Key Differences
-
The Acadia has 45% more cargo space
On cargo (behind rear seats), the Acadia posts 23 cu ft against 15.9 cu ft for the CX-90, a gap big enough to feel in everyday use. The Acadia’s larger cargo area makes family trips and big shopping runs easier.
-
The Acadia has 48 hp more power
This is one of the widest gaps in the whole comparison: 328 hp for the Acadia versus 280 hp for the CX-90. The Acadia’s extra output gives it more in reserve when you need to get up to speed.
-
The Acadia has 30% more maximum cargo space
The CX-90 lists 75.2 cu ft; the Acadia comes in at 97.5 cu ft. That’s not a rounding error. The Acadia can swallow more with the seats down, which makes it more versatile for occasional big loads.
-
The CX-90 has better fuel economy
The CX-90 wins this narrowly, 25 mpg against 23 mpg, which makes it more of a bonus than a reason to buy. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The CX-90 has room for 8 seats
The CX-90 has a modest edge on seats: 8 seats against 7 seats for the Acadia. Third-row seats are often best for kids, so check legroom figures if adults will sit there.
