The 2026 Chevrolet Equinox EV and Blazer EV dominate the efficiency rankings with their all-electric powertrains. The Equinox EV FWD leads the pack at 2.2 Le/100 km combined, rated at 513 km of range. If you need all-wheel drive, the Equinox EV AWD delivers 2.3 Le/100 km combined with 494 km of range - still incredibly efficient.
The Blazer EV LT FWD matches the Equinox EV AWD at 2.3 Le/100 km combined with 502 km of range. Step up to the Blazer EV LT or RS AWD, and you'll see 2.5 Le/100 km combined with 455 km of range. Even the performance-focused Blazer EV SS AWD - which delivers 615 hp - returns 2.8 Le/100 km combined with 486 km of range. For buyers who want zero tailpipe emissions and the lowest operating costs, these electric SUVs are the clear winners.
If you're not ready to make the switch to electric, the 2026 Chevrolet Trailblazer offers the best fuel economy among gas-powered Chevrolet and GMC SUVs. The Trailblazer with the 1.3L turbo engine and FWD returns 7.7 L/100 km combined - competitive for a small SUV with room for five passengers and 716 litres of cargo behind the rear seat.
The Trailblazer 1.2L FWD is nearly as efficient at 7.8 L/100 km combined. If you need all-wheel drive for Canadian winters, the Trailblazer 1.3L AWD delivers 8.7 L/100 km combined - still respectable for an AWD compact SUV. With a 50-litre fuel tank, you can expect over 550 km of range on a single fill-up with the FWD models.
The 2026 Chevrolet Trax slots in just behind the Trailblazer at 8.1 L/100 km combined. Its 1.2L turbo engine produces 137 hp - enough for city driving and easy highway cruising. The Trax is ideal for buyers who want a small, easy-to-park SUV with low running costs.
The 2026 Chevrolet Equinox and GMC Terrain offer similar efficiency in the mid-size segment. The Equinox FWD returns 8.7 L/100 km combined, while the Equinox AWD delivers 8.9 L/100 km combined. The Terrain FWD matches the Equinox FWD at 8.8 L/100 km combined, and the Terrain AWD returns 9.3 L/100 km combined.
Both models are powered by a 1.5L turbo engine producing 175 hp. If you need more space than the Trailblazer or Trax but want to keep fuel costs reasonable, the Equinox and Terrain are solid choices. The Equinox offers slightly better efficiency, but the Terrain's upscale interior and refined ride may appeal to buyers who prioritize comfort.
The 2026 Chevrolet Blazer AWD with the 2.0L turbo engine returns 9.9 L/100 km combined. If you opt for the 3.6L V6, efficiency drops to 11.2 L/100 km combined. The Blazer is built for buyers who want a sportier, more powerful SUV - but you'll pay for it at the pump. If efficiency is your top priority, the Blazer EV is a better choice.
For buyers who need a full-size SUV, the 2026 Chevrolet Tahoe and Suburban with the 3.0L diesel engine offer the best efficiency in their class. The Tahoe diesel returns 9.9 L/100 km combined in RWD and 10.7 L/100 km combined in 4WD. The Suburban diesel is nearly as efficient at 10.2 L/100 km combined in RWD and 10.7 L/100 km combined in 4WD.
If you need to tow a boat or trailer regularly and want to minimize fuel costs, the diesel engine is the smart choice. The gas-powered Tahoe and Suburban with the 5.3L V8 return 14 L/100 km combined in RWD and 14.2 L/100 km combined in 4WD - significantly thirstier than the diesel.
The 2026 Chevrolet Traverse AWD returns 11.1 L/100 km combined with its 2.5L turbo engine. The GMC Acadia AWD delivers 11.2 L/100 km combined with the same engine. Both models seat up to eight passengers and offer over 1,600 litres of cargo space behind the first row. If you need three rows of seating and want to keep fuel costs in check, these are your best options in the Chevrolet and GMC lineup.
The 2026 GMC HUMMER EV SUV rounds out the electric lineup with 4.5 Le/100 km combined efficiency. Available in 2X and 3X configurations, both deliver approximately 500 km of range. While less efficient than the Equinox EV and Blazer EV, the HUMMER EV SUV offers strong off-road capability and towing capacity in an all-electric package.
The 2026 Chevrolet Equinox EV and Blazer EV lead the electric SUV segment in efficiency, competing directly with the Hyundai Kona EV and Kia Niro EV. The Trailblazer's 7.7 L/100 km combined rating is competitive with the Honda HR-V and Mazda CX-30. The Equinox and Terrain's mid-8 L/100 km ratings are on par with the Toyota RAV4 and Honda CR-V.
For full-size SUVs, the Tahoe and Suburban diesel models offer better efficiency than the Ford Expedition and Nissan Armada, both of which rely on gas-only powertrains. If you're cross-shopping full-size SUVs, the diesel option is worth considering.
No matter which Chevrolet or GMC SUV you choose, you can improve fuel economy with a few simple habits. Drive smoothly and avoid aggressive acceleration - jackrabbit starts waste fuel. Keep your tires properly inflated, as underinflated tires increase rolling resistance. Remove unnecessary cargo from the roof or trunk, as extra weight reduces efficiency.
For electric models like the Equinox EV and Blazer EV, precondition the cabin while plugged in to reduce battery drain. Use seat and steering wheel heaters instead of blasting the cabin heat in winter. Plan your routes to take advantage of public charging stations on longer trips.
