Why it stands out
The 2021 GMC Yukon XL is a standout in the full-size SUV segment due to its impressive blend of space, versatility, and advanced features. As an enlarged variant of the Yukon, the XL provides an abundance of passenger room in the third row and vast cargo capacity, making it an excellent choice for families or those needing to transport groups. It introduces a modern independent rear suspension for enhanced ride quality, which, along with its three available powertrains—including an efficient 3.0L turbo-diesel option—caters to a diverse range of consumer preferences. The introduction of the AT4 trim level ensures off-road enthusiasts have a capable vehicle, while the luxurious Denali trims deliver a premium experience with high-end materials and cutting-edge technology. However, potential buyers should be mindful of fuel economy, which could be less than ideal compared to smaller SUVs or crossovers.

The vehicle provides passenger comfort for lengthy travel. The driver is provided information within his view for safe driving and locating turns. There is abundant storage room and the third row allows a large group to travel together

I am really surprised with this vehicle. It’s massive, but even as big as it is, it’s very agile and easy to drive. The engine has enough power to push this beast in and out of right situations. I do wish the brakes had a bit more to them but all in all fun to drive. Doesn’t feel like a us. The interior is well appointed and looks fantastic.

I believe it to be a great SUV. I would compare the luxury and on board features to Cadillac.
