Plus, you get a smooth-shifting nine-speed automatic transmission, no matter which model or configuration you choose, ensuring a refined drive.
The XT5 is more efficient, offering a few extra miles per gallon compared to the XT6 in both FWD and AWD formats.

The main difference between XT5 and XT6 models is size and seating capacity. Though both are midsize luxury SUVs, the XT5 has seating for up to five across two rows, while the XT6 seats up to seven across three rows.

Which midsize luxury Cadillac SUV you should buy depends entirely on your needs. If you're looking for a versatile model with a smaller form factor and plenty of cargo volume with the rear seats up, the XT5 may be right for you.
