XT5 vs XT6
The shared Cadillac logo is where the obvious similarity ends. The XT5 and the XT6 come from different lines, and each line has its own idea of what matters. Trade-offs cut both ways here: pick the XT5 and you gain on fuel economy & range; pick the XT6 and you gain on off-road & towing.

Key Differences
-
The XT5 has 138% more cargo space
Of all the specs we compared, this is one where the XT5 makes its strongest case: 30 cu ft against 12.6 cu ft. The XT5’s larger cargo area makes family trips and big shopping runs easier.
-
The XT6 has room for 7 seats
The XT6 clearly leads on seats, and 7 seats versus 5 seats is a difference that reaches well beyond the spec sheet. Extra seats mean you can take more people along without taking a second car.
-
The XT6 has 25% more maximum cargo space
On cargo (seats folded), the XT6 posts 78.7 cu ft against 63 cu ft for the XT5, a gap big enough to feel in everyday use. Check the shape of the load floor too: a flat floor can matter as much as the number.
-
The XT6 has 500 lb more towing capacity
Not a big gap, but a consistent one. The XT6’s 4,000 lb beats the XT5’s 3,500 lb. If you tow regularly, the XT6’s higher rating gives you more margin.
-
The XT5 has better highway fuel economy
The XT5 wins this narrowly, 29 mpg against 27 mpg, which makes it more of a bonus than a reason to buy. Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.
Design & Size
The XT6 is physically larger, so the XT5 will be the easier fit wherever space is limited.

Engine & Performance
Too close to call
The engine & performance specs are close enough that neither gets the point. For engine & performance, pick whichever you prefer for other reasons.
Fuel Economy & Range
XT5 leads
The XT5 edges the fuel economy & range section, though the XT6 stays close. Choose the XT5 and you get better highway fuel economy. Highway fuel economy matters if you cover long distances at steady speeds. In short, the XT5 is the better-equipped car for fuel economy & range.
Fuel economy (highway)
XT5: 29 mpg XT6: 27 mpg The XT5 uses less fuel on the highway, a real saving on road trips and long commutes.
Space & Practicality
Trade-off
The space & practicality section is split: the XT5 has 138% more cargo space, while the XT6 counters with room for 7 seats. The space & practicality verdict depends on you more than on the spec sheet.
Cargo (behind rear seats)
XT5: 30 cu ft XT6: 12.6 cu ft Cargo figures are measured in different ways by different makers, so small gaps may not show in practice.
Seats
XT5: 5 seats XT6: 7 seats Third-row seats are often best for kids, so check legroom figures if adults will sit there.
Off-road & Towing
XT6 leads
A modest lead on off-road & towing belongs to the XT6. The XT6 pulls ahead with 500 lb more towing capacity. Towing ratings depend on configuration and equipment, so check the exact trim you’re looking at. The takeaway: on off-road & towing, the XT6 is the stronger car.
Max towing
XT5: 3,500 lb XT6: 4,000 lb A higher towing capacity lets you pull bigger trailers, boats and campers.

Price & Value
The XT5 launched for $4,900 less, a gap small enough that the specs should decide. Both have their wins, which makes the XT5’s $4,900 lower launch price more meaningful.
All prices are official US launch prices, last checked launch. Actual prices at stores may differ.
