Fresh off a complete redesign, the 2020 GMC Sierra is a highly capable full-size truck. Now available with a diesel engine, the Sierra has similar underpinnings and powertrain choices as its Chevrolet Silverado sibling, but it distinguishes itself with a bit more premium flair and design differences. It trails the Ford F-150 in some specs, but boasts an exclusive multifunction tailgate and innovative towing aids.
