2014 Chevrolet Silverado and GMC Sierra 6.2L V-8 Rated by EPA

A few weeks ago we learned the power and towing capabilities of General Motors’ redesigned Chevrolet Silverado and GMC Sierra trucks equipped with the 6.2-liter V-8 engine, and now we know the official EPA ratings for the engine, which is available in 2014 Chevrolet Silverado LTZ and High Country models as well as GMC Sierra SLT and Denali models. With rear-wheel-drive, the 6.2-liter V-8 achieves 15/21 mpg, and four-wheel-drive models are rated at 14/20 mpg city/highway.

Although the Chevrolet Silverado and GMC Sierra 6.2-liter models top the light-duty pickup class in terms of power with the V-8’s 420 hp and 460 lb-ft of torque, these fuel economy ratings trail those of the 2014 Ram 1500. When equipped with the 395 hp, 5.7-liter Hemi V-8 and an eight-speed automatic transmission, the 2014 Ram 1500 is rated at 15/22 mpg with rear-wheel-drive and 15/21 mpg city/highway with four-wheel-drive. The 2014 Ford F-150’s top engine is also a 6.2-liter V-8, but it lags behind both the Ram and the GM trucks with its 13/18 mpg rating for rear-wheel-drive models and 12/16 mpg city/highway rating for four-wheel-drive models.

The 6.2-liter V-8 is a $1995 option on Chevrolet Silverado LTZ and High Country trims and GMC Sierra SLT and Denali models and pairs exclusively with a six-speed automatic. This powertrain will go on sale later this fall.

The only thing preventing me from considering this vehicle right now is GM's failure to put the 8 speed auto in this vehicle.  As Ram has shown (according to this article) an 8 speed enhances mpg.  If they get it in the 2015, it will help compete with Ram and Ford, whose Atlas concept of weight reduction should help Ford enhance mpg in the F150.
