(June 19, 2013) DETROIT — General Motors says the all-new 4.3-liter EcoTec3 V-6 powering the 2014 Chevrolet Silverado and GMC Sierra will be the most capable standard V-6 in any full-size pickup truck — leading the segment in city fuel economy and helping customers save money through a host of fuel-saving technologies.

EcoTec3 engine technology matches Ram HFE’s 18 mpg city, while 4x4 Silverado and Sierra models achieve 17 mpg city, the best of any full-size pickup. EPA highway estimates are highly competitive: 22 mpg for 4x4 versions, and 24 mpg for 2WD models.

The 4.3L V-6 also help Silverado and Sierra with the highest-available payload rating of 2,108 pounds and the highest available towing rating of 7,200 pounds.
