The GMC Acadia gets many improvements for 2013, but fuel economy isn't one of them. As a large, heavy crossover vehicle that doesn't incorporate hybrid technology, the Acadia gets highway fuel economy that some may deem acceptable. But its city ratings may be harder to stomach.
The EPA rates the Acadia at 17/24 mpg in front-drive versions, and at 16/23 mpg in all-wheel-drive models. Based on past drives in the Acadia, as well as the nearly identical Chevrolet Traverse and Buick Enclave, we tend to think those figures are a little optimistic.
