Gas mileage remains the same as before with the Buick Enclave--with highway figures in the mid-20s, it's competitive with other seven- and eight-passenger crossovers, if not particularly efficient overall.
The front-wheel-drive edition of the Enclave is rated by the EPA at 17 miles per gallon city, 24 miles per gallon highway. It's not significantly different from vehicles like the Ford Flex, and it does apply to a vehicle capable of carrying up to seven passengers. Still, the overall numbers come in far below that of many five-passenger family sedans--vehicles often overlooked in the rush to buy a crossover wagon.
The figures drop to 16/22 mpg when all-wheel drive is ordered.
Those EPA numbers, even at that, seem a little optimistic based on the real-world observations of our editors along with other review sources. In our last significant stint with a previous mode-year Enclave, we saw an indicated 17 mpg over a mix of conditions.
