Finally, the finer details on the 2014 Chevrolet Silverado and GMC Sierra 1500 pickup trucks have gone official. And one of the most important features was announced today, with the trucks being rated at an EPA estimated 16 MPG in the city and 23 highway when equipped with the new 5.3L EcoTec3 V8 and six-speed automatic transmission. With four-wheel-drive, fuel economy is only penalized by 1 mpg on the highway. In terms of combined mileage, the two-wheel-drive trucks see 19 combined miles per gallon, while the 4×4 models see 18.
When strictly speaking V8s, that’s 2 MPG higher than a comparative 2013 Ford and 3 MPG higher than Ram. But in fact, fuel economy estimates even beat those of the 2013 Ford F-150 equipped with the popular EcoBoost V6 engine in highway and combined fuel economy.
The 5.3L engine also balances efficiency with a decent amount of power. The mid-range powerplant delivers an SAE certified 355 hp and 383 lb.-ft. of torque –- an increase of 40 hp and 48 lb-ft compared to the outgoing 2013 model. Details about the more powerful 6.2L engine haven’t been released yet, so stay tuned.
