Cargo and load capacity limited by weight and distribution.
ALL-WHEEL DRIVE (AWD) This is great if you’ll be
trailering over wet or snow-covered roads on a regular basis.
The Acadia, Acadia Denali, Terrain and Terrain Denali offer
available advanced AWD designs that distribute power to front
and rear axles, allowing every wheel to provide driving power.
REAR-WHEEL DRIVE Rear-wheel-drive models are
standard on Canyon, Sierra, Sierra HD, Yukon, Yukon Denali
and Savana vehicles. The addition of cargo increases weight
on the rear, increasing traction. Rear-wheel-drive vehicles
typically have lighter chassis weights, resulting in better fuel
economy

than all-wheel-drive and four-wheel-drive vehicles.
The lighter chassis also allows you to dedicate more of the
vehicle’s load-carrying capacity to cargo weight.

FOUR-WHEEL DRIVE This gives you the option of enjoying
outstanding traction on demand. All Yukon and most Canyon
