KBB.com Review
Kbb.com Expert Rating
Professional yet premium attitude. Engines range from a turbo 4-cylinder to a 6-cylinder diesel and a big V8. Exclusive hardware and technology to enhance work or play. Denali — the popular Sierra luxury version.
Doesn’t tow quite as much as the Ford F-150 and Ram 1500. Also lacks those rivals’ max payload rating. Not on the cutting edge of tech.
