The GMC Sierra 1500 has plenty of engines to choose from with lots of power. Both V8 engines pull hard off the line, but the 420-horsepower 6.2-liter V8 holds a special place in our hearts. Sure, it lacks the head-pinning performance of the F-150 Raptor, but it’s plenty for most drivers.
The standard eight-speed automatic transmission paired with the 5.3-liter engine and the 10-speed that comes with the 6.2-liter engine are silky smooth. But despite all the complexities of these higher-cog-count transmissions and active fuel management, the Sierra 1500 is still a fuel hog. Models with the base 5.3-liter V8 and rear-wheel drive achieve an EPA-estimated 17 miles per gallon city, 23 mpg highway, and 19 combined.
Finally, despite all its power and reduced weight in the new model year, the Sierra is upsetting in the hauling department. It can tow up to a 12,000-pound trailer and haul up to 2,240 pounds in its bed, which are 1,000 pounds and 300 pounds less than the F-150, respectively. What the Sierra offers is new technology to make towing easier, like the available Hich Guidance system and Trailer Camera Package.
