2014 Chevrolet Silverado: Road Trip Fuel Economy
February 10, 2014
Recently, I drove our long-term 2014 Chevrolet Silverado from Los Angeles to Phoenix and back. The route itself is quite uninteresting. It comprises one straight, elevation-changeless highway, Interstate 10, for nearly all of the 825 miles.
Traffic was light, so I was able to make good time and keep the cruise locked for the majority of the miles, cruising at the speed of traffic for nearly the entire trip. Despite this the Silverado was still switching into fuel-saving four-cylinder mode with some regularity. Nice.
When all was said and done the big truck had netted 19.6 mpg. While this is (predictably) lower than its EPA highway rating, it's actually a touch higher than its combined EPA rating of 19 mpg. I consider this result a success, considering the truck is facing an uphill aerodynamic battle at these real-world freeway velocities. Remember, drag increases with the square of velocity.
