Real-World Commuting in Indiana

Translating a 28 highway mpg rating means significantly fewer interruptions at the pump during long road trips across the Midwest. When paired with the smooth-shifting 10-speed automatic transmission, the Duramax engine actively keeps revolutions low at cruising speeds, reducing active fuel burn during extended trips on Interstate 70.

Meanwhile, the advanced Dynamic Fuel Management system available on the EcoTec3 V8 engines allows the truck to automatically deactivate specific cylinders when full power is unnecessary. This active management provides the raw horsepower of a V8 when pulling a heavy trailer, but seamlessly transitions to operating on fewer cylinders to conserve fuel when cruising through downtown Camby with an empty bed.
