The fuel efficiency of a vehicle is measured in miles driven/gallons of fuel consumed. The EcoTec3 technology has improved engine and fuel efficiency in both the V-6 and V-8 engine options of the 2015 Chevy Silverado 2500HD. Active fuel management in the V8 engines deactivate cylinders when full power is not needed, while variable valve timing adjusts air flow in the combustion chamber to maximize fuel efficiency and minimize harmful emissions.
