Range Technology

Range optimizes your GM vehicle's fuel economy by better identifying your driving situations helping you get more miles out of a gallon of gas. Active Fuel Management, available on most GM trucks and SUVs, helps lower fuel costs by enabling V8 engines to behave like four-cylinder engines when cruising with light loads, while seamlessly unleashing their full muscle whenever needed. However, studies have shown that factory installed AFM drops to 4 cylinders 35% of the time even though the average driver only requires full performance about 10% of the time. As such, Range allows you to drive in V4 mode 90% of the time - saving an average driver 65 gallons per year, or about $250.
