Why it stands out
The 2021 GMC Yukon XL distinguishes itself in the full-size SUV market with its impressive blend of space, power, and advanced features. As the long-wheelbase version of the standard Yukon, it offers significantly more room, especially for third-row passengers and cargo. Notably, the introduction of an independent rear suspension improves ride quality and handling, setting it apart from competitors. Buyers can choose from three powertrains, including the robust 6.2L V8 and the fuel-efficient 3.0L Duramax diesel, catering to a range of performance preferences. The latest infotainment system, spacious seating options, and advanced safety features enhance its appeal. While it may not excel in fuel economy compared to smaller crossovers, the Yukon XL offers unmatched capacity and comfort for families and adventurers alike.

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.
