2015 Chevrolet Silverado vs. 2015 Ford F-150: Which Should You Buy? - U.S. News & World Report (blog)
While both trucks come with a base V6, Ford offers one V8 and two turbocharged (EcoBoost) V6 engines in the F-150, including one as its top engine. By comparison, Chevrolet's availability of a standard V6 or two V8 choices is a more traditional offering in a segment where a V8 engine has long been a default choice. Although Chevy's optional V8s have a bit more horsepower and torque than Ford's EcoBoost V6s, they also have lower EPA fuel economy ratings. Source: usnews.rankingsandreviews.com
