GM joined the half-ton diesel pickup truck competition with its Chevrolet Silverado 1500 and GMC Sierra 1500 siblings each getting the same turbo-diesel 3.0-liter inline-six-cylinder engine and 10-speed automatic transmission. EPA fuel economy ratings differ slightly between the two thanks to what we’ve been told is the more aerodynamic styling of the Silverado. After a short drive in the Silverado 1500 diesel earlier this year turned up impressive fuel economy figures, we were able to see if the Sierra 1500 would produce similarly solid numbers in a longer, more rigorous test.

Over a 200-plus-mile drive in southeast Michigan, the Sierra did remarkably well. Our 204.6 miles of driving used 6.4 gallons of diesel fuel, meaning the truck averaged an impressive 32.0 mpg — beating its EPA combined mpg estimate and even its highway mpg estimate. Cars.com reviewer Aaron Bragman called this “a fantastic result, turning the Sierra into a viable commuter vehicle when its prodigious torque is not being used to tow a camper trailer or a boat.”

Elsewhere in pickup news, we also took some time to examine how the Tesla Cybertruck stacks up against a crew-cab, 6.5-foot-bed Ford F-150, since that’s what Tesla used as its benchmark for a lot of the truck aspects of the Cybertruck (the automaker used a Porsche 911 as the on-road performance benchmark).
