Buick MPG Guide

Which Buick gets the best mileage is no contest: the honors go to the Encore GX subcompact SUV! In order to earn up to 29 MPG in the city and 32 MPG on the highway, you’ll need to configure the Encore GX with front-wheel drive and equip the optional turbocharged engine. 

Moving down the Buick gas mileage ranks, you’ll find that in general, the larger and heavier models aren’t able to deliver as many miles on a full tank of gas. Also, models with front-wheel drive tend to get better gas mileage than those with all-wheel drive. That’s because FWD vehicles send power only to the front axle, while AWD vehicles send power to both axles—which uses more energy and more fuel.

Which Buick Gets the Best MPG?

Ranking Buick gas mileage from best to worst essentially means listing the lineup’s models by size in ascending order, as you can see in the Buick MPG chart above. Here’s what Dearborn shoppers should note:

• The Encore GX subcompact SUV gets the best Buick gas mileage—30 combined city/highway MPG—by a meaningful margin. The surprise here is that the 155-horsepower turbocharged 1.3L three-cylinder engine upgrade makes better gas mileage than the engine that comes standard for this model, a 137-horsepower turbocharged 1.2L three-cylinder engine (26/29 city/highway MPG).
• The all-wheel drive version of the Encore GX subcompact SUV is tied with the front-wheel drive Encore for second place, with both earning a combined city/highway MPG of 27. In other words, the Encore GX is the better buy if you’re looking for the enhanced traction and all-terrain capacity of an AWD vehicle, without sacrificing much fuel economy.
• The Buick Envision compact SUV actually outpaces the Encore subcompact model, which is impressive given its larger size. Even at its lightest, the Envision has a curb weight of nearly 3,700 pounds; the Encore is four to five hundred pounds lighter.
