The
Buick Encore
is the undefeated champion of fuel efficiency for the iconic American carmaker—but it’s not the only Buick with great gas mileage. 
Buick was one of the first names in the American automotive industry and the originator of General Motors. More than 120 years later, it’s still a name that stands for premium quality, comfort, and luxury—but it is behind the times when it comes to fuel efficiency? Has this historic brand run out of gas?

Which Buicks have the best gas mileage?

The top two Buick models for gas mileage are the Buick Encore subcompact crossover SUV and the
Buick Envision
compact crossover SUV: 
  • 2023 Buick Encore: up to 30 MPG combined
  • 2023 Buick Envision: up to 27 MPG combined
But let’s break it down a little further—and look at some competitors to help you make the call.

The most fuel-efficient Buick cars

If it’s flat-out efficiency you’re looking for, your best bet is the 2023 Buick Encore GX FWD. It’s a subcompact crossover SUV with better gas mileage than any Buick, although you’ll find plenty of better options from other manufacturers on the road.
Powered by a 137-horsepower turbocharged 1.2-liter three-cylinder engine, the Encore gets an EPA-estimated 29 mpg in the city and 32 mpg out on the open highway. It starts at just $25,900 MSRP, which is a great price for good fuel economy and all the luxury, comfort, space, and quality driving you expect from a Buick SUV. 
The good news for your budget is that you can pick up a 2022 Buick Encore GX FWD and get the same fuel economy while both versions of the 1.3-liter engine also have the same 30 mpg combined.
If you opt for the Encore GX AWD, you lose some of that efficiency, dropping down to 27 mpg combined. The 2022 Buick Encore FWD with a 1.4-liter engine also has 27 mpg combined.
The runner-up is the
2023 Buick Envision
, a compact crossover available from $33,400 MSRP. It’s another SUV with a comfortable ride, good engine power, and impressive fuel economy. While it might lag slightly behind the Encore, its FWD with a 2.0-liter engine delivers a combined mpg of 26, only dropping to 25 depending on your choice of model.
Bringing up the rear in Buick’s gas mileage rankings is the
2023 Enclave
. It’s a mid-size luxury SUV with sophisticated looks, plenty of room for passengers, and competitive pricing—starting at $43,300 MSRP. But it doesn’t quite match up when it comes to mileage. 
With 17-18 mpg for city driving and 25-26 mpg for highways, the Enclave offers between 20 and 21 mpg combined, depending on your set-up. That’s quite a drop from the Encore, though it’s competitive for the mid-size SUV market and comparable to the mileage offered by the
Kia Telluride
,
Chevrolet Traverse
, and
Honda Passport
