Cargo and trailering ratings vary by configuration and equipment.
Always review vehicle-specific specifications and trailering requirements.

Terrain vs. Acadia Size & Seating

The biggest difference between these two GMC SUVs is size. The Terrain
is a two-row small SUV with seating for up to five. Its smaller footprint
can make it easier to maneuver through parking lots, garages and busy
streets while still providing useful passenger and cargo space.

The Acadia is a larger three-row SUV. Depending on configuration, it can
seat up to eight passengers, making it the more practical choice for
drivers who regularly need a third row or additional passenger capacity.

Which Has More Cargo Space?

The Terrain provides up to 63.5 cubic feet of maximum cargo volume with
the rear seats folded. That gives it useful flexibility for groceries,
luggage, sports equipment and everyday cargo without requiring a
three-row SUV.

The Acadia offers considerably more room. With the second and third rows
folded, maximum cargo volume reaches 97.5 cubic feet. It also provides
23.0 cubic feet behind the third row, allowing you to carry cargo even
when all three rows are in use.

Terrain vs. Acadia Performance

The 2026 Terrain uses a 1.5L turbocharged engine producing 175 horsepower.
Its powertrain is designed around the needs of a smaller SUV, with
available all-wheel-drive capability depending on configuration.

The larger Acadia uses a 2.5L turbocharged engine producing 328 horsepower
and 326 lb-ft of torque, paired with an 8-speed automatic transmission.
The additional output complements the Acadia’s larger size, greater
passenger capacity and higher available trailering capability.

Which GMC SUV Is Better for Towing?

For shoppers who plan to tow regularly, the Acadia provides the greater
maximum capability. A properly equipped 2026 Acadia can tow up to
5,000 pounds.

Properly equipped AWD Terrain models can offer up to 1,500 pounds of
maximum trailering capability. For lighter recreational equipment this
may be sufficient, but shoppers with larger trailers should compare the
Acadia’s additional capability.

Terrain AT4 vs. Acadia AT4

Both SUVs offer an AT4 model for drivers looking for additional
all-weather and off-road-focused capability.

The Terrain AT4 includes standard AWD, lifted ride height, all-terrain
tires, metal underbody protection and an AT4-exclusive Terrain Mode.
Its smaller dimensions create a compact approach to GMC’s AT4 formula.

The Acadia AT4 applies the AT4 concept to a larger three-row SUV. It
features an Active Torque Control AWD system, off-road-tuned suspension,
lifted ride height, all-terrain tires and an AT4-exclusive Terrain Mode.

Terrain Denali vs. Acadia Denali

Terrain Denali adds GMC’s premium styling and amenities to the smaller
two-row SUV. It is a good fit for shoppers who want an upscale GMC
without needing three rows of seating.

cabin and significantly more cargo space. The 2026 Acadia lineup also
offers Denali Ultimate for shoppers looking for the highest level of
luxury within the Acadia family.

technology. The 2026 Terrain features a standard 15-inch diagonal
