The Chevrolet Suburban and GMC Yukon XL are mechanical twins: they share the same platform, dimensions, engines and independent rear suspension, and they’re built on the same assembly lines. The differences are styling, interior design, trim levels and brand positioning — GMC aims a little more upmarket, especially with its Denali and Denali Ultimate trims. For passengers, both offer the same generous space: three usable rows and one of the largest cargo areas of any SUV.

Space: identical

Because they share a body structure, third-row room and cargo space are essentially the same. Both became significantly roomier with the 2021 redesign. Read the 2021 Suburban redesign.

Interior and trims

The Yukon XL Denali and Denali Ultimate offer more upscale materials, unique wood and leather and features like Super Cruise and air suspension as standard on top trims. Chevrolet’s High Country trim is also luxurious. Read Yukon Denali Ultimate explained.

History

The Yukon XL was sold as the GMC Suburban until 2000. Read the Yukon XL history and the Suburban history.

Which should you book?

In chauffeured service, the difference is mostly cosmetic. We typically recommend the Suburban for up to six passengers and the Yukon XL for up to seven, depending on seating configuration and luggage. See our Chevrolet Suburban and GMC Yukon XL.
