A notable difference between the XT4 and XT5 is the dimensions of the two SUVs. The Cadillac XT4 has increased passenger volume while the Cadillac XT5 has increased cargo space. Both SUVs seat the same number of passengers, but the XT5 allows you to pack more luggage or groceries in addition to your passengers. While both SUVs are comfortable, sophisticated and luxurious, the XT4 offers passengers more space. Ask a member of our Rick Hendrick Cadillac Norfolk team to answer your questions further.
