Full-size SUVs, also known as large SUVs, generally refer to SUV models with a body length greater than 5000mm and a wheelbase exceeding 3000mm.
We also consider the brand's definition of its competitors as a basis for classification. For example, the X1/X3/X5 correspond to compact/mid-size/mid-to-large SUVs, respectively, while competitors, the Q5/Q7, correspond to compact/mid-size/mid-to-large SUVs, respectively. At the same time, the M-Class/GL-Class correspond to mid-size/mid-to-large/full-size SUVs, respectively.
