What Expert Reviewers Say About the 2026 GMC Sierra 1500
MotorTrend scores the 2026 GMC Sierra 1500 8.8/10 and ranks it third among full-size trucks, and Car and Driver rates it 8.5/10, fifth among full-size pickups. Both praise the powertrain choices: MotorTrend says there is no bad engine option and calls Super Cruise excellent, and Car and Driver likes the towing and payload ratings and the Crew Cab's room. The trade-offs they note: MotorTrend finds the lower-trim interiors dreary and says the available 22-inch wheels hurt the ride, and Car and Driver says the lower trims push the limits of GMC's upscale image. MotorTrend also calls the Sierra 1500 functionally identical to the Chevrolet Silverado 1500, with nicer trim and materials.
“There’s no bad engine option, the truck drives nicely, and the Super Cruise hands-free driving system is excellent.”Read the full MotorTrend review
“The GMC Sierra is just as tough as its Chevy cousin but brings a bit more class and refinement to the workweek.”Read the full Car and Driver review
