to inject into each cylinder. The result is combustion that optimizes engine power and fuel efficiency7 while reducing emissions.
DFI optimizes engine power and fuel efficiency3 while reducing emmissions.
In low-demand situations when full engine power is not needed, Active Fuel Management deactivates cylinders, effectively turning a V-6 or V-8 EcoTec3 engine into a fuel-sipping four cylinder7. When it senses the need for full power, AFM instantly re-engages all cylinders.

Variable Valve Timing ensures Silverado performs at optimum power and efficiency. It continuously varies valve timing to keep our EcoTec3 engines operating near peak output across a wide rpm range, while minimizing emissions.

Integrated pocket hand grips make it easier
to enter the box while stepping on the new
CornerStep rear bumper. The available EZ-
Lift and Lower Tailgate opens without a thud
and can be closed with one hand. Available
LED lamps under the bed rails make it
easier to see items in the bed, even with a
tonneau cover on. Standard bed rail
protectors help avoid damage, load after load.
