The Sierra 5.3L V-8 engine EPA-estimated fuel economy improves for 2010 from 14 city / 20 highway to 15 city / 21 highway MPG, while Extra Fuel Economy (XFE) models move from 15 city / 21 highway to 15 city / 22 highway MPG. This development, combined with the fact that GM's hybrid pickups achieve an EPA estimated 21 city / 22 highway, puts the 2010 GMC Sierra at the top in fuel economy.
Some other changes made to the GMC Sierra that can be attributed for its fuel efficient success is the development of a new fuel saver mode which enables the truck to make better use of GM's Active Fuel Management system, running on four-cylinders in light throttle conditions instead of eight. More efficient six-speed transmission shift points, engine variable valve timing and a lower gear ratio of 3.08 (now standard on GM full-size pickups) each play an important role in the improved fuel economy.
These new improvements come with no compromise to prior GMC capabilities. Horsepower, payload, and trailering specifications remain the same for the GMC Sierra. The following is the most recent available EPA-estimated comparable fuel economy data for GM's main competitors in this segment:
Ford - 5.4L: 14 city / 20 hwy; 4.6L with 6-speed transmission:
Dodge - 5.7L: 14 city / 20 hwy
Toyota - 5.7L: 14 city / 18 hwy; 4.6L: 15 city / 20 hwy
Nissan - 5.6L: 13 city / 17 hwy; 5.6L (E85): 13 city / 18 hwy
