Why is there no active fuel management?
By Jock Russell on
Vehicle2010 GMC Sierra 1500 Denali 4dr Crew Cab 5.8 ft. SB (6.2L 8cyl 6A)
ReviewYukons have active fuel management 22 mpg why not the truck truck only gets 17 mpg if lucky this was a poor design
Best FeaturesStyling and interior are great
Worst FeaturesThis gas guzzler needs the active fuel management like they have on the other models like Yukons/Denali
