GM on Friday also released EPA fuel economy estimates for pickups with the automaker's 5.3- and 6.2-liter V-8 engines with a new Dynamic Fuel Management system that continually adjusts the number of cylinders firing -- down to two -- in various combinations based on performance needs.
The technology, however, will deliver modest fuel economy gains in line with comparable Ford F-150 and Ram 1500 models, according to EPA estimates.
Silverado models with the 5.3-liter V-8 with an eight-speed automatic and rear-wheel drive will achieve an EPA-estimated 17 mpg city/23 highway/19 combined -- 1 mpg better than the engine it replaces.
Models with four-wheel drive and the 6.2-liter V-8 and 10-speed automatic transmission will offer an EPA-estimated 16 mpg city/20 highway/17 combined -- the same combined as a comparably equipped 2018 Silverado.
