General Motors trucks equipped with the company’s new 6.2-liter EcoTec3 V8 are officially rated to return up to 21 mpg on the highway.
Two-wheel drive Chevrolet Silverado and GMC Sierra trucks equipped with the larger engine are officially estimated to offer 15 mpg in city driving and 21 on the highway according to the U.S. Environmental Protection Agency. Models equipped with four-wheel drive suffer a single mile per gallon for 14 in the city and 20 on the highway.
That’s only one highway mpg below the 5.7-liter Hemi used in Ram pickup trucks, and the same in-city fuel economy. For such a small gap in consumption, GM’s new V8 is also considerably more powerful. It offers an extra 25 hp and 53 lb-ft of torque.

GM is limiting the trucks it offers with the more powerful V8, which offers 420 hp and 460 lb-ft of torque. Chevrolet’s new luxury-trimmed Silverado High Country along with the GMC Sierra SLT and Denali models are the only pickups on that list.
There are two other engine options for both Chevrolet and GMC’s line of new trucks. A 4.3-liter base V6 offers 285 hp and 305 lb-ft of torque while the bread-and-butter 5.3-liter V8 delivers 355 hp and 383 lb-ft. With the V6, drivers are able to tow up to 7,600 lbs, or 11,500 with the base eight-cylinder. Bumping up to the 6.2-liter raises that rating to 12,000 lbs.
