Why it stands out
The 2021 GMC Yukon XL distinguishes itself in the full-size SUV segment with its blend of luxury, spaciousness, and powerful performance. With an extensive wheelbase that enhances passenger space, the Yukon XL is designed to accommodate large families comfortably. Noteworthy is the range of powertrains offered, including a fuel-efficient 3.0L Duramax turbo-diesel engine which is particularly appealing for those conscious of fuel economy without sacrificing capability. Its modern independent rear suspension allows for improved handling and ride comfort compared to previous models, making it agile despite its size. Inside, the Yukon XL combines advanced technology, including a user-friendly infotainment system, with premium materials, especially in the high-end Denali trim. However, potential buyers should keep in mind some users have pointed out concerns regarding brake performance and the gasoline engine's capabilities compared to the preferred diesel option.

Getting the diesel was the best decision! Far superior to the gasoline engine options.

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.
