Size and Dimensions
One of the most noticeable differences between the BMW X3 and X5 is their size. The X3, being a compact SUV, is more maneuverable and easier to park in urban environments. It measures 187.2 inches in length, 75.6 inches in width, and 65.4 inches in height.

Cargo space is another area where the size difference becomes apparent. The X3 provides 28.7 cubic feet of cargo space behind the second row, which expands to 62.7 cubic feet with the rear seats folded down. The X5 offers a more generous 33.9 cubic feet behind the second row and 72.3 cubic feet with the seats folded, making it better suited for families or those who frequently need to transport large items.

Both the X3 and X5 offer a range of powerful engines, but the X5 generally provides more potent options due to its larger size and higher price point.
