2014 Chevrolet Silverado: Active Fuel Management

December 06, 2013

2014 Chevrolet Silverado

Curious how "active" the 2014 Chevrolet Silverado's Active Fuel Management system is?

You can scroll through the instrument panel for a readout that shows when the 355-horsepower 5.3-liter direct-injected engine switches back and forth between four cylinders and eight.

In the lower right corner of the central IP display it'll either say "V4" or "V8."

Obviously anytime you're into the throttle for acceleration, it's in V8 mode. But much of the time during steady-state highway cruising, even at elevated speeds, it deactivates cylinders to save fuel.

Of note, our average fuel economy for the life of this test with the 2014 Silverado is 17.3 mpg, versus the EPA rating of 19 mpg combined (16 city/23 highway).
