2012 GMC Acadia Fuel Economy

6.0
Fuel Economy

As is the case with most large crossovers, the 2012 GMC Acadia rates well enough in highway fuel economy, but often checks in with averages closer to the lower city-cycle ratings.

The Acadia shares its six-speed automatic transmission with other GM vehicles, and as in those other crossovers, the wide span of gear ratios helps provide impressive performance.

It has reasonable fuel economy for an eight-passenger vehicle, but the 2012 GMC Acadia isn't a gas-mileage champion.
The EPA rates the Acadia at 17/24 mpg in front-drive versions, and at 16/23 mpg in all-wheel-drive models. We think those figures are optimistic. In repeated test drives of the Acadia and its Buick Enclave and Chevy Traverse siblings, we've only seen real-world gas mileage near the bottom of that scale.
