Why it stands out
The 2018 GMC Yukon XL impresses with its spaciousness and luxurious feel, making it a standout choice for families requiring ample room for passengers and cargo. This large SUV provides significant advantages over its shorter counterpart, the GMC Yukon, through its extended wheelbase, which not only enhances legroom but also increases cargo capacity. With three robust powertrain options including a standard 5.3L V8 engine, a more powerful 6.2L V8, and a fuel-efficient 3.0L Duramax turbo diesel engine, the 2018 Yukon XL caters to diverse needs ranging from everyday driving to heavy towing. While it is often praised for its comfort and build quality, some owners have pointed out minor issues such as dings and dents and occasional screen malfunctions, although these do not seem to significantly detract from the overall appeal of the vehicle.
