Long distances between towns, highway speeds for hours at a stretch and a fuel bill that shows up every week: that is the reality for a lot of prairie drivers. Fuel economy stops being a spec-sheet footnote and becomes the number you check first.
This guide ranks the 2026 Chevrolet, Buick and GMC lineup by Natural Resources Canada combined fuel consumption, from the most frugal subcompact to the diesel trucks and full-size SUVs. Every figure is an official NRCan rating in L/100 km, listed as city / highway / combined.

Subcompact SUVs: Under 8.2 L/100 km Combined
The 2026 Chevrolet Trailblazer takes the top spot at 7.7 L/100 km combined when equipped with the 1.3L turbo three-cylinder, 155 hp and 174 lb-ft, in front-wheel-drive form. Its 7.2 L/100 km highway rating is the lowest of any gasoline vehicle across the three brands.
The Buick Encore GX with the same 1.3L engine sits one tenth behind at 7.8 L/100 km combined, matching the 1.2L Trailblazer. The Buick adds QuietTuning sound insulation as standard, so the efficiency comes with a quieter cabin on long stretches.
The Buick Envista and Chevrolet Trax share a 1.2L turbo three-cylinder and a six-speed automatic. The Envista returns 7.9 L/100 km combined and the Trax 8.1 L/100 km, with both offering 7.4 to 7.6 L/100 km on the highway.
- Trailblazer 1.3L FWD: 7.7 L/100 km combined, the best in the lineup
- Encore GX 1.3L FWD: 7.8 L/100 km combined with standard QuietTuning
- Envista: 7.9 L/100 km combined with 1,189 L of maximum cargo space
- Trax: 8.1 L/100 km combined with 1,532 L of maximum cargo space
Compact SUVs: 8.7 to 9.5 L/100 km Combined
The Chevrolet Equinox and GMC Terrain share a 1.5L turbo four-cylinder rated at 175 hp. In front-wheel-drive form, the Equinox posts 8.7 L/100 km combined and the Terrain 8.8 L/100 km. Adding AWD moves the Equinox to 8.9 L/100 km and the Terrain Elevation to 9.3 L/100 km.
The Encore GX with AWD holds 8.8 L/100 km combined, which keeps it inside the compact group even with power going to all four wheels.
The Buick Envision, with its 2.0L turbo producing 228 hp and 258 lb-ft, rates 9.5 L/100 km combined with standard AWD and a nine-speed automatic.
Midsize and Three-Row SUVs: 9.9 to 11.2 L/100 km Combined
The Chevrolet Blazer with the 2.0L turbo and standard AWD returns 9.9 L/100 km combined.
Moving up to three rows, the Chevrolet Traverse and Buick Enclave both use a 2.5L turbo four-cylinder with 328 hp and 326 lb-ft, and both rate 11.1 L/100 km combined. The GMC Acadia with the same engine sits at 11.2 L/100 km.
For seven- or eight-passenger seating with 2,761 L or more of cargo space, those figures land close to what a five-seat midsize SUV returned a few years ago.
Trucks and Full-Size SUVs: The Duramax Diesel Advantage
The 3.0L Duramax turbo-diesel inline-six, with 305 hp and 495 lb-ft of torque, is the reason a full-size truck appears above several crossovers on this list. The Chevrolet Silverado 1500 with the Duramax in 2WD form posts 9.3 L/100 km combined and 8.3 L/100 km on the highway.
The GMC Sierra 1500 pairs the Duramax with 4WD at 10.1 L/100 km combined. In the full-size SUVs, the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon and GMC Yukon XL all rate 10.7 L/100 km combined with the diesel and 4WD.
Midsize trucks stay competitive on gasoline. The Chevrolet Colorado with the 2.7L TurboMax in 2WD form returns 11.1 L/100 km combined, and the GMC Canyon returns 11.4 L/100 km.
Skipping the Pump Entirely
For drivers ready to leave gasoline behind, the 2026 Chevrolet Equinox EV offers up to 513 km of estimated range on a full charge. The 2026 Chevrolet Blazer EV reaches up to 502 km in front-wheel-drive form, with a 1,500 lbs (680 kg) towing rating on LT and RS trims.
Which Efficient 2026 GM Vehicle Fits Your Driving?
Highway commuters get the most from the small turbo three-cylinders in the Trailblazer, Encore GX, Envista and Trax. A growing family that needs AWD lands in the Equinox, Terrain or Envision without giving up much at the pump.
If the work involves a trailer or a full crew, the Duramax diesel in a Silverado 1500, Sierra 1500 or Tahoe keeps combined consumption at or near 10 L/100 km.
- Best overall: Chevrolet Trailblazer 1.3L FWD at 7.7 L/100 km
- Best premium subcompact: Buick Encore GX at 7.8 L/100 km
- Best three-row: Traverse and Enclave at 11.1 L/100 km
- Best truck: Silverado 1500 Duramax 2WD at 9.3 L/100 km
