Just as General Motors made a big deal about the 2014 Chevrolet Silverado and GMC Sierra 1500 getting better fuel economy than Ford's EcoBoost V-6 with the new 5.3-liter EcoTec3 direct-injected V-8, the company is also claiming victory in V-6 fuel economy as well, although the margin is not quite as decisive this time around. The 2014 EPA figures for the Silverado and Sierra 1500 equipped with the 4.3-liter V-6 are 18 city, 24 highway mpg for two-wheel-drive models, and 17 city, 22 highway for four-wheel-drive models.

This compares with 17 city, 23 highway for the Ford F-150 equipped with the base 3.7-liter V-6, and 17 city, 25 highway for the Ram 1500 with the 3.6-liter Pentastar V-6 . The Ford gets 16 city, 21 highway with the 3.7-liter V-6 and four-wheel drive, and the Ram 1500 gets 16 mpg city and 23 mpg highway in 4x4 trim.

Ram matches the new GM models for city fuel economy, but only in special fuel-sipping HFE trim. GM also points out the 4.3-liter V-6 produces more peak torque at a lower rpm than either Ford or Ram, and that the Silverado and Sierra V-6's maximum towing of 7200 pounds and payload of 2108 pounds are higher than competitors' models equipped with the base engine.
